This paper has studied the friction and wear behaviour of bearing materials Thordon XL,LgSn80 and AISI 1043 steel against plasma-sprayed A12O3 coatings under dry and lubricated sliding.The results show that Thordon XL has the best anti-wear performance in either dly case under lownormal load or lubricated case under high normal load among all the materials studied. However, LgSn80has better anti-wear performance in dry and lubricated case under high normal load. Thordon XL/Al2O3coating pair gives the lowest dry friction coefficient (0. 44) under normal load 45. 3 N at a velocity of 1m/s. The dry friction coefficients of LgSn80/A12O3 coating are in range of 0. 55-0. 60. This study hasanalyzed some relevant to wear mechanisms, the dominating wear mechanisms are shear flacture forThordon XL and abrasive wear for LgSn80.
