中文摘要：

采用多弧离子镀结合低温离子渗硫技术制备了织构化MoS2薄膜,借助扫描电镜及X射线能量色散谱仪对其形貌及组成进行了表征,利用往复摩擦磨损试验机研究了其与激光表面织构的摩擦学协同效应,并基于磨损表面的形貌及组成分析,探讨了其润滑抗磨机理。结果表明：MoS2薄膜主要由球形或近球形颗粒组成,结构较为均匀致密,与激光织构具有良好的协同减摩抗磨作用。相对单一的MoS2薄膜而言,织构化MoS2薄膜能使摩擦系数及上下试样磨损率分别进一步降低约27.5%、21.2%和52.6%。表面织构因其＂微观动压＂及＂机械捕捉＂效应,能够促进MoS2颗粒的二次释放和重新转移并铺展形成低剪切强度的保护层,进一步降低摩擦磨损。

英文摘要：

The textured MoS2 film was prepared by multi-arc ion plating process together with low-temperature ion sulphurizing technique. The morphology and composition of as-prepared MoS2 film were characterized with SEM and X-ray energy dispersive spectroscopy. The synergistic tribological properties between the as-prepared film and the laser surface texture were investigated by the reciprocating friction and wear tester. The lubricating and anti-wear mechanisms were discussed based on the morphology and elemental analysis of worn surfaces. Results show that the MoS2 film has a uniform and compact structure with spheric and nearly spheric particles and appears excellent synergistic friction reduction and anti-wear properties with the laser surface texture. The corresponding friction coefficient and wear rate for upper and lower specimens decrease by 27.5%, 21.2% and 52.6%, respectively, referenced to those of the MoS2 film alone. The texture can promote the secondary release and transfer of MoS2 particles onto the contact surface to form a protective film with low sheafing strength due to the microdynamic pressure and mechanical entrapment effects, which is responsible for the further reduced friction and wear.
