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 14):
The coating film of  claim 12 , wherein the carburized layer includes:\n a high carbon content portion; and a low carbon content portion disposed between the metal nitride layer and the high carbon content portion, wherein the low carbon content portion has a smaller carbon content per unit area than a carbon content per unit area of the high carbon content portion.
