随着航空、航天、核能等尖端技术的发展,对材料的耐高温性能及其在高温条件下的润滑提出了更高要求,如绝热柴油发动机轴承衬垫的工作温度达600—1000℃;汽车燃汽涡轮发动机,其工作温度为260—1100℃;其主轴温度达650℃;航空燃汽涡轮发动机的工作温度为250—1000℃;超音速飞机中控制装置的轴承表面温度达800℃;航天飞机控制装置的表面摩擦密封湿度达850℃,等等.八十年代以来摩擦学界已将此列为摩擦学应解决的重点课题之一.普通润滑油,润滑脂及其他有机润滑剂已不可能在这样高的温度下使用,而无机固体润滑剂,如一些氧化物、氟化物、软金属等,以其优异的耐高温性能引起人们的重视.近年来,为解决高温工程材料在高温条件下的润滑问题,采用无机固体润滑剂已被证明是一条有效途径.
With the development of cutting-edge technologies such as aviation, aerospace and nuclear energy, higher requirements are put forward on the high temperature performance of materials and their lubrication under high temperature conditions. For example, the operating temperature of bearing pads for adiabatic diesel engines reaches 600-1000 ° C; Gas turbine engine operating temperature of 260-1100 ℃; its spindle temperature of 650 ℃; aviation gas turbine engine operating temperature of 250-1000 ℃; supersonic aircraft control device bearing surface temperature of 800 ℃; aerospace Aircraft control device surface friction seal humidity of 850 ℃, etc. Since the eighties tribology has been listed as one of the key topics of tribology should be tackled. Ordinary lubricants, grease and other organic lubricants has been impossible In such a high temperature use, and inorganic solid lubricants, such as some oxides, fluorides, soft metals, with its excellent high temperature performance caused by people’s attention.In recent years, in order to solve the high temperature engineering materials at high temperature conditions The problem of lubrication, the use of inorganic solid lubricants has proved to be an effective way.
