Abstract

Abstract: In this present experimental work, magnesium matrix composites (MMCs) were manufactured by stir casting method. Magnesium is a metal which is more abundant and has very less density but the problems is it has better wear resistance and low hardness. To improve the properties of magnesium, ZrSiO4 ceramic powder are reinforced. The tribological and mechanical properties of composite materials were investigated. The effects of reinforcement on the mechanical properties of the composites were investigated by 0, 4 and 8 wt% of ZrSiO4 ceramic powder with a size of 40–60 µm. The primary aim is to investigate the mechanical and tribological behaviour of AZ91/ZrSiO4 composites. ZrSiO4 powders are added at required proportions to produce magnesium alloy (AZ91) matrix composites. AZ91 along with ZrSiO4 confirms fine mechanical properties. The demand of magnesium matrix composites has increased mainly due to its high specific strength, better damping properties, excellent cast ability and superior machining ability.
