Characterization of Fretting Fatigue Behavior of TiN/Ti Coating on Ti-811 Alloy at Increased Temperature
A TiN/Ti composite coating has been prepared on a Ti-811 titanium alloy substrate by an ion-assisted arc deposition (IAAD) technique.The composition distribution,microhardness,ductility,tribological properties,and fretting fatigue resistance (FFR) at increased temperature of the coating have been investigated.The results indicate that the IAAD technique can be used to prepare a TiN/Ti composite coating with high hardness,good ductility,excellent bonding strength,and high load-bearing capability.The TiN/Ti composite coating can improve the resistance to wear and fretting fatigue (FF) of the Ti alloy at 350 C because of the good toughness and high bonding strength of the IAAD TiN/Ti composite coating with excellent lubrication of Ti particles in the coating.
