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
