摘　　要：The present research deals with development and characterisation of magnesium–SiC–Gr hybrid composites through powder metallurgy route.Morphology analysis of the magnesium and reinforcement powder particles has been carried out using particle size analyser(PSA)and X-ray diffraction(XRD),and then the mixed powders were analysed through scanning electron microscope(SEM).The developed composite exhibit increased hardness when compared to base material,which could be attributed to the presence of hard SiC.Furthermore,a slight decrease in hardness is observed for the hybrid composite when compared to Mg–SiC composite due to the presence of soft Gr particles.The tribological properties of the developed composite materials were investigated using pin-on-disc wear test apparatus under dry sliding conditions.The wear resistance of the developed composites improved significantly than that of the magnesium matrix due to the upright effect offered by both of the reinforcements.The SEM analysis was carried out on the worn out surfaces for better understanding of wear mechanisms.5%Gr reinforced Mg-10SiC composites confer better wear resistance among the developed composites. 关键词：MAGNESIUM Hybrid composites Powder metallurgy Sliding wear
