Abstract

This article describes the dry sliding wear of 6061 aluminium alloy and composites containing up to 14 vol.% of graphite particle dispersions prepared by a power metallurgy route. Experiments were carried out with pin specimens against an EN25 steel disc using a pin-on-disc apparatus. The effects of varying sliding speed and distance, applied pressure and material characteristics, as well as the amount of graphite, on the dry sliding behaviour have been evaluated. The wear rates of the composites increased with increasing amounts of graphite. This anomalous behaviour has been attributed to the increased porosity (interconnected and interfacial) in the composites. SEM examination of the worn surfaces did not reveal the presence of graphite film on them. Most of the wear debris were flaky in nature.
