  • Patent number: 11834737
    Abstract: The titanium alloy coating film of the present invention is represented by (Ti1-aMoa)1-xNx, which satisfies 0.0423 a?0.32 and 0.40?x?0.60 and in which the film hardness thereof satisfies at least a condition of 3,000 HV or more; and the titanium alloy target material is represented by Ti1-aMoa, which satisfies 0.04?a?0.32, and in which, when an X-ray diffraction profile is measured on a surface of the target material, a diffraction peak intensity attributed to a single metal phase of Mo is not detected.
