Wear characteristics of a CNTs reinforced aluminium composited fabricated by the solution mixing process

Aluminium-carbon nanotube (Al-CNT) composites have proven to offer a lot of potential for applications involving friction and wear. This study investigated the wear behaviour of Al-CNT composites with uniformly dispersed CNTs without structural damage at concentrations of 0.5 wt%. The wear behaviour of these composites has been compared with that of pure aluminium, which was fabricated using the identical wet shake mixing, compaction, and extrusion procedure. The study aimed to determine how CNT concentration and applied stress influence the wear behaviour of composite materials. Scanning electron microscope (SEM) was used by the researchers to examine the surface features of the worn samples. The study showed a significant increase in hardness and wear resistance with adding CNT. Compared to pure aluminium, the composite containing 0.5 wt. % CNTs demonstrated a 25% reduction in wear rate, and the average value of the coefficient of friction (µ) also decreased. The wear rate and coefficient of friction increased when samples containing 0.5 wt. % CNTs were subjected to various loading scenarios. The major contribution of CNTs to improving wear characteristics was discovered through SEM investigation of these worn surfaces. Using the ANSYS Workbench, a built finite element model was used to perform contact analysis on the disc and pin. Analytical results and experimental data were contrasted, and the ANSYS data was utilised to assess the process parameters. The comparison confirmed the analysis accuracy and dependability, which showed a consistent agreement between the analytical findings and the experimental results.

Study on the grinding surface quality of CNTs/2009AL composite material based on minimum quantity lubrication

Carbon nanotube aluminum matrix (CNTs/AL) composites are ideal lightweight and high-strength materials due to their excellent properties. However, the research on CNTs/AL composites only stays in the simulation and preparation stages, and no grinding research has been carried out. Revealing the grinding mechanism of CNTs/AL composites has far-reaching significance for the development of high-end equipment industries such as aerospace. Taking CNTs/2009AL composites as the research object, a minimum quantity lubrication (MQL) flat grinding platform was built for comparing the surface quality and defects of dry grinding and MQL grinding. The experimental results show that grinding wheel velocity was the grinding parameter that had the greatest influence on surface roughness in dry grinding and MQL grinding. The subsurface defects of dry grinding mainly included microcracks, burrs, pits, coatings, cavities, etc., and the rebound phenomenon of agglomerated carbon nanotubes. The subsurface defects of MQL grinding were only burrs and pits. The surface coating phenomenon of dry grinding increased with the increase in grinding wheel velocity, and the surface quality was improved. MQL grinding could significantly reduce grinding heat, reduce friction, and make the machined surface smoother. In dry grinding and MQL grinding, the subsurface damage depth decreased obviously with the increase in grinding wheel velocity. When the grinding wheel velocity was 30 m/s, the minimum subsurface damage depth of dry grinding and MQL grinding was 40.091 and 26.906 μm, respectively. Mastering the grinding mechanism of grinding CNTs/AL composites and the influence of grinding parameters on surface quality provides a basis for the selection of parameters and methods in grinding in industry. MQL grinding of CNTs/AL composites reduces the formation of many surface defects and improves the surface quality of the workpiece. It is an efficient, clean, and environmentally friendly processing method.

Space confinement effect of carbon nanotube-alumina strip support on the Cu-Co catalysts for CO2 methanation

The present work reported the space confinement effect of carbon nanotube-alumina strip (CAS) support on the Cu-Co bimetallic catalyst or the single Cu, Co catalysts for the CO2 methanation. CAS, made by extrusion of nanotubes and Al-based sol and high temperature calcination, was a macroscopic support with sufficient mesopores and hydrophobic property. Cu-Co/CAS catalysts exhibited high catalytic activity for methanation of CO2 (H2/CO2=3:1), where CO2 conversion was 49.62% and CH4 selectivity was 95.98% at temperature as low as 250 ℃ and 1.5 MPa, and showed advantage significantly over those with the supports of individual nanotube or pure Alumina support. The comparison suggested the hydrophobicity of carbon nanotubes can effectively remove water from the metal active sites, enhancing the equilibrium of reverse water gas shift and CO methanation reactions, as compared to alumina support. Additionally, CAS support had a spatial confinement effect that increased the contact time of CO2 or intermediates with the active sites, compared with individual nanotube support. XPS and Raman spectroscopy validated the presence of oxygen vacancies of CAS, promoting the CO2 methanation. H2-TPR results, in combination with DFT calculations, confirmed that the CAS supports enabled the Cu-Co active phase by changing their electronic structures, to possess a strong adsorption activation capacity for H2 at low temperatures with high performance for CO2 methanation.

This study examines the effect of sintering temperature variations on density values and Vickers hardness values on Aluminum Carbon Nanotubes. Tests were conducted using five temperature variations, namely sintering 400°C, 500°C, 600°C, 700°C, and unsintered. The results showed that the 400°C sintering temperature variation produced higher hardness values than the 500°C, 600°C, 700°C, and unsintered sintering temperature variations. AlCNT specimens at a sintering temperature of 400°C have an average hardness value of 46.92 VHN, while at a sintering temperature of 500°C have an average hardness value of 30.48 VHN, while at a sintering temperature of 600°C have an average hardness value of 29.04 VHN, while at a sintering temperature of 700°C have an average hardness value of 26.17 VHN, while at a sintering temperature of 0°C have an average hardness value of 39.79 VHN. Therefore, it is found that the best sintering temperature variation for AlCNT specimens is 400°C for the application of sintering to aluminum carbon nanotubes. In addition, this research can be a reference for further researchers in developing manufacturing methods and characterization of aluminum reinforced with carbon nanotubes to obtain optimal results.

PENGUJIAN KEAUSAN ALUMUNIUM MATRIX KOMPOSIT DIPERKUAT DENGAN KARBON NANOTUBE

Wear testing of engineering materials is an important aspect in evaluating their performance and durability. This study aims to investigate the wear-resistant ability of aluminum composites reinforced with carbon nanotubes (CNTs). The composite manufacturing process was carried out by infiltrating CNTs into the aluminum matrix through powder metallurgy method. Tests were conducted using two methods, namely pressing and sintering with temperature variations of 0oC (non sintering), 400oC, 500oC, 600oC and 700oC. The results showed that the specific wear value on the specimen obtained the best value at a sintering temperature of 400oC with a value of 0.003632850 mm3/kg.m and the highest value at a sintering temperature of 700oC with a value of 0.042771207 mm3/kg.m. And the wear rate on the specimen obtained the best value at a sintering temperature of 400oC with a value of 0.447887285 mm3/s and the highest value at a sintering temperature of 700oC with a value of 1.155387594 mm3/s. This shows that the addition of temperatures greater than 400oC has a major influence on the specific wear value and wear rate of sintering products. In addition, this method is also a reference for further researchers in developing aluminum carbon nanotube technology to obtain optimal results.

Ceramic based nanocomposites with alumina-carbon nanotube reinforcement for improved energy absorption in sports-related injuries: Microstructural analysis and low velocity impact

This study aimed to investigate the impact of incorporating nanoparticles on the energy absorption properties of nanocomposites using low-velocity impact (LVI) testing and molecular modeling. Various types of thermoset polymer-based nanocomposites reinforced with carbon nanotubes (CNTs) and alumina were analyzed, and the effect of adding two types of nanofillers and microfiber as a filler material was investigated. The results show that the addition of nanoparticles significantly improved the elastic energy absorption properties of the nanocomposites at the atomic level. The LVI tests demonstrated that adding both types of nanoparticles, along with microfiber, significantly enhanced the energy absorption capacity of the four-phase composite under practical conditions. The scanning electron microscope (SEM) analyses revealed the morphology behavior of the nanoparticles. Incorporating both types of nanoparticles simultaneously with the polymer and fibers increased the elastic modulus by up to 163 %. These findings have significant implications for designing structures with energy-absorbing materials to reduce sports-related injuries. The use of nanocomposites with enhanced energy absorption properties can help to improve the performance of energy-absorbing structures and reduce the risk of sports-related injuries.

Investigation of the Wear Behavior of Dual-Matrix Aluminum–(Aluminum–Carbon Nanotube) Composites

Aluminum (Al)–aluminum–carbon nanotube (Al–CNT) dual-matrix (DM) composites are a novel class of nanocomposite materials that combine the ductility of the Al matrix with the hardness and wear resistance of the Al–CNT composite and thus can offer a unique combination of properties that make them suitable for a wide range of wear applications such as cutting tools, bearings, brake pads, wear-resistant coatings, etc. However, the specific properties of the DM Al–(Al–CNT) composite will depend on several factors related to the material’s composition and the friction conditions. This study investigates the wear behavior of DM Al–(Al–CNT) composites consisting of a primary matrix of soft aluminum in which milled hard particles of (Al–CNT) are dispersed as affected by five parameters: (1) wt.% CNT in the reinforcement particles, (2) mixing ratio between the reinforcement particles and the soft Al matrix, (3) sliding speed, (4) applied load, and (5) distance. The experimental design used a Taguchi fractional factorial orthogonal array (OA) L27 to reduce the number of experiments, and analysis of variance (ANOVA) was used to determine the significance and to model the effect of each control parameter. Results showed that the wear rate could be reduced by up to 80% by tailoring the composition and controlling the friction conditions. It was found that the mixing ratio significantly impacts the wear behavior of DM Al–(Al–CNT) composites. A mixing ratio of 50% and a CNT content of 3 wt.% at the lowest applied load gave the lowest wear rate and coefficient of friction. Scanning electron microscopy investigations showed fragmentations in the reinforced matrix at higher loads and mixing ratios, which negatively impacted the wear behavior. Our findings confirm that DM Al–(Al–CNT) composites are promising for wear applications. However, the wear behavior depends on the composition and microstructural design of the composite, which needs to be carefully studied and understood.

The Interaction Pathway in the Mechano-Ultrasonically Assisted and Carbon-Nanotubes Augmented Nickel–Aluminum System

The influence of mechano-ultrasonic activation (MUA) and nano-additives (carbon nanotubes-CNT) on the interaction pathway of nickel–aluminum powder mixture at high heating rates was investigated. The optimum conditions of the mechano-ultrasonic activation, along with the phase and structure formation peculiarities of nickel–aluminum and nickel–aluminum–carbon nanotubes mixtures by thermal analysis method, the so-called high-speed temperature scanner (HSTS), were found out. The optimum duration of mechanical and ultrasonic activation aiming to achieve homogeneous distribution in the agitated mixtures was determined. A shift in characteristic temperatures of MUA mixtures by the influence of both heating rate and ultrasound on the Ni + Al interaction pathway for the mechano-activated (1, 3, 5 min) and 1 wt% CNT containing mixtures was observed. The formation patterns of NiAl + Ni3Al mixture or pure NiAl phase was manifested according to the interaction mechanism (depending on solid–liquid or solid–solid state of intermediates). The effective activation energy values for the Ni + Al exothermic reactions of all studied systems were determined by the isoconversional method of Kissinger.

Plasma electrolytic oxidation of cold spray kinetically metallized CNT-Al coating on AZ91-Mg alloy: Evaluation of mechanical and surficial characteristics

The cold-spray kinetically metallized (CS) carbon nanotube-aluminum (CNT-Al) and pure Al coatings were treated using plasma electrolytic oxidation (PEO) process to obtain CNT-Al+PEO and Al+PEO duplex coatings on AZ91 Mg alloy, respectively. The phase composition, microstructure, mechanical properties, wear and corrosion resistance of the PEO ceramic coatings were studied. The results showed that the PEO ceramic coating was mainly composed of α-Al2O3 and γ-Al2O3, moreover, the small amount of CNT was also retained during the PEO process. The mechanical properties and wear resistance of the PEO ceramic coatings were significantly improved compared to the respective CS coatings. In particular, the hardness and elastic modulus of the PEO-CNT coating reached 13.9 GPa and 185.4 GPa, which were 21.0% and 23.4% higher than the respective CS coating. Moreover, the wear rate of the PEO-CNT coating was only 4.83 × 10−5 mm3/N·m with a relatively low coefficient of friction of 0.65, which were 59.8% and 15.6% lower than the corresponding CS coating. The corrosion current density of the PEO-treated CNT-Al coating was 3.734 × 10−6A/cm2, which was similar to the untreated CS coating. In short, the PEO treatment greatly improves the mechanical properties and wear resistance of the CS CNT-Al coating.

Microstructure, electrical conductivity, and wear behavior of aluminum-carbon nanotubes and biosynthesized silver nanoparticles composites

Low-cost biosynthesized silver nanoparticles (GAgNPs) were used to enhance the properties of Al-carbon nanotube (CNTs) composites. Al-x% CNTs (× =0, 1, 2, 3, 4) and Al-x% CNTs (× =0, 1, 2, 3, 4) with 2%GAgNPs were produced using high intensive ball milling and spark plasma sintering. The densification, electrical conductivity, microstructure, hardness values, and wear rate were determined. The balling milling of the powders and the SPS method used in the production of the nanocomposites help to close the micro-voids in the materials with high values of densification. Higher dislocation density was obtained for the Al-4%CNTs+2%GAgNPs nanocomposites. A 7.8% and 93.11% raise in the electrical conductivity was obtained for Al, Al-4%CNTs, and Al-4%CNTs-2%GAgNPs composites. It can be concluded that the wear behavior of the Al-CNTs-GAgNPs nanocomposites was affected by the good densification of the composites, homogenous distribution of the reinforcement, and hardness values of the nanocomposites. It was established that a lower coefficient of friction and wear rate with higher electrical conductivity can be obtained with the developed Al-CNTs+GAgNPs nanocomposites.

Further, Wear and Hardness strength of the establishment medium Al6061 compound is improved with the gathering of CNT.

Effect of Shortening Carbon Nanotubes on Carbon Nanotube Dispersion, Damage and Mechanical Behavior of Carbon Nanotube-Metal Matrix Nanocomposites

Carbon nanotube dispersion in metallic matrices has been a challenge for many years. This paper investigates for the first time whether shortened carbon nanotubes as a starting material could promote improved carbon nanotube dispersion and promote less carbon nanotube damage when dispersed in metals. Aluminum-carbon nanotube nanocomposites were prepared using two carbon nanotube lengths (644nm and 10–30 μm). The nanocomposites prepared with shortened carbon nanotubes showed less carbon nanotube damage, higher microhardness, smaller matrix grain size, and improved dispersion of the carbon nanotubes as compared to the nanocomposites prepared with longer carbon nanotubes. Results suggest major implications for the use of even shorter carbon nanotubes for metal matrix composites.

A novel aluminum-carbon nanotubes nanocomposite with doubled strength and preserved electrical conductivity

Enhancing the mechanical strength of highly conductive pure metals usually causes significant reduction in their electrical conductivity. For example, introducing phase/matrix interfaces or more grain boundaries, are common and effective methods to strengthen metals. But it simultaneously increases the electron scattering at the interface, thus reducing the electrical conductivity. In this study, we demonstrate that pure aluminum (Al)/carbon nanotubes (CNTs) nanocomposites prepared by friction stir processing have successfully broken through these limitations. The yield strength and tensile strength of Al/CNTs nanocomposites have improved by 104.7% and 51.8% compared to pure Al, while the electrical conductivity remained comparable to that of pure Al. To explore the potential mechanisms, the interface between CNTs and Al was examined and characterized by transmission electron microscopy (TEM) and Raman spectroscopy. Little interfacial reaction compounds were present and no visible physical gaps were observed at CNTs and Al interfaces. We defined it as a clean and tightly bonded interface. Although the quantity of phase interface has increased, the electrical conductivity of the nanocomposite remains approximately unchanged. We attribute the preserved electrical conductivity to the clean and tightly bonded CNTs/Al interface in the nanocomposite.

Carbon nanotube-incorporated alumina as a support for MoNi catalysts for the efficient hydrodesulfurization of thiophenes

Alumina-carbon nanotubes (AlCNTs) were prepared as a support and loaded with MoNi catalyst (AlCNTMoNi). The same catalyst without the carbon nanotubes (CNTs) was also prepared to investigate their role. Techniques including N2 physisorption analysis, temperature programmed analysis, X-ray diffraction and scanning electron microscopy were used for characterization. The BET surface areas of the AlMoNi and AlCNTMoNi were 165 and 214 m2/g, respectively, while the total acidity was 0.36 and 1.53 mmol/g, respectively. The catalysts were investigated for their performance in the hydrodesulfurization (HDS) of dibenzothiophene in fuels in a batch reactor. The fuel used consisted of decalin with 550 ppm S. DBT conversions of 99% and 87% were achieved using the AlCNTMoNi and AlMoNi catalysts, respectively. The AlCNTMoNi catalyst also showed better performance than the control samples without CNTs, and physically mixed AlMoNi and AlCNTMoNi were used for comparison. The results indicate that adding CNTs into the γ-Al2O3 support enhanced the catalytic activity towards HDS due to its textural properties and surface morphology. Interestingly, the AlCNTMoNi catalyst showed excellent stability for up to five cycles, which indicates its suitability for industrial applications.

Mechanical, tribological and corrosion physiognomies of CNT-Al metal matrix composite (MMC) coatings deposited by cold gas dynamic spray (CGDS) process

A 1 wt% carbon nanotube‑aluminum (CNT-Al) metal matrix composite (MMC) powder was prepared using a polymer pyrolysis chemical vapor deposition (PP-CVD) coupled high energy ball milling (HEBM) method and the resultant MMC powder was spray deposited as a protective coating on the surface of AZ91 Mg alloy by the cold gas dynamic spray (CGDS) process. The coating microstructure, phase composition, mechanical properties, corrosion, and dry sliding wear (tribological) resistances were compared to the properties of CGDS pure Al coating. The results show that the coatings prepared by CGDS has not undergone any stoichiometric change and CNT as well as Al4C3 phases that were originally present in the CNT-Al feed-stock powder were well preserved in the resultant MMC coatings. In addition, the number and size of the pores in the CNT-Al MMC coating are significantly lower than that of the pure Al coating. The average hardness and elastic modulus of the CNT-Al MMC coating were 1.66 GPa and 77.6 GPa, which were 112.8% and 11.7% higher than those of the pure Al coating, respectively. The corrosion current density and wear rate of the CNT-Al MMC coating were 2.030 × 10−6 A/cm2 and 9.34 × 10−4 mm3/N·m respectively, which were one order of magnitude lower compared to the pure Al coating, highlighting the excellent corrosion and wear resistance of CNT-Al MMC coating.

A molecular dynamics investigation for predicting the effect of various parameters on the mechanical properties of carbon nanotube-reinforced aluminum nanocomposites.

Carbon nanotube (CNT)-reinforced aluminum (Al) composites are being developed to replace the conventional materials due to the enhanced stiffness for more cost-effective engineering applications. In the present study, a qualitative analysis has been conducted on carbon nanotube aluminum (CNT-Al) composites to predict the effect of CNT volume fraction, diameter, and structure (zigzag, armchair) on elastic modulus, shear modulus, bulk modulus, and ultimate tensile strength (UTS) through molecular dynamics simulation. This study shows that the elastic modulus was improved by 105% compared with pure Al, for the CNT-Al composite reinforced with the (4, 4) armchair SWCNT at a volume fraction of 8.79%. The highest value of Young's modulus of 130.37GPa occurred at the volume fraction of 11.75% for zigzag SWCNT. The CNT-Al composites showed better UTS for the Al matrix reinforced with larger diameter CNT. An enhancement of 31.65% was observed in the UTS of CNT-Al composite from 4.74 to 6.24GPa with (6, 6) CNT at 0.51% volume fraction. Elastic and bulk moduli were found to improve with a higher volume fraction of CNTs. The CNT-Al composite reinforced with smaller diameter CNT's have better elastic modulus than those reinforced with larger diameter CNT for the same volume fraction.

Mapping of Wear Mechanism for Mechanical Alloyed Aluminum Carbon Nanotube Composites—An In Situ Analysis

AbstractThis research work investigates the root causes of wear on the tribo surface of mechanically alloyed Aluminum/CNT composite through a simulated in situ analysis. The wear maps are developed using the second-order polynomial regression equation for the Aluminum/CNT composite to discriminate the wear mechanisms at different levels of their influencing factors and milling parameters. As a result, the predominant wear mechanism is identified as surface fatigue for Aluminum/CNT composite under high loading dry sliding condition. This study also reveals the modes for eliminating the severe wear at the tribo-surfaces. Aluminum/CNT1 wt% composite fabricated with the mechanical alloying parameters above 6 h of milling time and above 5 rps of milling speed eliminates the delamination under low level of tribological parameters, and it achieves the minimal wear-rate of 30.5 × 10−6 g/m and coefficient of friction (CoF) of 0.346.

Porous Al2O3-CNT Nanocomposite Membrane Produced by Spark Plasma Sintering with Tailored Microstructure and Properties for Water Treatment.

Ceramic-based nanocomposite membranes are gaining great attention in various applications, such as water treatment; gas separation; oil and gas, amid their superior fouling resistance and remarkable chemical/thermal stability. Here, we report for the first time the use of spark plasma sintering (SPS) process to fabricate a porous alumina–carbon nanotubes (Al2O3–CNT) nanocomposite membrane for water treatment. The challenge is this work is to achieve a balance between the amount of porosity, desired for a high water flux, and the membrane strength level, required to resist the applied pressure during a water flow experiment. The effect of SPS process parameters (pressure, temperature, heating rate, and holding time) on the microstructure and properties of the developed membrane was investigated and correlated. A powder mixture composed of Al2O3 and 5 wt % CNT was prepared with the addition of starch as a pore former and gum Arabic and sodium dodecyl sulfate as dispersants. The powder mixture was then sintered using SPS to produce a solid but porous nanocomposite membrane. The structure and microstructure of the developed membrane were characterized using X-ray diffraction and field emission scanning electron microscopy. The performance of the membrane was assessed in terms of porosity, permeability, and mechanical properties. Moreover, the adsorption capability of the membrane was performed by evaluating its removal efficacy for cadmium (II) from water. The microstructural analysis revealed that CNT were distributed within the alumina matrix and located mainly along the grain boundaries. The permeability and strength were highly influenced by the sintering pressure and temperature, respectively. The results indicated that the membrane sintered at a pressure of 10 MPa, temperature of 1100 °C, holding time of 5 min, and heating rate of 200 °C/min exhibited the best combination of permeability and strength. This developed membrane showed a significant removal efficiency of 97% for cadmium (II) in an aqueous solution.

In-situ observation of interaction between dislocations and carbon nanotubes in aluminum at elevated temperatures

In this study, in-situ high-temperature transmission electronic microscopy is performed to investigate the formation mechanism of high-fraction (>50%) low-angle grain boundaries (LAGBs) in carbon nanotubes/aluminum (CNTs/Al) composites with balanced strength and ductility. During heating up the low-temperature-sintered composite, we find that dislocation bands first moves and then they are pinned by CNTs to form LAGBs. Abundant dislocations in the Al matrix and large-aspect-ratio CNTs are clarified as two critical factors for producing LAGBs. This study provides new insight into the effect of CNTs on the microstructural and mechanical properties of metal matrix composites.

Effect of Different Raw Material Property for the Fabrication on Al/CNT Nanocomposite Using a Ball Mill with a Discrete Element Method (DEM) Simulation.

Carbon nanotubes (CNTs) have received interest as an attractive reinforcing agent metal matrix composites regarded as an increase to mechanical properties of the final product. Aluminum/carbon nanotubes (Al/CNTs) nanocomposites were observed with different raw material at the optimized experimental condition. In this study, Al-based CNTs composites were three different samples, including un-milled Al, un-milled Al with CNTs, and milled Al with CNTs nanocomposites in the presence of additional CNTs with various experimental conditions while using a traditional ball mill (TBM). The particle morphology and CNT dispersions of milled composites were respectively analysed by scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM), and the mechanical properties of the fabricated composites were tested. In each sample, CNTs were well dispersed on the surface of Al powder at different experimental conditions for milling in a TBM. The Al/CNTs nanocomposites were processed by compacting, sintering and rolling process. The Vickers hardness was used to characterize the mechanical properties. The hardness of Al/CNTs nanocomposites that were fabricated with milled Al with CNT was higher than the reached to in the nanocomposites prepared with the use of un-milled Al with CNT nanocomposites. Therefore, the discrete element method (DEM) simulation was used to complete quantitative analysis. The flow pattern, impact force, and energy at various experimental conditions are considered. The results of the simulations are compared with experimental data.
