Abstract :
The AlSn20 coatings on bearing alloy were deposited using magnetron sputtering technology. The influence of tin target current on the microstructure, hardness, corrosion resistance, bonding force and friction coefficient were analyzed. The results show that when the tin target current are in the scope of 0.19A ∼0.25A, with the decreasing of it, the coating changes from rough structure to fine structure. The hardness of the coating is inversely proportional to the tin target current. When tin target current is 0.19A, its hardness is the hardest, i.e 79HV0.025, the bonding force between coating and matrix is 36N and the friction coefficient achieves 0.15.
