Beschreibung
Zusammenfassung:	Disclosed herein is a vanadium-based coating film having a high film hardness. When subjected to X-ray diffraction using Cu Ka radiation, the vanadium-based coating film has peaks at diffraction angles 2¸ of 29.9 degrees or more but 30.3 degrees or less, 33.2 degrees or more but 33.6 degrees or less, and 69.8 degrees or more but 70.6 degrees or less, and has a maximum intensity at a diffraction angle 2¸ of 33.2 degrees or more but 33.6 degrees or less. This vanadium-based coating film has a film hardness HV of 3500 to 5000, and therefore has a hardness higher than those of conventional vanadium-based coating films.
