Abstract
An arc-ion-plated hard coating having a composition represented by (AlTiW)NO, wherein x, y, z, a and b are numbers meeting by atomic ratio 0.6≤x≤0.8, 0.05≤y≤0.38, 0.02≤z≤0.2, x+y+z=1, 0.2≤a≤0.8, and 0.02≤b≤0.10), and having W—O bonds with substantially no Al—O bonds when identified by X-ray photoelectron spectroscopy, and having only a NaCl-type structure in an X-ray diffraction pattern.
