Title:
MEMBER COATED WITH HARD FILM AND JIG FOR FORMING
Document Type and Number:
WIPO Patent Application WO/2010/084982
Kind Code:
A1
Abstract:
A member coated with a hard film, the coated member being obtained by forming a nitride layer on a surface of an iron-based alloy base material and then forming a nitride film, carbide film, or carbonitride film on the nitride layer by PVD (Physical Vapor Deposition).  When Fe-N compounds in the nitride layer are examined for X-ray diffraction peaks at incidence angles (θ) and diffraction angles (2θ) with the surface of the base material, the proportion of the peak intensity for (111) of the γ’ phase (Fe4N) to the peak intensity for (101) of the ε phase (Fe2-3N) is 60% or lower.
