Influence of Surface Ta Ion Implantation on Friction and Wear Behavior of Al Bronze
The distribution of Ta,Cu and Al in Al bronze with Ta ion implantation was analysed by auger electron spectroscopy(AES).The micro-hardness of Al bronze with Ta ion implantation was measurd by micro-hardness tester under different load conditions.The friction coefficient and wear mass loss were analyzed by friction tester.The results show that the concentration of Ta ion increases with the increase of Ta ion implantation dose,and the depth of Ta ion implantation is more than 100 nm.Morever,Ta ion implantation leads to increasing the micro-hardness of the Al bronze.The largest hardness value is achieved within a region about 60 nm deep from surface.Ta ion implantation reduces the friction coefficient and friction and wear volumes of the Al bronze.Therefore,Ta ion implantation can improve wear resistance of Al bronze.
