いという事で汎用性に乏しかった。In addition, as an example of the multicolor method, Japanese Patent Application Laid-Open No. 62-705
There is a method disclosed in Publication No. 99. [Problems to be Solved by the Invention] However, the coloring caused by painting peels off easily, and the colored pattern caused by anodizing treatment exhibits an interference color of each woodcutter color, and is extremely Since it was thin, it had the disadvantage of poor abrasion resistance. For example, in the technique disclosed in Japanese Patent Application Laid-open No. 62-70599, the anodic oxide film is limited to the concave portions to prevent deterioration of wear resistance, but the hardness of the anodic oxide film (HV450)
The wear resistance was lower than that of the titanium nitride layer (HV900) produced by the nitriding method, and it had the disadvantage of being inferior in wear resistance, and it lacked versatility because it could only be used in concave areas.
