Patent ID: 8017226

Claim:
A hard film-coated member, comprising: a base material including an iron base alloy containing Cr; a first film layer formed with a film thickness of 1 to 10 μm on the surface of the base material; and a second film layer formed with a film thickness of 2 to 10 μm on the surface of the first film layer, wherein the first film layer comprises Cr 1-a-b M a B b (C c N 1-c ), in which M is one or more elements selected from W, V, Mo, Nb, Ti, and Al, and a, b, and c each denote the atomic ratio, and satisfy the following relations: 0≦a≦0.7; 0≦b≦0.15; 0≦c≦0.5; and 0.5≦1a-b, and, the second film layer comprises Nb 1-d-e-f Cr d Al e L f (C g N 1-g ), in which L is one or more elements selected from Si, Y, and B, and d, e, f, and g each denote the atomic ratio, and satisfy the following relations: 0.05≦1-d-e-f≦0.5; 0.05≦d≦0.5; 0.4≦e≦0.7; 0≦f≦0.15; and 0≦g≦0.5.
