摘要
To improve fretting fatigue resistance (FFR) of Ti811 titanium alloy at elevated temperature, Al film was produced on the Ti alloy surface by ion assisted multi-arc deposition (IAD) method. The composition distribution, bonding strength, micro-hardness, wear resistance of the IAD Al film were compared with multi-arc ion plating (MIP) Al film. The influence of the IAD Al film on FFR of the Ti alloy was evaluated. The results indicated that IAD technique could prepare Al film with low hardness, excellent bonding strength and good lubricating property. The IAD Al film significantly improved the fretting fatigue resistance of the Ti alloy at 350°C.
