Abstract
In this study, the effect of aging on wear characteristics of the nano GNP reinforced Al6061 metal matrix was investigated. In this scope, the samples were produced by hot press at 500 oC temperature under 50 MPa pressure for 30 minutes. The wear characteristics of the composites were determined using the ball-on disc wear test method. The effect of aging on the friction coefficient and wear ratio was investigated. Graphene reinforcement significantly increased the friction coefficient between the stainless-steel ball and specimen but the aging process lowered the coefficient of friction to a better level. Also, artificially aged specimens showed significant increase in hardness values. Key factors affecting the mechanical performance of the Al based alloy is reinforcement and aging process.
