Abstract

In the present work, A356/SiC Metal Matrix Composite (MMC) with different weight percent of SiC particles were fabricated by two different techniques, such as Mechanical stir-casting and Electromagnetic stir casting. The wear and frictional properties of the metal matrix composites were studied by performing dry sliding wear test using a pin-on-disc wear tester for both electromagnetic stir casting samples and mechanical stir casting samples. The wear rate increases with the addition of normal force, while decreases when the percentage of reinforcement is increased. Frictional coefficient increases by increasing the normal force and percentage of reinforcement. By increasing percentage of reinforcement and using electromagnetic stir casting process, the higher frictional coefficient and lower wear rate are obtained.
