Sliding wear property of Al-Cu Based alloys with SiC particle reinforced Composites under varying Experimental Conditions

The article reports on the sliding wear behavior of SiC reinforced composites of Al-Cu alloy and its dependence and change with experimental parameters. Wear resistance in composites is mainly attributed to the effective resistance of the SiC particle to penetration, grinding and cutting by the ceramic particulates. When the particle sizes are small matrix strengthening of the particles as well as wear resistance of the particles contributes to improving the wear resistance. Under conditions where mild wear conditions prevail wear is generated by fracture and removal of the oxide layer which is formed in aluminum alloys as a result of continued sliding action
