Abstract (en)
The following is a method of coloring titanium and titanium alloys through anodic oxidation in an electrolytic bath. This method is characterized by the fact that titanium and its alloys undergo a preliminary anodic treatment at a constant potential in an electrolytic bath consisting of hydrohalogen acids or salts, fluoboric, fluosilic, acetic, oxalic, tartaric, nitric, phosphoric acids and their mixtures, possibly in the presence of oxidizing agents.
