由于我国社会主义建设事业的飞速发展,各种机器性能的迅速提高,普遍采取了《极限设计》方案,因此对于轴承使用条件的要求日益严格,轴承的使用温度不断提高,各工业部门均提出了不少的高温润滑问题。解决高温润滑问题已经是近代科学技术中的重要研究课题之一~([1、2])。从我们以前的工作看到~([3]),氧化铅基膜在室温至700℃的温度范围内对降低摩擦、磨损方面是有效的。特别是将氧化铅基料与固体润滑剂配成一定比例,
Due to the rapid development of China’s socialist construction and the rapid increase of various machine functions, the “extreme design” scheme has been adopted universally. Therefore, the requirements for bearing service conditions have become increasingly stringent and the service temperature of bearings has been continuously raised. Various industrial sectors have proposed A lot of high temperature lubrication problems. To solve the problem of high temperature lubrication has been one of the important research topics in modern science and technology ([1,2]). As seen from our previous work ~ ([3]), the lead oxide base film is effective in reducing friction and wear at room temperature to 700 ° C. In particular, the lead oxide and solid lubricant into a certain proportion,
