A method of treating the surface of a blade
By treating the cutting tool in a low-temperature nitrogen atmosphere through a multi-stage immersion method, a dense honeycomb wear-resistant layer with dense hole walls is formed. This solves the problems of insufficient coating consistency and adhesion in physical vapor deposition coating methods, achieving high adhesion and wear resistance, and is suitable for high-end precision cutting tools.

Abstract
The application provides a blade surface treatment method, and 1,3-bis(chloromethyl)tetramethyldisilazane is used in A liquid for forming a base film, which can form a stable covalent bond with the blade on one hand, and the active chloromethyl end thereof can provide abundant reaction sites for the honeycomb film layer, promote the chemical bonding of the film layer, and polyvinylpyrrolidone and cetyltrimethylammonium bromide which can be carbonized are used as a template agent, which can not only provide a dense multi-stage pore structure, but also form a carbon-silicon composite structure, and finally, a mixture of perhydropolysilazane and cage-type silsesquioxane is used before film forming, which can fully overcome the brittleness of pure SiO2; the prepared coating has high stability and strong adhesion, and can meet the requirements of high-end fields or precision high-speed numerical control equipment tool bits.
