  • Method for forming coating film having high heat resistance, high hardness and abrasion resistance, coating film having high heat resistance, high hardness and abrasion resistance, and cutting tool comprising same
    Patent number: 10597781
    Abstract: The present disclosure relates to a method for producing a coating film having high heat resistance, high hardness and wear resistance, a coating film having high heat-resistance, high hardness and wear resistance produced using the method, and a cutting tool including the same. The method includes forming a metal nitride layer on a metal base; forming a carbon layer on the metal nitride layer; and irradiating a laser into the carbon layer to add carbons into a portion of the metal nitride layer, thereby to form a carburized layer.
