Abstract

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.
