ABSTRACT:
A hard film and a hard film-coated material having better wear resistance and sliding performance (due to lower friction coefficients) than conventional surface coating layers, wherein the hard film includes at least one covering layer A and at least one covering layer B stacked one over the other, both having a thickness of 5 to 100 nm. The covering layer has a composition represented by the formula M(BaCbN1−a−b), where M denotes one or more elements selected from W, V, Mo, and Nb, and a and b denote the atomic ratio of B and C, respectively, as defined below. 0≦a≦0.3 . . . (1A), and 0≦b≦0.5 . . . (2A). Covering layer B has a composition represented by the formula Ti1−x−yCrxAlySiz(C1−ANA) where x, y, z, and A denote the atomic ratio of Cr, Al, Si, and N, respectively, as defined below. 0≦1−x−y≦0.5 . . . (1B), 0≦x≦0.5 . . . (2B), 0.4≦y≦0.7 . . . (3B), 0≦z≦0.15 . . . (4B), and 0.5≦A≦1 . . . (5B).
