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.

Claim (Index 11):
The method of  claim 1 , wherein the method further includes forming a titanium layer on the metal base prior to forming the metal nitride layer,\n wherein in forming the metal nitride layer, the titanium layer is nitrided to form an adhesion improving layer made of titanium nitride (TiN).
