采用磁控溅射技术，研究了气氛对AISI304钢表面MoS2涂层摩擦学性能的影响。对其耐磨性和失效机理进行了评价。结果表明：随着真空度的增大，摩擦系数和磨损系数均增大；背景真空环境中氧气和H2O的引入显著促进了转移膜的形成，导致MoS2中晶体取向的紊乱和缺陷的引入，这将加强52100钢轴承球与转移膜之间的粘接相互作用，从而导致MoS2涂层的磨损寿命延长。
This paper explores the effects of atmosphere on the tribological behavior of MoS2 coatings deposited on the AISI304 steel using magnetron sputtering. The wear resistance and corresponding failure mechanisms were evaluated. The results show that both the friction coefficient and wear coefficient increase as the vacuum degree increases. The introduction of oxygen and H2O into the background vacuum environment significantly promotes the formation of transfer films, and results in the disorder of the crystal orientation and defect introduction in MoS2, which will strengthen the adhesive interactions between 52100 steel bearing ball and transfer films, and then leads to the prolongation of the wear life of the MoS2 coatings.
