摘要
PURPOSE: A covered hard alloy for cutting tools and wear resistance tools having cutting performance with superior wear resistance, impact resistance and heat resistance is provided. CONSTITUTION: In a TiAlN based multi-layered hard thin film coated on cutting tools or wear resistance tools using physical deposition method, the multi-layered hard thin film is formed by alternately laying up TiAlN covered hard layer and TiAlCrN covered hard layer on the tools in the order of TiAlN/TiAlCrN/TiAlN/TiAlCrN...., wherein the TiAlCrN covered hard layer comprises a composition of (TiaAlbCrc)N, wherein a+b+c=1, c= 5 to 12 at.%, the TiAlN covered hard layer comprises a composition of (TiaAlb)N, wherein a+b=1, a=50 to 60 at.%, and b=50 to 40 at.%, the multi-layered hard thin film is formed on the tools as a 100 to 1700 layer by alternately coating the thin film layer in the structure of TiAlN/TiAlCrN, and the TiaAlbCrcN covered hard layer has a preferential growing direction of 200 surface.
