Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and particularly relates to a nano-ceramic coating material for machine tools with excellent high temperature resistance and wear resistance and a preparation method thereof. Background technique [0002] In the field of machining, machining tools such as machine tools are affected by the debris of the workpiece itself or environmental factors when processing the workpiece, which often corrosives the machining tool, affects the machining accuracy and service life of the machining tool, and adversely affects the 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. Different from traditional coatings, the strength and wear resistance of coatings are not satisfactory in the field of mechanical ...
