Polishing & Passivation of Titanium -- ASTM A967
A. ASTM A967 [affil link] is often specified for passivation of titanium, although it is a misnomer for sure. What you are removing by "passivation" of titanium is any iron or iron oxide that may have been put on the surface in the fabrication process of the parts. Even though you do not truly passivate the titanium metal itself, you need to ...

According to ASTM A967, passivation is the chemical treatment of stainless steel with an oxidant agent, to remove free iron or other materials. The passivation baths commonly use citric and nitric acid as oxidizing agents. However, the latter generates toxic vapors that are harmful to health [22,23,24]. On the other hand, citric acid is ...
