    摘要： The present invention relates to a machining tool having a substrate surface made of a hard metal or a ceramic material, said substrate surface containing hard material particles on the basis of carbide and/or nitride and/or oxide that are embedded in a cobalt-containing binder matrix, and the substrate surface being smoothened. The substrate surface of the machining tool can be smoothened by way of a treatment with an ion beam that consists of monomer ions of at least one cation species, the cation species being mono-or poly-charged and being selected from the group consisting of: cations of the main group elements lithium, boron, aluminum, gallium, carbon, silicon, germanium, nitrogen, phosphorus and oxygen; and cations of the transition metals titanium, zirconium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, iron, cobalt, nickel and copper.

    摘要： A hard coating layer on a cutting tool includes at least a Ti and Al complex nitride or carbonitride layer and has an average layer thickness of 1 to 20 μm. In a case where a composition of the complex nitride or carbonitride layer is expressed by: (Ti1-xAlx)(CyN1-y), a content ratio x and a content ratio y satisfy 0.60≦x≦0.95 and 0≦y≦0.005, where x and y are in atomic ratio. Crystal grains constituting the complex nitride or carbonitride layer include cubic phase crystal grains and hexagonal phase crystal grains. An area ratio occupied by the cubic phase crystal grains is 30-80%. An average grain width W is 0.05-1.0 μm. An average aspect ratio A of the crystal grains with the cubic grain structure is 5 or less. A periodic content ratio change of Ti and Al in (Ti1-xAlx)(CyN1-y) exists in each of the cubic phase crystal grains.

    摘要： A hard coating includes two first crystalline phases, and a second crystalline phase containing AlN of a wurtzite-type crystal structure disposed therebetween. The two first crystalline phases each include, independently, a laminate structure having a Ti1-x1Alx1N phase having a sodium chloride-type crystal structure, and an Alx2Ti1-x2N phase having a sodium chloride-type crystal structure that are alternately stacked. An Al composition ratio x1 satisfies a relationship 0.5≦x1≦0.75, and an Al composition ratio x2 satisfies a relationship 0.75
