Surface quality and dry sliding wear behavior of AZ61Mg alloy using Abbott firestone technique

Currently, magnesium alloys are widely utilized in diverse sectors due to their unique properties. However, the AZ61Mg alloy, a commonly used magnesium alloy, is known to have poor wear resistance, which limits its applications. To address this issue, researchers have investigated various surface treatment techniques, including the Abbott Firestone method, to improve the wear resistance of this alloy. This study employs response surface methodology (RSM) to examine the effects of pressure and velocity on wear behavior and Abbott Firestone zones of AZ61Mg alloy. Three pressure (0.01, 0.015, and 0.02 MPa) and velocity (0.57, 0.76, and 0.95 m/s) levels are used to conduct dry sliding wear tests at room temperature using a pin-on-disc method with an experimental design technique (EDT). Analysis of variance ANOVA is employed to identify the relationship between the input parameters (pressure and velocity) and the responses (wear rate, Surface Roughness Parameter Rz, and Abbott Firestone zones) of the AZ61Mg alloy. The optimized models for wear rate and Abbott Firestone zones yielded accurate estimations, which can enhance cost-effectiveness and efficiency. The findings indicate that pressure and velocity significantly affect the wear behavior of the AZ61Mg alloy.

Mechanical Properties of Iron Plating Layer after Nitriding

A certain thickness of the iron plating layer without impurities was fabricated on the surface of pure iron by employing electroplating treatment. The thickness of the iron plating layer was measured by approximately 23 μm. SEM studies demonstrated the microstructure of the surface of the iron plating layer before and after nitriding. According to XRD analysis, the compound layer was mostly composed of Fe2-3N with high supersaturation of nitrogen. After nitriding, the microhardness of the sample was 555 HV with the depth of the matrix at 30 μm, which was four times the hardness of the matrix. Under the same experimental conditions, the wear volume loss and friction coefficient of the nitrided iron plating layer was lower, showing that nitriding can significantly improve the poor wear resistance of the iron plating layer. The Salt spray corrosion experiment showed that nitriding can significantly improve the corrosion resistance of the iron plating layer.

Effect of local pressure difference caused by argon flow on properties of DLC films on rubber

The application of a diamondlike carbon (DLC) coating on rubber surfaces is a promising method to enhance the tribological properties of rubber and alleviate its poor wear resistance. However, in the preparation of DLC films, accurate pressure detection in the sputtering region is challenging due to the single detection position in common sputtering systems. In this paper, the direct current magnetic sputtering method was used to prepare DLC films on nitrile butadiene rubber (NBR). A set of Faraday beam detection device (FBDD) was employed to monitor the current density in the sputtering region. It was found that even if the pressure at the detection position of the vacuum gauge is consistent, the actual pressure in the sputtering region may be different under different rates of argon flow based on the detection results from the FBDD. The surface energy of DLC films was also calculated and researched. According to the results of FBDD, a series of analytical characterization methods were selected to explore the influence mechanism of changing the Ar flow rate on the properties of DLC films on NBR when the initial sputtering pressure remained consistent. The results of FBDD show that the density of the beam in the sputtering region increases with the increase in the Ar flow rate introduced into the vacuum chamber. The surface energy of DLC films was also calculated and evaluated by a contact angle tester. Raman and x-ray photoelectron spectroscopy results indicate that the increase in the Ar flow rate leads to an increase in pressure, which is conducive to the formation of sp3 in DLC films, and the increase in sp3 improves the surface energy of DLC films. The highest sp3 content and surface energy among as-prepared DLC films are observed when the argon flow rate was 40 SCCM. Ball-on disk friction experiment was used to characterize the tribological performance of DLC films on NBR rubber and the adhesion between DLC films and NBR rubber was evaluated by a nanoscratching test. Combining the results of tribology and nanoscratching testing, it can be inferred that the Ar flow rate plays an important role in improving the mechanical properties of DLC films on NBR rubber. Furthermore, the results of scanning electron microscopy confirmed that the sputtering atoms can effectively fill in the grooves of the rubber substrate. This finding is of significance for controlling the sputtering process of preparing DLC on rubber and improving the frictional properties of rubber.

Rational Design of High-Performance Nanomaterials for Electric Vehicle Tires

In today's society, the market limitations of electric vehicle tires are relatively poor wear resistance and rolling resistance. These two problems restrict the further development of electric vehicles, accelerate energy consumption and environmental pollution, and bring hidden dangers to users. In this paper, the principle of tire wear resistance and the cause of excessive rolling resistance related to tire deformation are analyzed from the perspective of materials. At present, these two problems can be improved by adding nanomaterials to automobile tire materials (natural rubber and synthetic rubber). The tire's thermal conductivity and wear resistance can be improved by inserting Silica and a small amount of nano-diamond. This paper will also discuss the unique advantages of carbon black with different particle sizes as filler by analyzing the effects of modified Silica and carbon black on the molecular rubber chain. On this basis, this paper will also explain the drawbacks of nanofiller materials.

Research progress on the oxidation behavior mechanism and the design of antioxidant methods of artificial polymer acetabular cup

AbstractUltra‐high molecular weight polyethylene (UHMWPE) was once the most widely used clinical hip prosthesis‐bearing component due to its exceptional mechanical qualities and biocompatibility. However, the poor wear resistance of UHMWPE limits its service life in vivo. Radiation cross‐linking is a common means to improve the wear resistance of UHMWPE, and highly cross‐linked polyethylene (HXLPE) acetabular cup is gradually becoming the first choice in clinical practice. The residual free radicals generated by the cross‐linking process can accelerate the oxidation process of the polymer acetabular cup, which is not conducive to the long‐term in vivo service process. Heat treatments such as annealing or melting and the addition of antioxidants are potential methods to improve the antioxidant performance of HXLPE in vivo. Research into the oxidation characteristics of polymer acetabular cup is crucial for enhancing their durability in vivo and ensuring their long‐term performance reliability. In this paper, the research progress focuses on the oxidation mechanism, the influencing factors of the oxidation process of polymer acetabular cups, and the methods to improve their oxidation resistance. It discusses the reliability of improving the service life of UHMWPE acetabular cup in vivo and other alternative methods.Highlights Characteristics of polymer acetabular cups were systematically introduced. Mechanism of oxidative behavior of acetabular cup in vivo/in vitro was analyzed. Influencing factors of acetabular cup oxidation behavior were summarized. Methods for improving antioxidant properties of acetabular cups were summarized. New method was proposed to improve the antioxidant properties of acetabular cup.

Microstructure evolution and tensile property of high entropy alloy particle reinforced 316 L stainless steel matrix composites fabricated by laser powder bed fusion

316 L stainless steel is prone to failure under high-strength conditions due to low strength and poor wear resistance, which limits its further application severely. In this study, 2 wt% FeCoNiAlTi high entropy alloy (HEA) powders and 316 L stainless steel powders were mixed to fabricate HEA reinforced 316 L stainless steel matrix composites (MMCs) via laser powder bed fusion (LPBF). The influence of scanning speed on microstructure evolution, the mechanical properties and the strengthening mechanisms have been investigated systematically. The LPBF-fabricated HEA/316 L MMCs consists of both γ-Fe and α-Fe phases. For HEA/316 L MMCs, the grains are refined with the increase of scanning speed and the minimum size is around 0.64 µm. The precipitation of nanoparticles is observed, and the nanoparticles form a strong interfacial bounding with matrix, which indicates the good metallurgical bonding between HEA and 316 L stainless steel. The tensile strength of the LPBF-fabricated composites increases from 1164 MPa to 1276 MPa with increased scanning speed, which is approximately twice as high as the strength of LPBF processed 316 L stainless steel matrix. The contribution of each strengthening mechanism is calculated, and the contribution of particle strengthening is the largest (from 241 MPa to 300 MPa, changing with scanning speed). This work demonstrates the feasibility of using HEA as potential reinforcement in metallic systems and can further enlarge the application field of metallic materials.

A continuous polytetrafluoroethylene foam-coating to glass fiber mat with superior self-cleaning, antistatic and high filtration efficiency performances

Air pollution has become a significant global environmental issue, leading to adverse health effects and respiratory diseases. To address this challenge, expanded polytetrafluoroethylene (ePTFE) membrane-based fibrous filters have gained popularity in the past decade. However, the thinness and low mechanical strength of ePTFE membranes make them susceptible to damage from particle collisions. As an alternative to ePTFE membranes, PTFE emulsion has emerged as a promising approach to enhance filtration efficiency. However, due to PTFE's low surface energy and high crystallinity, it is difficult for PTFE to self-bond into a membranes and adhere to substrates. Therefore, the filtration efficiency of PTFE-impregnated filter materials does not meet the requirements for ultra-low emissions, and they have poor wear resistance, resulting in a short service life. Herein, we fabricate a PTFE emulsion foam-coating membrane filter. The influences of the contents of PVA on the film morphology, air permeability, pore size and distribution, abrasive resistance and antistatic properties were analyzed. The self-cleaning performance was simulated and the filtration performance was measured as well. Notably, the frictional mass loss index of the PTFE emulsion foam-coating membrane filter was 0.07. After 30 cycles, the filtration efficiency was 98.93%, and the strip ratio was 91.03%. Our design of the PTFE emulsion foam-coating provided a new direction for the application of PTFE emulsion in the filtration field with superior self-cleaning, antistatic and high filtration efficiency performances.

Research on strength formation mechanism and noise reduction characteristics of waste rubber powder micro-surfacing

The application and promotion of the traditional micro-surfacing is limited by the defects of high noise and poor wear resistance. In order to improve the adhesive strength and noise reduction properties of the micro-surfacing, an attempt was made to add waste rubber powder (WRP) in dry form to the micro-surfacing. Firstly, the mixtures were prepared by orthogonal tests taking into account the number of rubber powder grades, rubber powder dosages, asphalt-aggregate ratio and gradation. The microscopic strength formation mechanism at the micro-surfacing of the waste rubber powder was investigated by means of Scanning Electron Microscope (SEM). Secondly, the effect of waste rubber powder (WRP) on the modification of asphalt mastic was investigated with the Dynamic Shear Rheometer (DSR), both as unaged and after short-term ageing. Finally, the effect of waste rubber powder on the performance improvement and noise reduction characteristics of the micro-surfacing was analyzed through road performance tests, and to establish the correlation between microstructure and road performance. The results showed that 2% of 40-mesh rubber powder mixed with 8% asphalt-aggregate ratio of medium grade MS-3 micro-surfacing mixture, the densest structure of the slurry. Significantly improved high-temperature and ageing performance at the micro-surfacing reduced noise generation and suppressed noise transmission, but no significant improvement in water stability performance. The waste rubber powder enhances the strength of the micro-surfacing by interweaving with cement hydration products and asphalt mortar. It also optimizes the inter-aggregate embedding and void characteristics, and has an excellent noise reduction effect.

High-performance AlCoCrFeNi high entropy alloy with marine application perspective

2205 duplex stainless steel (DSS) and Incoloy 825 alloys are extensively utilized in the marine environment for decades but have some limitations of insufficient hardness and strength and poor wear resistance. Here, we developed AlCoCrFeNi high-entropy alloy (HEA), which showed a good combination of mechanical, wear-resistant and corrosion-resistant properties. Vickers hardness and compressive yield strength of AlCoCrFeNi HEA were ∼517.6 HV and ∼1306.4 MPa, respectively, which were much higher than those of 2205 DSS and Incoloy 825 alloys. Besides, there is a smaller wear rate and lower corrosion current density for AlCoCrFeNi HEA compared with those of 2205 DSS and Incoloy 825 alloys, suggesting good resistance to wear and corrosion damage. These merits are due to lattice distortion, high hardness and low grain boundary number per unit area. This work offers new insights for the development of wear- and corrosion-resistant HEA materials used in the marine environment.

Research and Optimization of the Influence of Process Parameters on Ti Alloys Surface Roughness Using Femtosecond Laser Texturing Technology

One of the major disadvantages of Ti alloys is their poor wear resistance. To increase their wear resistance, before applying a wear-resistant layer, the surface of the substrate should be carefully prepared to ensure the required coating adhesion. Femtosecond laser (fs) texturing is a technology that can be used for surface texturing of Ti alloys because it enables a controlled heat input on a small surface area. The process of laser texturing is very sensitive to the choice of input parameters, such as the number of passes (P) and laser power (W), the choice of which may significantly influence the ultimate surface roughness values (Ra). It cannot be expected that by using the fs process a given default Ra value will be achieved, but it is assumed that the obtained roughness values will be within the given interval. As a result of this research with a significance level of 95% using a design of experiments (DOE) and Monte Carlo simulations, a general linear model of Ra = f (P, W) and optimal input parameter intervals (P and W) of laser texturing were obtained both for the given interval as well as for the default surface roughness value (Ra). Considering that an industrial process is involved here, a process performance capability index (Cpk) has been also defined, which shows that optimal process parameter intervals give roughness values for the given interval or given default roughness value.

Superior wear resistance in cast aluminum alloy via femtosecond laser induced periodic surface structures and surface hardening layer

Cast Al alloys have been increasingly used in aviation, shipping, aerospace, and automotive industries as important raw materials of engine parts. However, its poor wear resistance hampered their application in some tribological environments. To overcome the current issue, in present work, we proposed a femtosecond laser (fs-laser) surface processing strategy to fabricate pillar-shaped laser induced periodic surface structures (LIPSS), as well as a work-hardening layer (hardness increment reached 51.2% compared with that of substrate) with an affected depth of ∼ 75 μm, on the surface of cast Al alloy in one step. In this case, the wear performance of processed samples showed an obvious improvement with a 49.4% reduction of the cross sectional area of wear track. Our work broke the existing understanding about the strengthening mechanism of fs-laser surface modification technology, in which surface texture or shock wave induced by fs-laser were viewed as two isolated strengthening effects. For the first time, we achieved the combination of these two strengthening effects, and proved the effectiveness of this strategy. The present results provided theoretical bases for the further development of novel fs-laser surface technologies with better performance.

Ultralow friction PTFE/PEEK heterolayer: A new solid lubrication approach toward simplicity

Tribological applications of polytetrafluoroethylene (PTFE) are often limited by technological complexity to overcome its poor wear resistance. Here, a PTFE/polyetheretherketone (PEEK) heterolayer (HL) was proposed and evaluated as a new solid lubrication solution. Pin-on-disk tribometry found the lowest friction coefficient (μ) of 0.031 and ultralow wear for the PEEK/HL under typical conditions. The friction coefficient of the HL surpasses those of the state-of-the-art polymeric coatings/composites by at least 200%, and approaches that of highly lubricated interfaces. Mechanistic investigations revealed multi-length physical and chemical heterogeneity of the HL that best facilitates a tribofilm with high subsurface stability and surface instability. The technological simplicity and robustness of the HL’s high lubricity make it a promising new type of solid lubrication toward greater reliability and longevity.

Effect of SiC nanowires on adhesion and wear resistance of hydroxyapatite coating on AZ31 magnesium alloy

Hydroxyapatite (HA) coatings doped with different contents of SiC nanowire (SiCnws) were prepared on the surface of AZ31 magnesium alloy by electrophoretic deposition to solve the problems of low adhesion and poor wear resistance of pure HA coatings. Performance tests were conducted on the coating, including corrosion resistance, adhesion and wear performance. The results showed that the prepared coating was intact. The adhesion and wear resistance of the coating were significantly improved when the doping amount of SiCnws was 3%. Among them, the adhesion increased by 37.06% and the scratch depth decreased by 86.67%. At the same time, the corrosion resistance of the coating still maintained a high level. It showed that the performance of doping 3% SiCnws modified coating was balanced and excellent in all aspects.

TiC–Fe gradient coating on pure titanium fabricated by in-situ solid-phase diffusion: toward superior hardness and interfacial adhesion strength

Protective hard coatings can significantly improve the bottleneck problem of low hardness and poor wear resistance on titanium alloy surface. However, hardness and adhesive strength usually exhibit an inverse relationship, which greatly limits its widespread use. In this work, TiC–Fe gradient coating with high hardness and adhesion was successfully fabricated by in-situ solid-phase diffusion method (ISDM) on pure titanium at 1000 °C for 2 h. The average thickness of the coating was approximately 5 μm, and the volume fraction of TiC in the coating was greater than 95 vol%. The grain size of TiC gradually increased from 200 nm at the coating surface to 2 μm towards the substrate. The phase interface and the coating/substrate interface exhibited excellent interfacial bonding at the atomic scale. The novel TiC–Fe gradient coating can simultaneously achieve superior hardness (42.9 ± 2.6 GPa) and elastic modulus (557.4 ± 10.3 GPa) that is mainly dominated by in situ synthesised high volume fraction TiC, as well as high adhesion strength (>225 ± 10 MPa). The increased adhesion strength was attributed to the excellent macro/micro interfaces and gradient transition of the microstructure. The use of ISDM to fabricate TiC–Fe gradient coating on titanium alloy may provide a new strategy to improve the comprehensive properties including hardness, elastic modulus, interfacial adhesion strength, and wear resistance for wider applications.

Reinforced PTFE composites with atomized powder of Inconel 625 alloy for sealing application: Study of structural properties and molecular dynamics simulation

Polytetrafluoroethylene (PTFE) is one of the most used materials for sealing applications. Despite remarkable properties, PTFE has poor wear resistance which causes leakage problems during sealing. Studies have shown that the most important factor for improving the sealing properties of the PTFE matrix is adding suitable fillers as the reinforcing phase. Therefore, the design and fabrication of the PTFE-based composite with new reinforcements is a highly demanded research to enhance sealing properties. In this investigation, atomized powder of the Inconel 625 alloy which is a Nickel-based superalloy was used as a reinforcing phase to fabricate the PTFE-based composite. The effect of different weight percentages of the Inconel 625 was investigated on the wear, corrosion, and leak rate properties of the PTFE-based composites. The result showed that the predominant abrasion mechanism of the PTFE/Inconel 625 composite is the usually adhesive type with proper corrosion resistance against hydrochloric acid, sulfuric acid, and hydrogen fluoride. Among the fabricated composites, the mixture of 50 % Inconel 625 alloy and 50 % PTFE exhibited the best combination of properties with a leak rate of approximately 10−9 mbar L s−1. Besides, the molecular dynamics (MD) simulation was applied to study the interface of the PTFE and the Inconel 625 alloy particles, the wear, and the permeability behavior of the composites. Based on the obtained results, the novel PTFE composite can be applied as a sealing application for industrial purposes.

Investigation of New Material for Deterging Heat Exchanger Tube

This work represents new material can be used in cleaning process of heat exchanger tubes. Rubber projectiles are back bone of on line cleaning mechanism but it has poor mechanical and thermal features. Three materials have different properties with micro scale powder solid phase (aluminum, aluminum oxide and copper) had been added to (LSR) with different volume ratios (2%, 5%, 10%, 15%). specimens had been prepared with certain method and under specific conditions. Compression test was applied to identify stiffness factor of these new composite materials. Wear test was applied to finite the wear rare coefficient for these materials. Un certainty statistics was applied for measurements results so It's founded that with increasing volume ratio each of stiffness factor and wear rate coefficient increase linearity up to (15%) for all specimens. copper filler give best for stiffness that stiffness factor reaches about (30 (N/(mm/mm))) at volume ratio 15%) but poorest wear resistance with wear rate coefficient (9*10^-6) Mpa^-1 inversely aluminum filler gives best results in wear resistance with wear rate coefficient (6*10^-6) Mpa^-1 but weakest in stiffness test with stiffness factor (28 N/(mm/mm) at volume ratio 15%). Aluminum oxide was the best choice for new projectile material as it combines between good stiffness and wear resistance.

Study of Wear and Corrosion Resistance of Cold Sprayed TC4 Coating on the Surface of Mg-Li Alloy

Mg-Li alloys have achieved vital applications in aerospace, automotive, and 3C fields for their prominent properties. However, the Mg-Li alloy exhibits poor corrosion and wear resistance due to the high activity of Mg and Li elements and low hardness of Mg. Accordingly, TC4 alloy coating was prepared on the surface of Mg-Li alloy using the cold spray technique to enhance the surface properties. Moreover, the microstructure, microhardness, tribological properties, and corrosion resistance of the coating were systematically investigated. As indicated by the results, the interface between the coating and the Mg-Li alloy substrate was mechanical bonding without significant defects. Several pores exist in the cold sprayed TC4 coating for its high elasticity, toughness, and passivation, resulting in a porosity of 4.3%. The microhardness of the cold sprayed TC4 coating reached 296.3 HV, marking a notable increase in comparison with the substrate. The TC4 alloy coating has better wear resistance than the Mg-Li alloy substrate. The wear volume of the cold sprayed TC4 alloy only accounted for 38% of that of Mg-Li alloy. Abrasive wear was the major wear mechanism of the TC4 alloy coating. In electrochemical tests, the corrosion current density of the TC4 alloy coating (1.426 × 10−5 A/cm2) was two orders of magnitude lower than that of the magnesium-lithium alloy substrate (1.008 × 10−3 A/cm2), and the corrosion potential of the TC4 alloy coating was higher, which indicates that the coating has excellent corrosion resistance.

A crack-free Ti-modified Al-Cu alloy processed by in-situ alloying laser powder bed fusion: Tribological behaviors and mechanical properties

High strength Al-Cu alloys are of great interest for processing using additive manufacturing for aerospace applications. In this study, a Ti-modified Al-Cu alloy was successfully processed by in-situ alloying laser powder bed fusion (LPBF). The relationship between the volumetric energy density (VED) and the densification of a Ti-modified and unmodified Al-Cu alloy was investigated. The results showed that a high-density, crack-free Al-Cu alloy can be achieved with the addition of Ti. Hot cracks occurred along the coarse columnar grains in the unmodified Al-Cu alloy due to the severe stress concentrations arising during the LPBF process. The elimination of hot cracks was attributed to the decrease of grain size and the change of grain morphology from columnar to equiaxed with the Ti addition. The tensile properties of the Ti-modified Al-Cu alloy were significantly improved with a yield strength of 200 MPa, an ultimate strength of 289 MPa, and an elongation to failure of 8 %. The strengthening mechanisms including grain refinement strengthening, solid solution strengthening and second phase strengthening were quantified and the fracture mechanism was discussed. The tribological results showed that a low wear rate of 3.03 × 10−4 mm3 N−1 m−1 was achieved in the alloy with Ti modification, while unmodified alloy showed a poor wear resistance. The study demonstrates a novel method to develop advanced Al-Cu alloy with high density, strength and tribological resistance by in-situ alloying LPBF.

Development of sustainable superhydrophobic coatings on aluminum substrate using magnesium nanoparticles for enhanced catalytic activity, self-cleaning, and corrosion resistance

This study focuses on the development of sustainable superhydrophobic surfaces (SHSs) using magnesium nanoparticles (Mg-NPs) for catalytic applications and achieved excellent SHSs on the aluminum substrate along with a high static water contact angle of 160° and a low sliding angle of 2° via etching, immersion, and annealing method. The changes in surface chemistry, structural composition, and surface morphology were examined by using various characterization techniques, such as X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Herein, we describe the creation of Mg-NPs @SHS which is facile, eco-friendly, mechanically stable and fluorine-free, along with surface robustness as compared to other SHP coatings present in the literature whose surface textures become fragile and poor wear-resistance due to direct/indirect involvement of toxic chemicals such as fluorocarbons along with complicated preparation processes and costly processing procedures. It showed a low value of Ecorr (−0.425 V) and a high value of Icorr (2.016 × 10−5 A cm−2) than a non-coated Al plate of Ecorr is (−0.801 V) and Icorr (4.998 × 10−3 A cm−2). It has also remarkable self-cleaning, super buoyancy, anti-icing property, and excellent catalytic reduction of 4-NP to 4-AP with efficiency of 99.82% in the 1st and 84% in 13th cycle. These findings suggest that Mg-NPs @SHS on the aluminum substrate have promising applications in sustainable environmental practices and provide valuable insights for the fabrication of superhydrophobic surfaces on different materials. This work offers a new avenue for the development of high-performance catalysts with reusability and durability composed of magnesium particles.

Mechanical and wear characteristics of spark plasma sintered titanium/multilayer graphene nanocomposites

Owing to excellent mechanical properties, Titanium (Ti) alloys have been of great interest in recent years. However, due to their poor wear resistance application of these alloys is restricted in the areas involving wear and friction. To address such challenges, in the current work, multilayer graphene (MLG) reinforced titanium matrix composites have been fabricated via the spark plasma sintering process. The content of MLG in Ti6Al4V powder is varied between 0% and 1.2%. The present work explores the influence mechanism of MLG addition in Ti6Al4V by investigating fabricated nanocomposites’ microstructure, nanohardness and wear behaviour. Microstructural study reveals an in-situ reaction between a carbon source from MLG and Ti from the Ti6Al4V to form a secondary phase TiC. Moreover, due to the formation of TiC, an increase in the nanohardness value of sintered nanocomposites Ti6Al4V/1.2 wt.% MLG (5.39 GPa) was recorded when compared to fabricated Ti6Al4V alloy (3.23 GPa). Dry sliding wear tests were performed under loads of 3–7 kg. It was observed that Ti6Al4V/1.2 wt.% MLG nanocomposite shows the maximum wear resistance across various sliding velocities with a minimum wear rate of 15 × 10−6 g/m. It is evident from the results obtained that MLG plays a vital role in improving the microstructural, mechanical, and tribological properties of sintered nanocomposites.
