Studying the Dry Sliding Wear for Composite Material of Base (Al-4%Cu) Reinforcement by Silicon Carbide Particles

This work is concerned with a study of dry sliding wear of Aluminum bace alloy of (Al-4%Cu) reinforcement by silicon carbide particles with different percentage (3, 6,9,12 wt %SiC). Composite materials prepared by stir casting method using vortex technique. The base alloy and composite materials samples were tested to investigate wear behavior, using Pin -on-Disc technique, by examining some variables of wear such as applied load, sliding speed, and sliding time. The results showed that wear rate increases with applied load and sliding time, while increasing the sliding speed and the percentage of SiC decreases the wear rate, as well as the alloy containing (12wt% SiC) showed better wear resistance compared with other alloys .
