Abstract: PURPOSE:To perform electrolytic treatment of Ti-based metal without separately and newly providing a treating device for Ti by intactly utilizing an electrolytically treating device of Al and Al alloy in the case of coloring Ti and Ti alloy by electrolytic treatment. CONSTITUTION:In the case of coloring a member made of Ti or Ti alloy by anodic oxidation, an electrolytically treating device of a member made of Al and Al alloy is intactly utilized. Firstly, the member made of Ti and Ti alloy is decreased and purified by immersing this member in 70g/l HNO3 aq. soln. at 20 deg.C for 5 minutes. Then both an etching treatment stage due to an NaOH aq.soln. in an electrolytic treatment installation of Al alloy and a desmutting stage due to an H2SO4 aq.soln. are omitted. Anodic treatment is performed in 150g/l H2SO4 aq. soln. and a colored film of blue is formed. Successively boiled water treatment is performed in 10g/l nickel acetate aq.soln. at 100 deg.C for 30 minutes to seal the fine holes in the colored film and thereby this colored film is finished. The electrolytically treating device of Al can be intactly utilized. Electrolytic coloring treatment of a small amount of Ti-based metal is performed without separately necessitating the treating device for Ti.
