Abstract
The wear behavior of an aluminosilicate (Al2O3. SiO2) short-fiber-reinforce d Al-12Si alloy composite and the parent Al-12Si alloy were investigated un der dry conditions. The results show that the increased wear resistance of Al2O3. SiO2/Al-12Si can be attributed to the formation of a hardened layer in the sub-surface region where realignment and redistribution of fragmente d eutectic phase and fragmented aluminosilicate fibers occur during dry sli ding.
