Assessment of Wear rate and Coefficient of Friction of Al6262 WC/MoS2 under wet sliding condition

Abstract

The present paper aims at the results of an experimental examination of hybrid metal matrix composites using stir-casting technique.Aluminum alloy (Al 6062) samples reinforced with Tungsten Carbide (WC) and Molydedneum diSulphide are given. 2wt.% , 4wt.%,6wt.% of MoS2 and 3 wt.%, 6 wt.%, 9 wt.% tungsten carbide were mixed together with the aluminum alloy to create the hybrid composite. The tribological aspects of aluminium composites were studied using Pin on disc Method under wet sliding condition.Testing the hybrid composites' hardness revealed that raising the weight percentage of tungsten carbide might raise the hybrid composites' hardness. To examine the wear behavior of hybrid composites, the Taguchi method was utilized in the design of experiments (DOE) approach. The factors that were found to affect wear rate included load, sliding speed, and reinforcing percentage of WC and MoS2 are the most influencing parameters.
