Effect of sic content on dry sliding wear behavior of nanosized SIC(P)‎-Cu composites

Abstract EN

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.
