Processing of Al7075 matrix composites reinforced with content (1.0 wt.%) of graphene and SiC nanoparticles (0.25-2.0 wt.%) using ball milling and vacuum hot press is reported. Near full densification was observed for all the composite compositions at the sintering temperature of 610 degrees C (time of 1.5 hand applied pressure of 50 MPa). Detailed analysis of the microstructure and mechanical and tribological properties with reinforcement content in Al7075-graphene-SiC(p)composites is presented. The results show that the graphene and SiC nanoparticles predominantly are homogeneously distributed on the grain boundaries of Al matrix and SiC nanoparticles are distributed between graphene sheets. There is a significant increase in the hardness and wear resistance and a reduction in the coefficient of friction values compared to pure Al7075 alloy.
