Abstract

In this investigation of surface hybrid composites on aluminium alloy 7075 substrate using friction stir processing (FSP) with various composition of reinforced particles such as silicon carbide (SiC) and graphite (Gr). The distribution of reinforcement in the nugget zone was examined by SEM with EDS analysis. The strength and microhardness are compared with the samples. Sample S3 (50% SiC + 50% Gr) shows the property superior than other combinations. The samples with higher amount of graphite content leads to deterioration in tensile strength and hardness.
