摘要：
Al based self-lubricating hybrid composites containing SiC as the hard phase and MoS2 as the solid lubricant were synthesized by using stir casting route. Dry sliding wear and friction characteristics of the composites have been examined at sliding speed of 1 m/s on a pin-on-disc tribometer under different normal loads of 9.8N, 14.7N, 19.6N, 24.5N. Both friction and wear rates were found to reduce with addition of MoS2, however, bonding between the matrix and reinforcements was not good. Hence, Mg was added to improve the wettability and this resulted in improved mechanical as well as tribological performance.
