EFFECT OF GRAPHITE ON WEAR RESISTANCE OF ALUMINUM-SILICON ALLOY

Abstract

This research deals with studying the effect of graphite on the wear resistance of aluminum – silicon alloy. Firstly this alloy (master alloy) is prepared using casting method then graphite particles added in weight ratio (5.5 %) by using vortex technique after that the master alloy and composite material casted in dies and prepared for sliding wear test , wear test was made under different conditions of applied load , sliding distance and surface roughness at the room temperature. The results show that wear rate increases with increasing any of the above conditions, also the composite material show higher resistance wear than of master alloy.
