Description

technical field [0001] The invention belongs to the technical field of self-lubricating coatings, in particular to a TiB 2 Self-lubricating coating, its preparation method and wear-resistant component. Background technique [0002] Solid lubricating coating means that the coating itself has good lubricating performance (low friction coefficient, low wear rate) in the absence of lubricating fluid or grease, so that it can be used under special working conditions. [0003] Solid lubricants are easily affected by the environment, and the lubricating effects produced under different temperature, pressure, and humidity conditions vary greatly. Therefore, the material, structure, and molding process of the lubricating coating must be reasonably designed to meet the needs of the project. [0004] At present, due to the limitation of friction and wear properties, the proportion of solid lubricants in industrial applications is still relatively small relative to liquid lubricants. ...
