“…The wear test was carried out using a pin-on-disk wear test machine on grounded samples with a 5 N normal load, sliding speed of 1.45 m/s with a rotational speed of 1400 r.p.m without lubrication. These parameters are chosen according to our previous work [46]. An electronic balance with a resolution of 0.1 mg was used to measure the weight of the samples before and after the test.…”

“…Moreover, incorporating hard ceramic particles into ductile materials with a uniform distribution could reduce grain size, which has a positive effect on the hardness of composites [46]. The reduction in hardness value after 10 wt% uncoated CF may occur because the hardness is affected by other detrimental factors such as aggregation and relative density reduction.…”

Poor interfacial structure and severe agglomerations of carbon fiber (CF) are significant problems that face carbon fiber reinforced aluminium (CF/Al) composites. Thus, CF was surface modified with nano copper particles (Cu) to overcome these problems. Two groups of CF/Al composites (uncoated and coated) at different weight percentages of reinforcement (0, 5, 10, 15, and 20) were fabricated using the planetary ball milling method and then uniaxially hot coined at 550 ℃ under 700 MPa. The results showed that CF refined the crystallite size of the Al matrix, and no $${\mathrm{Al}}_{4}{\mathrm{C}}_{3}$$ Al 4 C 3 or $${\mathrm{Al}}_{2}\mathrm{Cu}$$ Al 2 Cu were detected in XRD patterns. The density and thermal expansion of composites reduced with increasing CF percentage in all samples. The electrical and thermal conductivities are improved up to 10 wt% of uncoated reinforcement and 15 wt% of coated one. The mechanical test results revealed that by increasing CF, the compressive strength of composites decreased while the wear properties improved for both groups. Cu deposition on CF improved the bonding between reinforcement and matrix, producing composites with better interfacial bonding, fewer agglomerations and porosity, and higher values of the properties of the composites.

Aluminum (Al) composites have been extensively developed for automotive applications due to their high specific strength. Therefore, in this study, an Al-titanium dioxide (TiO2) nanocomposite was processed using the accumulative roll bonding (ARB) process. The mechanical characteristics of monolithic and nanocomposites specimens made with 0, 1, 2, and 3 wt% TiO2 nanoparticles as reinforcement were studied at several ARB passes. According to the microstructure of the composites, rolling after five passes achieves a homogenous distribution of reinforcement particles, ultrafine and elongated grains of the matrix. After five ARB passes, the TiO2 particles were uniformly dispersed. Finally, scanning electron microscopy and energy dispersive spectroscopy revealed that the Al-TiO2 nanocomposite had an appropriate dispersion of TiO2 nanoparticles. Vickers microhardness improves as the number of accumulative roll bonding passes increases. Furthermore, after five passes, Vickers microhardness testing revealed that the sample with 3%TiO2 has the greatest hardness value of 112 HV, which is significantly greater than the 44 HV hardness value of the ARB-processed aluminum. The mechanical properties of the specimens, yield and ultimate strengths, improved with the addition of TiO2 nanoparticles. Due to good bonding among the components, mechanical parameters such as microhardness and tensile strength were more than three times better than the Al matrix.

In this study, copper powder was reinforced with different weight percentages of Al2O3 particles (0, 5, 10, and 15 wt.% Al2O3 coated Ag) to produce Cu-Al2O3 composites by mechanical alloying and uniaxial cold pressing/sintering route. Electro-less deposition was used to coat Al2O3 particles with Ag. The microstructure of the consolidated samples was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) elemental mapping. The porosity, microhardness, and wear behavior of the consolidated samples were also investigated as a function of Al2O3 content. The EDX mapping images reveal that the Al2O3 reinforcement particles were homogeneously distributed into the Cu matrix. Microstructural analysis shows that the addition of Al2O3 coated Ag particles improves density of the composites coating. SEM micrographs result shows that slight porosities exist in the composites produced. Furthermore, the average hardness of the composite coatings varies from 72.3 to 187.6 HV as Al2O3 content increases from 0 to 15 wt.%. The wear test results showed that the composite with higher Al2O3 content 15 wt.% showed the best wear resistance.
