Abstract
Al-graphite and Al-Nanographite particulate metal matrix composites were prepared by two step stir casting method. The reinforced particulates in the metal matrix composites varied from 5% to 10% by volume fraction. Tribological performances of these composites were evaluated based on graphite particle size and normal load using a pin-on-disc tribometer. Al-Nanographite composites show higher load withstanding capacity and low coefficient of friction compared to aluminium graphite composites by the way of forming a thick graphite layer at the contact surface.
