| Description |
Al alloy 2014- graphite particle composite was synthesized using a solidification processing technique. Wear tests of as-caste end of heat-treated alloys and composites were conducted under dry conditions on a pin-on-disc wear test apparatus. Scanning electron microscopy examination of sliding surfaces did not show the formation of a graphite film. It appeared from the present investigation that graphite particles either were engulfed in the coarse wear debris or might have been pulled off the sliding surfaces because of a poor inter-facial bond between aluminium and graphite. However, in (Al-Si alloy)-graphite composites in the heat-treated condition, the formation of a graphite film was detected. The present study suggests that the matrix micro-structure plays a significant role in the solid lubrication characteristics of graphite in aluminium alloys.
