优化基于MoS 2的涂层以克服其湿度敏感性仍然是一个挑战。采用非平衡磁控溅射法制备了不同Pb含量的MoS 2/Pb复合涂层。涂层的微观结构由纯MoS 2的疏松柱状结构转变为Pb掺杂MoS 2的致密无特征结构。随着Pb含量的增加，MoS 2/Pb复合镀层的硬度和弹性模量逐渐增大，在Pb含量为8.9at%时出现最大值。进一步增加铅含量会导致涂层的硬度和弹性模量下降。系统评价了涂层在不同湿度条件下的摩擦学性能，并对其机理进行了探讨。结果表明，涂层的力学性能决定了涂层在干燥空气中的耐磨性，而涂层在潮湿环境中的抗氧化性能则决定了涂层的耐磨性。这有利于我们针对不同的操作条件定制或选择MoS 2基复合涂层。
Optimizing the MoS2-based coating to overcome its humidity sensitivity is still a challenge. In this work, MoS2/Pb composite coatings with various Pb contents were synthesized by unbalanced magnetron sputtering system. The microstructures of the coatings change from loose columnar structure for pure MoS2to a compact featureless structure for Pb doped MoS2. The hardness and elastic modulus of the MoS2/Pb composite coatings gradually increase with the Pb content increase and exhibit a maximum value at Pb content of 8.9 at%. Further increase in the Pb content results in a decrease in the hardness and elastic modulus of the coatings. The tribological performance of the coatings was systematically evaluated under different humidity conditions, and the underlying mechanisms were investigated. The results show that the mechanical property of the coating determines the wear properties under dry air; whereas the antioxidant property of the coating becomes prominent with regard to the wear-resistant in humid environmental. This benefits us to tailor or select the MoS2-based composite coatings for different operating conditions.
