摘要

[Problems];To provide a technique for surface hardening treatment of mechanical structural parts that are excellent in mechanical strengths, such as contact pressure strength, abrasion resistance and bending fatigue strength in comparison with conventional techniques.;[Means for solving];A quenched steel member, wherein a hard nitride layer is formed on the surface of a steel material and, as a layer over the layer, an inorganic compound layer containing at least one metal oxide selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, W, Mo and Al is formed.
