摘要： A surface-coated cutting tool according to the present invention includes a base material and a coating film formed on the base material. The coating film includes one or more hard layer and one or more oxygen-rich hard layer. The hard layer is crystalline in its entirety or crystalline with a part thereof being amorphous. The oxygen-rich hard layer and the hard layer are stacked and the oxygen-rich hard layer is amorphous in a region of interface with the hard layer.

摘要： Hard composite material for tools, comprising a substrate of CBN sintered body containing more than 20 % by volume of cubic boron nitride or diamond sintered body containing more than 40 % by volume of diamond. The substrate has at least one layer of hard heat-resisting film consisting mainly of Ti, Al and at least one element selected from a group comprising C, N and O on a portion or portions of said substrate where cutting participate. Improved in strength of base material, wear-resistance and oxidation-resistance, less reactive with iron and showing longer tool life comparing to known cutting tools and usable in wider applications such as hardened steel, cast ion and simultaneous cutting of cast ion and aluminum alloy.

摘要： A surface-coated cutting tool which comprises a substrate, an inner coating layer formed on the substrate with a compound comprising Al, at least one element of Cr and V, and one or more elements selected from nitrogen, carbon and oxygen, and an outermost coating layer formed on the inner layer with a carbonitride of TiSi. The surface-coated cutting tool is suitably used for a drill, an end mill, an edge replacement type of tip for milling and turning, a metal saw, a gear cutting tool, a reamer, a tap, and the like, and exhibits the improved resistance to exfoliation and wear, as compared to a conventional tool.
