In this study, focusing on the improvement in the tribological properties of the coating, the effects of film characteristics were investigated. The film life was evaluated by a sliding test against an aluminum alloy. The wear rates were evaluated by a ball-on-block test and a micro slurry-jet erosion test. From the sliding test, it was revealed that the (111) preferred oriented TiN film shows a wear mode of only micro chipping without large-scale scratching. The film life of this film is about 1.5 times as long as an ordinary TiN film. From the MSB test, it was also revealed that the (111) preferred oriented TiN film shows higher erosion resistance than the ordinary TiN film. However the (111) preferred oriented TiN film does not show higher wear resistance at the ball-on-block test.
