چکیده
|
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.
