An experimental programme was established to determine the wear behaviour of TiN coatings of thickness 1 $\mu$m and 3 $\mu$m. by PECVD with the variation of applied load, sliding velocity and sliding distance. It was shown that oxidation of transferred metal as sliding speed increased formed oxide film so that it contributed in decreasing the wear rate. With the roller-on-disc tribometer employed, the wear rate of the roller specimen was decreased with the increase in sliding distance due to the reduction in effective contact pressure. Finally, the severe cracks concentrated at the trailing edge of contact surface were explained in terms of high tensile stress prevailing at the trailing edge of the contact and were identified as a dominant wear mechanism as well as the strong local welding between coating layer and the counter surface, leading to the debonding of the coating layer.

현재 엘리베이터용 worm gear의 wheel로써 가장 많이 사용되고 있는 것은 인청동이다. 일반적으로 청동에 인의 함량이 0.05% - 0.5% 정도 잔류하는 인청동은 용탕의 유동성이 좋아지고, 합금의 강도, 경도가 증가하며 내마모성, 탄성이 증가한다. 또한 P는 극소량 Cu 중에 고용하나 그 외에는 경하고 취약한 $Cu_3P$상으로 존재하고, P의 함유에 따라 Sn의 고용도가 저하하므로 주조 조직중에 $\delta$상($Cu_{31}Sn_8$)이 증가하여 Sn을 증가한 때와 같이 경도가 커지는 효과가 있다. 이같이 기지상 중에 간단한 3원 공정부 ($\alpha + \delta + Cu_3P$)상이 산재하여 있어 이것이 마찰상대면을 지탱하여 내마모 역할을 하기 때문에 인청동이 내마모 재료로써 많이 쓰이고 있는 것이다.
