Abstract
Description
technical field
[0001] The invention relates to a preparation method of a high-strength nickel-based high-temperature self-lubricating composite material. The material is characterized by high strength and excellent lubricity at the same time, and can be used at a low temperature to 900°C. Background technique
[0002] Modern industries such as aerospace, metallurgy, machinery, automobiles and nuclear power have huge demands for materials and technologies with continuous lubrication in a wide temperature range from room temperature to high temperature. There are more and more lubrication problems involving high-temperature moving parts at temperatures of 700°C or higher. When the mechanical moving parts are at a temperature higher than 400°C, their lubrication and wear resistance issues become the key to the safe, reliable and stable operation of the entire system. At present, there are two methods to solve the problem of high temperature lubrication mainly through self-lub...
