Abstract:
The hard-coated member of the present invention having a compression-stress-loaded hard coating having a thickness of 5 μm or more, the hard coating having a face-centered cubic structure having a composition represented by (Me1-aXa)α(N1-x-yCxOy), wherein Me is at least one element selected from Groups 4a, 5a and 6a, X is at least one element selected from the group consisting of Al, Si, B and S, a, x and y are respectively the contents (atomic ratios) of X, C and O, and α is a ratio of (Me1-aXa) to (N1-x-yCxOy), meeting 0.1≦a≦0.65, 0≦x≦0.1, 0≦y≦0.1, and 0.85≦α≦1.25; and the X-ray diffraction of the hard coating having a peak intensity Ir of a (111) plane, a peak intensity Is of a (200) plane, and a peak intensity It of a (220) plane, meeting 2≦Is/Ir, and 0.2≦It/Ir≦1, and the (200) plane having a half-value W(°)≦0.7.
