Effect of Fly Ash Content and Applied Load on Wear Behaviour of AA6063 Aluminium Alloy

Abstract

The AA6063 alloy reinforced with 0, 2, 4 and 6 wt. % of fly ash (FA) particulate composites were produced by the compocasting technique. In this study, the effect of FA content and sliding speed on the wear behaviour of AA6063-FA composite was investigated. The wear was carried out by using pin on disc apparatus against rough steel counterface. These wear tests were conducted at applied load of 24.5, 49 and 73.5 N respectively with the constant sliding speed (150 rpm) and sliding time (10 minutes). In the results, it has been observed that upon addition of FA particles, the wear resistance of AA6063 -FA composites was enhanced. The wear rate reduced with the increase in the content of FA particles. While the wear rate increased with increase in the applied load.
