The present invention provides hard coating film which excels conventional surface coating layer in wear resistance, has lower frictional coefficient and better slideability, a material coated with the hard coating film, a die for cold plastic working, and a method for forming the hard coating film. The hard coating film according to the present invention is a hard coating film comprising (NbxM1-x)y(BaCbN1-a-b)1-y, where 0.2@x@1.0 Equation (1) 0@a@0.3 Equation (2) 0@1-a-b@0.5 Equation (3) 0.5@b=1 Equation (4) 0.4@1-y@0.9 Equation (5) [however, M denotes at least one species of elements belonging to Groups 4a, 5a, and 6a and Si and Al; x, 1-x, a, b, and 1-a-b represent respectively the atomic ratio of Nb, M, B, C and N; and y and 1-y represent respectively the ratio of (NbxM1-x) and (BaCbN1-a-b).] |
