MoS 2-based composite coatings were deposited with the nano-compound unbalanced plasma plating technique. The effects of processing parameters and working environments on the tribological properties of the coatings were examined by the drilling experiments and XPS. The distances between substrate and Ti target, Ti content and deposition pressure were varied in order to determine the optimum conditions for producing lubricious, long-lasting MoS 2-based coatings. It is found that the tribological performance of TiN-MoS 2 coating decreases rapidly in humid air but the humid-resistant property of TiN-MoS 2/Ti coating improves evidently.It is indicated that the humid-resistantance property and the abrasion durability of MoS 2-based coatings can be enhanced markedly by adding Ti with a certain contents.
