ABSTRACT:
A member with alumina-based hard coating formed there-on wherein said hard coating contains nitrogen and has a composition represented by the formula (1) below:in-line-formulae description="In-line Formulae" end="lead"?Al1-xMx(O1-yNy)z  (1)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?(0≦x≦0.5, 0<y≦0.5, z>0)in-line-formulae description="In-line Formulae" end="tail"?where, M denotes at least one species of elements selected from those belonging to Group 4, Group 5, and Group 6 (excluding Cr), and such elements as Y, Mg, Si, and B.The hard coating based on γ-alumina, which is formed at temperatures no higher than 1000° C., is superior in wear resistance and heat resistance.
