Abstract

Purpose

The purpose of this study is to investigate the effect of nanographite content and the sliding time on the wear behavior of Cu-graphite nanocomposites.

Design/methodology/approach

Cu-graphite nanocomposites were produced by flake powder metallurgy from the copper and nanographite powders in the range of 0-5 wt.% of graphite. The effect of sliding time and content of B4C particles on the wear behavior of Cu-graphite nanocomposites was analyzed.

Findings

Results show that the wear mechanisms of copper and Cu-graphite nanocomposites are adhesive wear and delaminating wear, respectively. It was observed that the wear loss increased with increasing load. Wear loss of the Cu-graphite nanocomposites decreased with increase in graphite content. This was related to change in wear mechanism from adhesive to delamination wear.

Originality/value

Although there are a wide range of applications for Cu-based materials, there is a scarcity of literatures on the wear behavior of Cu-nanographite composites that can be used for electrical contact applications.
