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 (MeX)(NCO), 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 (MeX) to (NCO), 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 Iof a (111) plane, a peak intensity Iof a (200) plane, and a peak intensity Iof a (220) plane, meeting 2≦I/I, and 0.2≦I/I≦1, and the (200) plane having a half-value W(°)≦0.7.
