Effect of the graphite content on the tribological properties of hybrid Al/SiC/Gr composites processed by powder metallurgy

Abstract

Purpose

The purpose of this paper is to understand the effect of graphite content on the properties of aluminum alloy/silicon carbide/granite (Al/SiC/Gr) composites.

Design/methodology/approach

Hardness and wear tests were applied to the powder metallurgical composites, and microstructural characterization was conducted.

Findings

Optimum graphite content for maximum wear resistance is reported as weight 6 per cent.

Originality/value

Results of this study may help light weight Al/SiC/Gr composites to be used in different industrial applications.
