Abstract:
Disclosed herein are a hard coating film, a material coated with the hard coating film, and a die for cold plastic working, the coating film excelling conventional surface coating layers in wear resistance as well as slidability with a low frictional coefficient.The hard coating film is characterized by a chemical composition of (VxM1-x) (BaCbN1-a-b), where 0.4≦x≦0.95 (1A) 0≦a≦0.2 (2A) 0≦1-a-b≦0.35 (3A) 0.6≦b≦1 (4A) M denotes at least one species of elements belonging to Groups 4a, 5a, and 6a and Si and Al; and x, 1-x, a, b, and 1-a-b represent respectively the atomic ratio of V, M, B, C, and N.
