- Abstract
In the present investigations, wear test is conducted on pin on disc device at room temperature for both the age hardening and without age hardening conditions. Al7075 has chosen as the matrix material. HMMCs are produced utilizing stir casting route for enhancing the wear behavior and hardness number. The reinforcement used is silicon carbide with 5%, 10% and 15% weight percentage and Al2O3 as the reinforcement in 5%, 10% and 15% weight percentage. In the aluminum matrix Microstructural characterization reveals the homogeneous mixing of reinforcements. This investigation shows the enhanced in wear resistance is due to the increment weight fraction of reinforcement. By raising the sliding speeds there is a reduction in the rate of wear and it reduces with increment in sliding distance. As an increase in weight fraction there is decrement in rate of wear of composites. In general tribological property enhances because of the addition of the two reinforcements.
