Summary Pin-on-discexperiments were carried out to produce both oxidative and metallic wear. Measurementof the temperature rise of the aluminium wear pins and calculations basedon these results show that the temperatures are too low to account for the oxide produced during wear. Oxidation during wear occurs by a two-stage processof oxidation of asperitiesfollowed by fracture and compaction into the valleys on tlle metal surface.As the oxide layer increasesin thickness it also becomessmoother and the wear rate remains relatively low.
