Effect of Sic Content on Dry Sliding Wear Behavior of Nanosized Sic(p)/Cu Composites

In this study, the wear behavior of nano Cu and SiC(p)/Cu composites powders with different weight percentages of SiC particles was investigated under pin on disc equipment at 8–20 N load and 0.83-3.25 sliding speed. The composites were produced via powder metallurgy (PM) route. The results revealed that the wear resistance of SiC(p)/Cu composites increased with increasing SiC content to 20 vol %. Beyond this value the wear resistance decreased but still more than the unreinforced sample. Moreover, the investigation on worn surfaces was done to understand wear mechanism.
