Abstract: The sliding wear behaviour of forged hypereutectic ill-Si P/M alloys tested against hardened steel is investigated. Pin-on-disc tests are performed under sliding lubricating conditions in engine oil at temperatures up to 150 degrees C in order to simulate friction and wear behaviour in the contact between a connecting rod and the crankshaft in a car engine. The generalised Stribeck curve is measured to make sure that the pin-on-disc tests can be performed in the boundary lubrication regime. Investigation of the friction coefficient, the wear volume and the wear mechanisms indicates that ill-Si material shows a lower Value of both friction and wear rates, attributed to the formation of a tribe-chemically reacted surface layer, than AI-Sn material, though a stable wear condition is reached after a running-in period, reflected by a steady state friction coefficient, constant wear rate and stable wear mechanisms for both ill-Si and AI-Sn materials.
