摘要：

The TiCN coatings were deposited on Ti6Al4V alloy by an arc ion plating technique. In order to improve the adhesion of TiCN coating, a buffer layer of Ti and TiN was prepared between titanium substrate and TiCN coating. The effect of buffer layer on dynamic wear resistance of TiCN coating on titanium alloy in artificial seawater was studied. Results show that all the TiCN films have dense structure with a total thickness of about 2 mu m. The TiN/TiCN coatings have a higher hardness of 30 GPa. The TiN buffer layer has a higher adhesion for the TiCN coating; Lc(1) and Lc(2) are 60 N and 80 N, respectively. The TiN/TiCN coatings have a excellent wear resistance with a lower friction coefficient and wear rate.
