Abstract

Abstract: Aluminium matrix composites (AMC) strengthened with hard particles has given rise to a potential material particularly for wear resistant and weight basic applications. The effect of heat treatment of aluminium alloys sliding wear nature are observed under varying load and speed. Irrespective of materials heat treatment improves hardness of the material. The particulate reinforcements embedded with Al2218 Aluminium metallic element alloy with 4% constant weight proportion of Talc, Boron Nitride and a variable amount of hard reinforcement particulates. By introducing fly ash as reinforcement satisfies the structural and thermal properties. 5%, 10% & 15% of fly ash added to the composite by metal stir casting technique. The specimens are treated with ASTM T6 standard. Performance of heat-treated matrix composite was investigated with a pin on disc apparatus through a constant load 2 kg and with a desirable rpm. Hardness of the specimen at temperature were measured before and once the heat treatment. Heat treated metal exhibits high hardness and wear resistance. This investigation reveals that 2218 Aluminium matrix composites with high hardness and wear resistance will replace the material employed in Automobiles like brake drum, cylinder block, connecting rod, piston etc for higher performance and longer life.
