Machining performance of Nano SiC and graphite powder mixed aluminum matrix composites fabricated by powder metallurgy using EDM

Currently, aluminum MMCs are increasingly being used for different engineering applications due to their lot advantages. In this experiment, MMCs were machined using electrical discharge machining (EDM) to get high-performance results. Powder Metallurgy method was used to add different percentages of Graphite (3 %, 5 % & 7 %) and Silicon Carbide (5 %, 10 % & 15 %) Nano-powders to pure Aluminum powders. Different Compaction loads and Sintering temperatures were taken at 150, 200 & 250 KN, and 500, 550 & 600 °C respectively. The process parameters have been designed using the Taguchi L9 orthogonal array. With input parameters such as current (I), pulse on time (Ton), pulse off time (Toff), and voltage, the EDM technique was chosen for machining composite materials. The addition of silicon carbide particulates with aluminum metal matrix increases the Surface Roughness (Ra) and Hardness but decreases the Metal removal rate (MRR), and a suitable amount of graphite particulates with aluminum metal matrix increases MRR, SR, and Hardness also of the composite material. The Taguchi technique is used to assess the best P/M process parameter setting for a given signal-to-noise (S/N) ratio order.

Deformation behavior of graphite and its effect on microstructure and thermal properties of aluminum/graphite composites

Al/graphite composites were prepared by spark plasma sintering (SPS) and hot extrusion (HE). Two kinds of extrusion routes (with and without 90˚ rotation of the extrusion billets) were used to understand the deformation behavior of graphite during extrusion process. Microstructure, thermal conductivity (TC), and coefficient of thermal expansion (CTE) of the SPSed and HEed samples were investigated. Microstructural observations showed that HE can lead to deformation, exfoliation, and breakage of graphite. The shear deformation caused preferential distributions of graphite along the extrusion direction. The exfoliation degree of graphite in the HEed sample with rotation was much higher than that in the HEed sample without rotation, thus resulting in more Al/graphite interfaces and smaller Al grains, which inhibited heat transfer in Al/graphite composites. Both graphite deformation and strong interfacial bonding between graphite and Al matrix resulted in decreases in average interlayer spacing d002 of graphite. The Al/graphite interfaces in the HEed samples were relatively intricate, and amorphous-like carbon, more defects, and cleavage facets were observed in the severely deformed graphite in the HEed sample without rotation. The HEed sample without rotation showed the higher TC and lower CTE. The higher TC is attributed to the decrease in average interlayer spacing d002 of graphite, while lower CTE is associated with the intricate Al/graphite interfaces. These findings can provide new insights for preparing metal matrix/graphite composites with high TC and low CTE.

Glucose Incorporated Graphite Matrix for Electroanalysis of Trimethoprim.

The antibiotic drug trimethoprim (TMP) is used to treat bacterial infections in humans and animals, and frequently TMP is used along with sulfonamides. However, a large portion of TMP is excreted in its active state, which poses a severe problem to humans and the environment. A sensitive, rapid, cost-effective analytical tool is required to monitor the TMP concentration in biological and environmental samples. Hence, this study proposed an analytical methodology to analyze TMP in clinical, biological and environmental samples. The investigations were carried out using a glucose-modified carbon paste electrode (G-CPE) employing voltammetric techniques. Electrochemical behavior was examined with 0.5 mM TMP solution at optimum pH 3.4 (Phosphate Buffer Solution, I = 0.2 M). The influence of scan rate on the electro-oxidation of TMP was studied within the range of 0.05 to 0.55 V/s. The effect of pH and scan rate variations revealed proton transfer during oxidation. Moreover, diffusion phenomena governed the irreversibility of the electrode reaction. A probable and suitable electrode interaction and reaction mechanism was proposed for the electrochemical oxidation of TMP. Further, the TMP was quantitatively estimated with the differential pulse voltammetry (DPV) technique in the concentration range from 9.0 × 10−7 to 1.0 × 10−4 M. The tablet, spiked water and urine analysis demonstrated that the selected method and developed electrode were rapid, simple, sensitive, and cost-effective.

Fracture behavior analysis of brittle graphite sphere using a special bond model

High-Temperature Reactor–Pebble-bed Module (HTR-PM) takes the spherical fuel element design. Failure or not of fuel sphere would highly affect system operation and nuclear safety. Crush strength of fuel sphere is an important quality control measure, which is mainly determined by the graphite matrix. A bonded particle model (BPM) from discrete element method (DEM) is disclosed, validated, and applied in the fracture analysis of brittle graphite sphere. On the basis of validated BPM, the breakage behavior of nuclear fuel sphere under high-speed impact, that is, dynamic loading, is revealed in detail by a time-marching numerical simulation. This meshfree particle method can be effectively extended to the failure computation of different composite structures (e.g., particle-reinforced metal matrix composite) by defining heterogeneous bonds inside distinct material interface.

Amorphous carbon engineering of hierarchical carbonaceous nanocomposites toward boosted dielectric polarization for electromagnetic wave absorption

Graphitic carbon materials are considered to be an important category of dielectric absorbers, but these materials are typically accompanied with poor impedance matching and unsatisfactory electromagnetic wave absorption (EMA) performance. Herein, engineered amorphous carbon is developed to produce hierarchical carbonaceous nanocomposites (HCNs) via crystallization-induced interfacial polymer self-assembly and carbonization, which is aimed at boosting dielectric polarization for enhancing EMA capability. By optimizing the polymer precursor species, graphitic carbon matrix, and carbonization temperature, the hierarchical architecture and N-bonding configurations, containing pyridinic N, pyrrolic N, and graphitic N, can be regulated for polarization relaxation loss and conductive loss. In addition, multiple reflection and scattering behavior are also beneficial for increasing EMA capability. Compared with those of the pure graphitic carbon matrix and related HCNs, the minimum reflection loss (RLmin) of MWCNTs coated with polyimide-derived amorphous carbon at 700 °C (MWCNT/C(PI-EDA)-700) is −45.7 dB at a matched thickness of 3.6 mm with a filler loading of only 5 wt%, and its effective absorption bandwidth (EAB, RLmin < −10 dB) is 3.9 GHz. In summary, based on the systematic analysis of 16 carbonaceous absorbers, in this study, not only the intrinsic EMA mechanism of HCNs is revealed, but also new avenues for designing and fabricating high-efficiency dielectric absorbers are opened.

Improvement of heat sink performance using paraffin/graphite/hydrogel phase change composite coating

Phase-change materials offer high latent heat and are widely used for energy storage applications. Paraffin wax is usually used as a phase-change material. However, its application in energy storage is restricted due to its low thermal conductivity. In the present work, graphite and graphite-hydrogel are used to enhance the thermal conductivity and heat release properties of paraffin wax. Wax-graphite (W-G) and wax-graphite-hydrogel (W-G-H) composites were synthesized by the dispersion of graphite and graphite-hydrogel in paraffin wax above its melting temperature. Scanning electron microscope (SEM) analysis was used to investigate the graphite and graphite-hydrogel distribution in the paraffin wax matrix. Thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) characterization were performed to measure the thermal stability and phase transition properties, respectively. DSC revealed that all composites have a similar melting temperature. The W-G-H composite displayed nearly 12 folds more thermal conductivity compared to the pure paraffin wax. High temperature brings adverse impacts on energy efficiency, and even destroys a semiconductor device. The synthesized W-G-H composite is proposed to decrease the working temperature of semiconductor devices. As an applicative demonstration, the W-G-H composite film was coated at the back of the solar panel. The W-G-H composite coated solar panel displayed a surface temperature that was near ∼4 °C lower than the bare solar panel while operating. The real-time experiment indicates that the W-G-H composite has high thermal conductivity and heat release properties. The study reports fundamentally new low-cost, simple, scalable, and self-adaptive, passive cooling technology to the semiconductor industry. The proposed material can further be developed in the form of paint and its heat sink properties can be improved by introducing hydrogels doped with Li+ and Br− ions.

Low-friction, wear-protecting coatings on polymers by atmospheric pressure plasma spraying

Deposition strategies to obtain low-friction and wear resistant coatings on 3D-printed rough polyamide 12 (PA12, nylon) surfaces were developed via atmospheric pressure plasma deposition. The feedstock materials for the DC plasma torch InoCoat 3 produced by INOCON Technologie GmbH were dry lubricants such as MoS2 and graphite. In addition, parameter sets that would not thermally damage the heat sensitive polymers were applied. Generally, microtribological characterisation indicates that coating composition and thickness particularly influence the coating performance significantly. Pure MoS2 coatings wear rapidly, particularly on the roughness tips (mean substrate roughness Ra up to 20 μm); this exposes the substrate and leads to friction coefficients similar to those of PA12 and rather limited potential for protection against wear. Composite coatings with graphite in a MoS2 matrix provide huge potential for wear protection (i.e. >20 times less penetration depth) even for exposed PA12 roughness tips, owing to the transfer of lubricating carbon into these exposed areas. If the thickness is sufficiently high, preventing the wear of tips results in low-friction properties (friction coefficients < 0.1, i.e. four times lower than those for uncoated PA12).

Phase change materials for battery thermal management of electric and hybrid vehicles: A review

Battery is essential parts of an electric and hybrid electric vehicle. Good amount of heat is generated by charging and discharging actions. For maximum efficiency, reliability of utmost necessary to conserve the optimum temperature by employing a proper battery thermal management system.

Additionally, a thermal management system merging Phase Change Material cooling via air or liquid is also presented.

Highly active nitrogen – doped carbon nanostructures as electrocatalysts for bromine evolution reaction: A combined experimental and DFT study

Electrocatalytic bromine evolution reaction (BER) is significant for bromine production, energy storage, and wastewater treatment applications. Previously reported electrocatalysts for BER either include unstable graphite anodes or precious metal-containing materials. To overcome their disadvantages, this work has proposed, for the first time, the use of nitrogen-doped carbon nanostructures (CNx) as anode catalysts for BER in acidic medium. In terms of BER activity, CNx outperforms both Vulcan Carbon and commercial 10 % Pt/C at bromide concentration as low as 0.025 M. CNx also exhibits high BER selectivity and remarkable stability at highly oxidizing potentials. Tafel slope was measured to be ∼ 120 mV/dec supporting a first electron transfer limiting step for BER on CNx. The high activity and stability of CNx is attributed to several nitrogen-doped carbon sites in its graphitic matrix, which have been examined using DFT. The inclusion of oxygen evolution reaction (OER) intermediates is critical to identify BER active sites accurately, as the most active sites (zigzag pyridinic, zigzag oxide, and pyrrolic oxide) proceed via a OH*-mediated Volmer-Heyrovsky mechanism. For these sites, DFT predicts that the potential determining step is the first electron transfer to form Br* in agreement with the experimental Tafel slope. Comparison to post-reaction XPS shows good agreement between DFT predicted Br* structures. This work thus provides a direction for the rational design of CNx electrocatalysts for BER.

Carbon matrix with atomic dispersion of binary cobalt/iron-N sites as efficient peroxymonosulfate activator for organic pollutant oxidation

Monometallic single atom catalysts have exhibited excellent catalytic capacity due to their unique structural features. However, it remains challenging to promote the limited number of active sites and realize high-efficiency and stability during Fenton-like catalysis. Herein, a nitrogenized graphitic carbon matrix containing Fe-Co dual single atoms (FeCoNC) manifested enhanced catalytic capacity in persulfate activation for tetracycline hydrochloride (TC) oxidation. Nonradical singlet oxygen (1O2) was identified as dominant reactive species in both FeCoNC and CoNC systems, while the formation pathways of 1O2 and TC catalysis processes were distinct different. 57Fe Mössbauer spectroscopy and theoretical calculations revealed that the dynamic electronic structure and covalency of Fe-N/Co-N bond configuration after coordinating with a second neighboring metal atom induced promoted electron transfer and tuned reactive species transformation pathways. Benefiting from the optimized N3-Fe-Co-N3 structure and synergistic effect of dual metal sites, the FeCoNC catalyst was endowed with lowered reaction barriers, excellent adaptability and stability, demonstrating promising practical application potential. This work unveiled the intrinsically regulated mechanism of dual single metal sites towards refractory organic oxidation and delivered enhanced understanding of covalency and electronic configuration on PMS-AOPs based catalysis processes.

Tuning the Surface Characteristics and Mechanical Properties of Y2O3 Coatings on a Graphene Matrix via Laser Micro Melting.

The effects of laser parameters on the microstructure and properties of plasma-sprayed yttrium oxide coating on the graphite matrix were investigated. Tensile strength, porosity, roughness, and scratch meter tests were carried out to evaluate the critical load and mechanical properties of the coating after spraying and laser micro-melting. When the porosity and surface roughness of the coating are minimum, the critical load of the coating is 7.85 N higher than that of the spraying surface. After laser micromelting, the crystal phase of Y2O3 coating surface does not change, the crystallinity is improved, and fine grain strengthening occurs. When the laser power density is 75 W/mm2, the scanning speed is 30 mm/s, and the defocusing distance is 40 mm, the film base bonding performance and wear resistance of the material reach the maximum value. The failure of Y2O3 coating is mainly due to the degradation of mechanical properties such as film base bonding strength, surface porosity, and surface roughness, which leads to the local collapse of the material. The coating after laser micro-melting only presents particle disintegration at the end of the scratch area.

Experimental determination of crystallization kinetic model of CENG-PCM composite material. Validation at macro and meso scales

• Two different crystallization mechanisms are observed in the PCM. • A visualization experiment is performed for morphological identification. • Crystallisation kinetic modelling is carried out by using Nakamura kinetics models. • The crystallisation kinetic model is validated at micro and macro scales. This article presents a method for modelling the crystallisation kinetic of a phase change composite material when two transformations occur during the solidification. To obtain the full description of the crystallization process, the DSC analysis was completed with visualisations and extrapolations based on physical and analytical assumptions. This method has been validated successfully at different scales with paraffin and with paraffin embedded in Compressed Expanded Natural Graphite (CENG) matrix. The phase change material studied was a paraffin RT70HC from Rubitherm®. The validation experimental cases were performed on a plate of CENG-RT70HC composite cooled from its side and a packed-bed heat storage exchanger with a filler composed with encapsulated CENG-RT70HC capsules. The kinetic model was implemented in the finite element code Comsol® adding a source term to the energy equation. This model simulated closely the temperature evolution of a phase change material during a cooling. We found that the crystallisation kinetic is the same for the paraffin and for the paraffin with CENG showing that the CENG do not apparently affect the kinetic crystallisation of the paraffin.

Effect of soft-mould pressing method on anisotropy of the graphitic matrix spheres: Dry-bag isostatic vs. Quasi-isostatic

The anisotropy of graphitic matrix in fuel elements for high-temperature gas-cooled reactors (HTR) has an important effect on the distribution of thermal stress and irradiation stress, which should be strictly controlled. In this study, the graphitic matrix spheres were prepared through quasi-isostatic pressing and dry-bag isostatic pressing. The anisotropy was compared from the elastic modulus, crushing load, coefficient of thermal expansion (CTE) and thermal conductivity in different directions. The causes of anisotropy were investigated from the aspects of raw material microstructure, charging, pressing, as well as heat treatment. The graphite microstructure and the preferred orientation of graphite particles in the production process were found as the main reasons for the anisotropy of thermal and mechanical properties. The dry-bag isostatic pressing method can effectively reduce anisotropy and increase the production capacity compared with the quasi-isostatic method, which is consistent with the development trends of high quality and low cost fuel elements.

Camphene-derived hollow and porous nanofibers decorated with hollow NiO nanospheres and graphitic carbon as anodes for efficient lithium-ion storage

A synthesis strategy for hollow and porous nanofibers comprising hollow NiO (H-NiO) nanospheres formed via nanoscale Kirkendall diffusion and supported over a porous graphitic carbon matrix (H-NiO@HNFs) is reported herein to enable the fabrication of advanced anodes for stable lithium-ion batteries (LIBs). The H-NiO@HNFs comprising 1D longitudinal hollow channels ensured efficient diffusion of charged species via effective electrolyte percolation besides providing sufficient space to accommodate the large volume variations during repeated cycling. The hollow NiO nanospheres acted as chemical sites for lithiation and delithiation. Additionally, the H-NiO@HNFs exhibited improved lithium-ion storage properties, such as reasonable rate capability, stable prolonged cyclability at a high current density (1.0 A g-1), and a high lithium-ion diffusion coefficient, primarily owing to their enhanced structural integrity compared to that of filled NiO nanofibers (F-NiO NFs). This facile synthesis approach could broaden the current understanding of 1D hollow nanostructures decorated with conventional hollow metal-oxide nanoparticles for various applications.

Adsorptive capacity of a g-C3N4 matrix for thiamethoxam removal: A DFT study

In this study, the adsorptive capacity of the insecticide thiamethoxam (TMX) on a graphitic carbon nitride matrix (g-C3N4) was studied theoretically. Two adsorbent-adsorbate complexes, g-C3N4-TMX1 and g-C3N4-TMX2 was formed through hydrogen bonds (HB) and the the hydrogen bonds lengths ranging from 2.610 Å to 3.538 Å. Topological analyses based on the quantum theory of atoms in molecules confirmed the bond critical points of hydrogen bonds. Further, it allowed for the classification of the HBs as weak, with hydrogen bond energy values ranging from −0.98 to −6.58 kJ mol−1. Calculations of the energies involved in the processes proved that the interaction of TMX with the g-C3N4 matrix occurs in two sites with values of ΔEBind = −71.65 kJ mol−1 and ΔEBind = −70.44 kJ mol−1, sites 1 and 2, respectively. The results showed that the interaction is is spontaneous and exothermic, as indicated by the negative values of ΔG and ΔH.

Efficient Visible-Light Photocatalysis and Antibacterial Activity of TiO2-Fe3C-Fe-Fe3O4/Graphitic Carbon Composites Fabricated by Catalytic Graphitization of Sucrose Using Natural Ilmenite.

Dyes in wastewater are a serious problem that needs to be resolved. Adsorption coupled photocatalysis is an innovative technique used to remove dyes from contaminated water. Novel composites of TiO2-Fe3C-Fe-Fe3O4 dispersed on graphitic carbon were fabricated using natural ilmenite sand as the source of iron and titanium, and sucrose as the carbon source, which were available at no cost. Synthesized composites were characterized by X-ray diffractometry (XRD), Raman spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray fluorescence spectroscopy (XRF), and diffuse reflectance UV–visible spectroscopy (DRS). Arrangement of nanoribbons of graphitic carbon with respect to the nanomaterials was observed in TEM images, revealing the occurrence of catalytic graphitization. Variations in the intensity ratio (ID/IG), La and LD, calculated from data obtained from Raman spectroscopy suggested that the level of graphitization increased with an increased loading of the catalysts. SEM images show the immobilization of nanoplate microballs and nanoparticles on the graphitic carbon matrix. The catalyst surface consists of Fe3+ and Ti4+ as the metal species, with V, Mn, and Zr being the main impurities. According to DRS spectra, the synthesized composites absorb light in the visible region efficiently. Fabricated composites effectively adsorb methylene blue via π–π interactions, with the absorption capacities ranging from 21.18 to 45.87 mg/g. They were effective in photodegrading methylene blue under sunlight, where the rate constants varied in the 0.003–0.007 min–1 range. Photogenerated electrons produced by photocatalysts captured by graphitic carbon produce O2•– radicals, while holes generate OH• radicals, which effectively degrade methylene blue molecules. TiO2-Fe3C-Fe-Fe3O4/graphitic carbon composites inhibited the growth of Escherichia coli (69%) and Staphylococcus aureus (92%) under visible light. Synthesized novel composites using natural materials comprise an ecofriendly, cost-effective solution to remove dyes, and they were effective in inhibiting the growth of Gram-negative and Gram-positive bacteria.

N-doped graphitic carbon encapsulated cobalt oxide nanoparticles from ZIF-67 on ZIF-8 as an anode material for Li-ion batteries

Recently, cobalt (II, III) oxide (Co 3 O 4 ) is considered as an alternative anode material for high-performance LIBs because of its high safety and theoretical capacity (890 mAh g −1 ). However, Co 3 O 4 anode materials suffer from low conductivity and poor cycle life due to structural strain and huge volume change during lithiation/delithiation processes. In this work, porous N-doped graphitic carbon encapsulated Co 3 O 4 structure (Co 3 O 4 @PNGC) was synthesized by using mixed Zn and Co metal-organic frameworks templates (ZIF-67/ZIF-8) and coated with polydopamine as a nitrogen and carbon source. During the synthesis, Zn species was evaporated to form the structural pores, and the in-situ formation of Co(0) occurred that served as a catalyst in the graphitization of the carbon matrix. The Co 3 O 4 /PNGC exhibited an improved discharge capacity of 847.4 mAh g −1 after 500 cycles at 1 C when compared to the bare sample. • Co 3 O 4 @PNGC was prepared from cuboidal ZIF-67 @ZIF-8 particles wrapped by PDA via a facile method. • The unique PNGC structure can prevent undesirable Co 3 O 4 growth and enhance electrical conductivity of electrodes. • Co 3 O 4 @PNGC sample exhibits significantly improved electrochemical performances.

Ductile Cast Iron 350/4 using SMAW

Abstract: This article examines the weldability of ductile cast iron when the root weld is applied with a tungsten inert gas (TIG) welding process employing an Inconel 625 source rod, and when thefiller welds are applied with electrodes coated with 97.6% Ni. The welds were performed on ductile cast iron specimen test plates sized 300 mm × 90 mm × 10 mm with edges tapered at angles of 60◦ . The plates were subjected to two heat treatments. This article analyzes the influence on weldabilityof the various types of electrodes and the effect of preheat treatments. Finally, a microstructure analysis is made of the material next to the weld in the metal-weld interface and in the weld itself. The microstructure produced is correlated with the strength of the welds. We treat an alloy with 97.6% Ni, which prevents the formation of carbides. With a heat treatment at 900 ◦C and 97.6% Ni,there is a dissolution of all carbides, forming nodules in ferritic matrix graphite.

Nanostructural glass composite coatings

The results of the study of glass-composite nanostructured self-lubricating coatings are presented. The developed glass composite is an antifriction material with an ultrafine structure. The structural components of these coatings significantly affect the graphitization process and provide an antifriction surface layer of α-graphite. The formation of this layer makes it possible to significantly minimize the contact parameters in the friction region.&#x0D; The developed antifriction nanostructured glass-ceramic self-lubricating coatings containing magnesium carbide and structural components that promote surface graphitization do not contain expensive and scarce components, meet environmental safety requirements, and have high performance characteristics. A significant effect of aluminoborosilicate in the form of a glass phase on the tribological properties of coatings is noted. An increase in adhesive strength is achieved by forming a surface layer of glassy sodium silicate. Using X-ray phase analysis, it was found that the intercalating elements in the subsurface zone-graphite system at the initial stage of the process were Mg2+, Al3+, Cu2+ ions, which randomly penetrated into the interlayer space of the graphite matrix. At sliding speeds of more than 3.0 m/s, intercalates of binary molecular compounds of these elements with oxygen were found in the layered system of graphite. Their intercalation is accompanied by a sequence of repetitive stages, which are reversible with a change in tribological parameters and are characterized by a specific transformation of the structure and, above all, by an increase in the distance between layers due to the influence of various types of interlayer defects and the introduction of intercalants.&#x0D; The presence of near-surface particles in the graphite layer does not affect the tribotechnical characteristics of the coatings. The developed glass-composite nanostructured self-lubricating coatings have high antifriction characteristics throughout the entire load-speed range

Evaluation of Mechanical and Tribological Aspect of Self-Lubricating Cu-6Gr Composites Reinforced with SiC–WC Hybrid Particles

Because of their high thermal conductivity, good corrosion resistance, and great mechanical qualities, copper matrix composites are appealing materials utilized in a variety of industries. This study investigates the mechanical properties of copper–graphite (Cu–Gr) matrix composites reinforced with silicon carbide (SiC) and tungsten carbide (WC) particles by hot pressing using powder metallurgy method. The goal is to investigate the influence of the reinforcement ratio on the mechanical characteristics of copper composite materials generated (density, hardness, flexural strength, and wear resistance). SEM, EDS, and X-RD analysis were used to perform metallographic examinations. The highest relative density with a value of 98.558% was determined in the C3 sample. The findings revealed that when the reinforcement ratio was raised, the hardness rose. The highest hardness value was observed in the C6 sample with an increase of 12.52%. Sample C4 (with the lowest SiC and WC particles ratio) had the highest bending stress (233.18 MPa). Bending stress increased by 35.56% compared to the C1 sample. The lowest specific wear rates were found in the C4 sample, with a decrease of 82.57% compared to the C1 sample. The lowest wear rate (6.853 × 10−7 mm3/Nm) also occurred in the C4 sample. The microstructural analysis showed that the hybrid reinforcement particles exhibited a homogeneous distribution in the copper matrix. X-RD analysis showed that there was no intermediate reaction between the parent matrix and the hybrid reinforcements. A good interfacial bond was observed between the matrix structure and the hybrid reinforcements. The motivation of this research was to utilise the advantages of the unique features of SiC–WC hybrid particles to improve the performance of newly developed Cu-6Gr composites for wear-resistance applications.
