ABSTRACT:
A hard coating film excellent in wear resistance and seizure resistance for coating a forming tool of a Cr-containing iron-base alloy includes a first coating layer A of a thickness between 1 and 10 μm formed on the forming tool and a second coating layer B of a thickness between 2 and 10 μm overlying the coating layer A. The first coating layer A is a film of Crl-xMx(BaCbNl-a-b) meeting conditions expressed by expressions: 0≦x≦0.7, 0≦a≦0.2 and 0≦B≦0.5 , where M is at least one element among W, V, Mo, Nb, Ti and Al, x is atomic ratio of M, a is atomic ratio of B and b is atomic ratio of C, and the second coating layer B is a film of Til-X-Y-ZCrXAlYLZ(BBCANl-A-B) meeting conditions expressed by expressions: 0≦1-X-Y-Z≦0.5, 0<X≦0.5, 0.4≦Y≦0.7, 0≦Z≦0.15, 0≦A≦0.5, and 0≦B≦0.2, where L is at least either of Si and Y, X is atomic ratio of Cr, Y is atomic ratio of Al, Z is atomic ratio of L, A is atomic ratio of C and B is atomic ratio of B.
