Studies on Dry Sliding Wear Characteristics of Ceramic Al₂O₃ Particulate Reinforced 6061Al Matrix Composites

Abstract:

In the current investigation an attempt has been made and to produce ceramic Al₂O₃ particulate reinforced 6061Al matrix composites by liquid metallurgy route (stir casting technique) and to study the dry sliding wear properties of the prepared composites. The amount of ceramic Al₂O₃ particulate reinforcement addition was maintained at 9 and 12wt%. During the preparation of each composite the ceramic reinforcements were introduced in a novel way which involves three stage additions of reinforcements during melt stirring. The wear tests were conducted using pin on disc wear testing machine on 6061Al matrix before and after addition of Al₂O₃ reinforcements Wear test results demonstrated the superior wear resistance of the composites over monolithic 6061Al alloy matrix. Key Words: MMC’s, Al₂O₃ particulates, 6061Al, stir-casting
