HARD FILM AND HARD FILM FORMED BODY

摘要

PROBLEM TO BE SOLVED: To provide a hard film which has high wear resistance and excellent separation resistance and is thus capable of preventing separation for a long time, and to provide a hard film-formed body which is provided with the hard film.

SOLUTION: A hard film 1 has a structure that is configured of: a first mixture layer 1a which is mainly composed of Cr and WC and is directly formed on a surface 2a of a base material 2; a second mixture layer 1b which is mainly composed of WC and DLC and is formed on the first mixture layer 1a; and a surface layer 1c that is mainly composed of DLC and is formed on the second mixture layer 1b. The first mixture layer 1a is a layer where the Cr content decreases and the WC content increases continuously or in stages from the base side toward the second mixture layer side. The second mixture layer 1b is a layer where the WC content decreases and the DLC content increases continuously or in stages from the first mixture layer side toward the surface layer side. The hydrogen content in the second mixture layer 1b is 10-45% by atom.
