    摘要： Coating-film furnished coated tools that are lubricative while maintaining resistance to wear are realized by coated tools in which a plurality of coating films is furnished on a base part. Furnished as the coating are one or more layers of, respectively: a first film composed of one compound selected from nitrides, carbides, carbonitrides, oxynitrides and carboxynitrides of TiSi; and a second film composed of one compound selected from nitrides, carbides, carbonitrides, oxynitrides and carboxynitrides of one metal M selected from Ti, Cr, and TiCr. The first film and the second film are laminated in alternation.

    摘要： The principal object of the present invention is to provide a coated cemented carbide tool whose both properties of breakage resistance and wear resistance are improved and whose life is lengthened. The present invention has been made to achieve this object and is related with a coated cemented carbide cutting tool comprising a substrate consisting of a matrix of WC and a binder phase of an iron group metal and a plurality of coated layers provided on a surface of the substrate, in which (a) an innermost layer, adjacent to the substrate, of the coated layers consists essentially of titanium nitride having a thickness of 0.1 to 3 &mgr;m, (b) on a mirror-polished cross-sectional microstructure of the said tool, an average crack interval in the coated film on a ridge of a cutting edge and/or rake face is smaller than an average crack interval in the coated layer on a flank face, (c) at least 50% of the cracks in the coated film on the said ridge of the cutting edge and/or rake face have ends of the cracks in the said innermost titanium nitride layer, in a layer above the titanium nitride layer or in an interface between these layers and (d) an average crack length in the coated film on the said ridge of the cutting edge and/or rake face is shorter than an average film thickness on the flank face. According to the present invention, quantitatively specifying the crack intervals and positions of the ends of the cracks in the coated layer results in excellent breakage resistance as well as wear resistance.
