本文扼要介绍了难熔金属钼基复合材料摩擦表面上,用硫化来制备二硫化钼薄膜的原理,探测了硫化工艺参数对润滑薄膜质量的影响,用金相法和X射线谱线分析了润滑薄膜的组织和结构,并在真空条件下进行了对摩试验,测定其摩擦系数,最后,将此润滑薄膜用于滚动轴承中,在高温、高真空等特殊工况下进行了寿命试验。 In this paper, the principle of molybdenum disulfide film prepared by vulcanization on the rubbing surface of refractory metal molybdenum matrix composites is briefly introduced. The influence of vulcanization process parameters on the quality of lubricating film is investigated. The influence of vulcanization process on the quality of lubricating film is analyzed. Structure and structure of the roller bearing were tested. The friction test was carried out under vacuum and the friction coefficient was measured. Finally, the lubricating film was used in the rolling bearing. The life test was carried out under special conditions such as high temperature and high vacuum.
