Friction and Wear Behaviour of Cenosphere Dispersed Aluminium Matrix Composite Fabricated by Powder Metallurgy Route

Abstract

In the Present work cenosphere dispersed aluminium matrix composites were fabricated by powder metallurgy route. The friction and wear behaviour of these composites were studied by using a pin on disc machine. Various weight percentages of cenospheres (10, 20, & 30 wt. %) were reinforced with pure aluminium. The results showed that density decreases with addition of cenospheres but hardness increases with addition of cenosphere particles. The dry sliding wear mechanism was also established and presented in detail. The sliding wear test shows a significant improvement in wear resistance of pure aluminium with addition of cenosphere particles. SEM studies were also carried out to know the wear surface morphology of the products.
