The influence of TiAlN films on the fatigue mechanism and friction property of Ti-6A1-4V alloy coated with TiAlN film by the physical vapor deposition (PVD) was studied in vacuum at 773K from the view point of mesoscopic size which is 1 μm-1mm size range on the fatigue test and in dry and air condition at room temperature on friction test. The results indicated that the fatigue strength of coated Ti-6Al-4V alloy as well as uncoated Ti6Al-4V alloy at an elevated temperature and friction coefficient of coated Ti-6Al-4V alloy was lower than uncoated Ti-6A1-4V alloy. TiAlN films reduced plastic deformation and crack initiation in surface. Therefore the fatigue process of coated Ti-6Al-4V alloy was dominated by initiation and growth mechanism of some cracks.
