Wear behaviour of aluminium matrix composites are characterized by pin on disc wear test using various parameters such as sliding distance, sliding speed and load. MMC consists of aluminium alloy (A356) as the matrix material and particulate alumina of 5% and 10% by weight as the reinforcement was fabricated using stir casting. Wear resistance of composites are improved by the presence of reinforcements. Experiments were conducted based on the plan of experiments generated through Taguchi Technique. L9 orthogonal array was selected for analysis of data. The objective of this investigation is to study the influence of sliding speed, sliding distance, load and weight percentage reinforcement on wear rate of fabricated metal matrix composites.
