Abstract

The main aim of using the factorial analysis method in the present work was to investigate the influence of parameters viz.: load, sliding speed, and concentration of SiC, so also the combined interaction of these parameters on wear rates, coefficient of friction, and rise in bulk temperature. Pure copper and 10%SiC reinforced copper composites were produced by powder metallurgy route by compaction and then sintered these compact at 860 °C for 2 h in hydrogen sintering furnace. The wear test was carried out on the Cu-SiC composites. Experimental plan of wear test consisted of two load (25 and 65 N) and two sliding speeds (0.6 and 2.4 m/s) for two compositions (Pure Cu and 10 vol% of SiC in copper matrix). The wear tests were implemented on Pin-on-Disc wear test machine as per ASTM G99. Analysis of wear test data was done by 2³ factorial method. The relationship of individual and combined interactive parameters was attempted with worn surfaces and XRD in order to explore possible wear mechanisms.
