摘　　要：采用扫描电镜观察、摩擦磨损试验和盐雾试验等研究了Monel合金粒子注入对MoS2固体润滑膜形貌及摩擦性能、耐盐雾腐蚀性能的影响。结果表明:Monel合金粒子的注入使MoS2膜层更加致密完整,有效提高了MoS2固体润滑膜的润滑性能和耐腐蚀性能,其平均摩擦因数约为0.103,摩擦寿命超过60mim;盐雾试验后膜层的润滑性能变化不大,膜层的保护等级和外观等级均为10级,满足航天飞行器特种固体润滑材料在海洋环境下的润滑和耐盐雾腐蚀的双重要求。The effects of Monel alloy particle implantation on structure and properties of MoS2 solid lubricant coating were studied by scanning electron microscopy observation, friction-wear testing and salt spray testing. The results show that the MoSe solid lubricant coating became more compact and complete because of the implantation of Monel alloy particles, which improved effectively both lubrification and corrosion resistance of the coating. And the average friction coeffecient of the coating implanted Monel alloy particles around 0. 103, while wear life was over 60 min. The lubrifieation of the coating changed little after salt spray testing, while its protection property and appearance reached grade 10, which satisfied the needs for solid lubricant materials for spacecraft on lubrification and salt spray corrosion resistance under marine environment.
