Characteristics of TiVN and TiVCN Coatings by Cathodic Arc Deposition

摘要

Currently, TiVN and TiVCN coating are not prevailing in the literature. Only a few publications are revealed with basic properties. In this study, the TiVN and TiVCN coatings are deposited by using cathodic arc deposition system with Ti and TiV alloy dual targets. The result shows that V and C addition lead to the increase of surface roughness by droplets deposition in the TiVN and TiVCN coatings as compared to TiN. However, grain size of the TiVN and TiVCN coatings is obviously reduced by adding the V and C in the coating. The highest hardness and the best wear resistance are obtained for the TiVCN coating. Thermal stability of the TiVCN coatings is affected by the C addition resulting in severe oxidation.
