Description

Technical field [0001] The invention relates to a TC4-based self-lubricating material with Sn-Ag-Cu and TiC as lubricating phase and reinforcing phase, and a preparation method thereof. Background technique [0002] With the rapid development of modern industrial technology, especially aviation and aerospace technology, some moving parts under extreme working conditions such as high temperature, high load, strong radiation and other environments have put forward a higher level of high temperature resistance and wear resistance of lubricating materials. The higher the requirements come. Therefore, there is an urgent need to develop solid lubrication technology to solve the lubrication failure problem of traditional lubricating materials under severe working conditions. Solid self-lubricating materials have received wide attention from scholars at home and abroad because of their good anti-wear and wear-resisting effects under harsh environments such as high temperatures and high ...
