Wear and friction behaviour of aluminium metal composite reinforced with graphite particles

Abstract

Present paper discusses the effect of graphite powder on the wear and friction properties of aluminium melt. The aluminium graphite composite was fabricated using the stir casting technique. Three different amounts of graphite particle with 2 wt. %, 4 wt. % and 6 wt. % are used for the fabrication of the composite. Pin on disc experiments were performed as per ASTM-G99 between aluminium graphite (Al-Gr) composite and mild steel tribopair. Scanning electron microscope images for the worn Al-Gr composite were obtained to study the wear of the composite. It is observed that graphite particles help in reducing the wear and friction coefficient of the aluminium.
