英文摘要	MoS2-based coatings present low friction coefficients in vacuum or inert environments, but they also present high wear rates in air environments, which is difficult to serve in complicate environments and extreme conditions. It is becoming more important to improve tribological properties in various environments for widely use. Conversely, carbon-based coatings exhibit good anti-wear properties in air environments, especially humid environments. In this study, we introduced the hydrogen-free carbon-chromium coating(Graphit-iC (TM)) into the MoS2 coating doped with titanium(MoST (TM)) by layer-by-layer deposition techniques, and we built a series of MoST/Graphit-iC multilayer coatings with different numbers of layers. The results show that multilayer coatings are composed of denser structure compared with the MoST coating. Furthermore, the tribological performance in various environments are significantly improved by building the multilayer structure. The lowest wear rate and longest wear life in ambient environment are obtained with 8 layers and the friction coefficient decreases to around 0.02 in vacuum environment. In addition, interfaces between MoST layers and Graphic-iC layers can inhibit the permeation of the corrosive mediums. Overall, the improvement of the tribological performance and corrosion resistance are attributed to the heterogeneous interfaces in multilayer coatings, and multilayer coatings exhibit great potential in widely use.
