Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a high-temperature-resistant ceramic 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 splashing of the workpiece itself or high-temperature environmental factors, especially when industrial liquids such as cutting fluids are used, they often erode the processing tools and affect the processing tools. Machining accuracy and service life have an adverse effect on machining. 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 widespread attention. Unlike traditional coatings, the st...
