Effect of Heat Treatment on Wear Rate of Al-4.5% wt. Copper Matrix Reinforced with Graphite and Zircon Sand Hybrid Composites

Abstract

In the earlier period the global necessitate for low cost, high performance and superior quality materials has made a shift in research from conventional materials to composite materials. In case of Metal Matrix Composites, aluminum matrix composites are broadly used in structural applications, aerospace and automobile industry due to their high strength to weight ratio, low cost and high wear resistance. In this investigation the effects of, individual and combined Zircons and, Graphite reinforcements and T6 heat treatment on the wear rate of Al-4.5%Cu alloy composites were examined. The matrix combination with Al-4.5%Cu as base was assorted in terms of weight percentages of zircon sand (2%, 4%, 6%, 8%) and constant 2% Graphite. of hybrid composite samples fabricated by using stir casting technique. The wear rate of these models was investigated prior to and after T6 heat treatment by means of pin on disc machine at room temperature under dry sliding conditions. These outcomes provide insight view of outcomes of reinforcements on particulate reinforced composites. These end results are compared with T6 Heat treatment and effect of the similar is evaluated.
