Abstract:
A transition metal nitride is obtained by a nitriding treatment of a surface of a base material including a transition metal or an alloy of the transition metal, and the transition metal nitride has a crystal structure of an M4N type and a crystal structure of an ε-M2˜3N type, and is formed over a whole area of the surface of the base material and continuously in a depth direction from the surface.
