Abstract

Hybrid metal matrix composites are the composites consisting of two reinforcement constituents in a metal or in an alloy to enhance the properties of the base metal or alloy. In the present study rice husk ash and aluminum oxide are the two reinforcements. The base metal or matrix metal is aluminum alloy (Al-Si12). The reinforcements are added in equal quantity. Different composition combination (2, 4, 6, and 8wt. % of aluminum alloy) has been taken of the reinforcements. In this research the effects of the reinforcements on the mechanical (micro hardness, tensile and flexural strength) and tribological properties has been studied. Wear test is performed on the pin-on-disc apparatus. The wear performance of the hybrid metal matrix composites (MMCs) is evaluated at load of 1kgf. Sliding distance is 1000meter and the sliding distance is 1.5m/s. The result shows that increase in the percentage of the reinforcement leads to increase in mechanical properties (tensile strength, flexural strength and micro hardness) and tribological properties.
