Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a nano-ceramic high-temperature-resistant coating material with excellent high-temperature resistance and wear resistance and a preparation method thereof. Background technique [0002] In the field of mechanical processing, when processing tools such as machine tools, they are affected by the debris of the workpiece itself or environmental factors, which often cause corrosion to the processing tools, affect the processing accuracy and service life of the processing tools, and have an adverse effect on mechanical processing. , Therefore, surface coating treatment for processing tools can effectively overcome this problem. [0003] In recent years, coating materials have developed rapidly, especially ceramic coating materials, which have received extensive attention. Traditional ceramic materials are relatively brittle, and the lack of further processing...
