Experimental Investigation of Tribological Behaviour of Aluminium Alloy Based Metal Matrix Composites

Abstract

Metal Matrix Composites are a class of advanced composites with graded properties that bring a new concept in material design and are widely used in the aerospace and automotive industry. These materials have the properties of both the matrix as well as the reinforcement materials. They are known to have little residual and thermal stress. This concept imparts improved adhesive bonding strength between metals and ceramics. Aluminium alloy with silicon carbide is applicable where hardness and toughness are the requirements. Metal Matrix Composites are designed in order to have the combined properties of both metals and ceramics. The specimens are fabricated for various proportions of the materials. In the fabrication of these materials, begins with Aluminium alloy and Silicon carbide. The specimen is subjected to different mechanical tests, and the experimental result is the pure aluminium undergoes more wear when compared to the reinforced specimen.
