摘要：
A titanium aluminum nitride coating having a columnar crystal structure, which is formed on a substrate, comprises high-Al TiAlN having an fcc structure, which has a composition represented by (Tix1, Aly1)N, wherein x1 and y1 are numbers meeting x1=0.005-0.1, and y1=0.995-0.9 by atomic ratio, and network-like, high-Ti TiAlN having an fcc structure, which has a composition represented by (Tix2, Aly2)N, wherein x2 and y2 are numbers meeting x2=0.5-0.9, and y2=0.5-0.1 by atomic ratio; the high-Al TiAlN being surrounded by the network-like, high-Ti TiAlN.
