Wear characteristics of 0.13 wt. % plain carbon steel, heat treated under various conditions, were monitored on a standard pin-on-disk wear testing machine under the normal loads of 2.5, 4.5 and 5.5 kg and at a constant sliding velocity of 1 m/s. Weight loss of the specimen was measured at various time intervals to obtain wear rate. The variation in volume loss with sliding distance indicated the presence of run-in wear followed by steady state wear. The wear mechanism was found to be primarily oxidative in nature, which was confirmed by the analysis of worn surfaces and wear debris generated during sliding. Wear resistance was found to be dependent on the microstructure and morphology of the phases. The wear coefficients calculated for various heat-treated specimens revealed that the ferrite-coarse pearlite, ferrite-fine pearlite, ferrite-tempered martensite and ferrite martensite structures show the wear resistance in decreasing order.
