摘　要:研究分析了聚四氟乙烯润滑油脂的减摩性能,得出了聚四氟乙烯润滑油脂摩擦因数与转速、温度和载荷变化关系。利用SEM和EDS对3种润滑剂摩擦膜进行形貌和能谱分析,认为聚四氟乙烯润滑油脂减摩是表面物理吸附膜和化学迁移膜共同作用的结果。[著者文摘]

Research on Tribological Properties and Friction Mechanism about Fluorinated Lubricant GreaseYang Guanglei, Li Qingzhong Ni Zifeng1.School of Mechanical Engineering,Jiangnan University,Wuxi Jiangsu 214122,China;2.Wuxi Technician College,Wuxi Jiangsu 214153,ChinaAbstract:The friction properties of fluorinated lubricant grease were investigated,the friction properties which change with rotate speed,load and temperature were discussed.The wear scar morphologies of the surfaces lubricated by three kinds lubrication oils were analyzed by using scanning electron microscopy（SEM）,and the element concentration were analyzed by X-ray energy spectrum（EDS）.The theoretical analysis shows that because the combined effects of physical adsorption film and chemical migration film formed on friction surface,the fluorinated lubricant grease has good friction reducing properties.[著者文摘]
