A. "Passivation" of titanium alloys is a misnomer, of course. However, many in the industry do call it passivation. What you are really doing is cleaning the surface and removing iron compounds and other active metals from the surface to prevent any corrosion.

ASTM F86 is the specification that is used for this application. It sites only nitric acid at this time (2002), but citric acid systems are being added to the specification because they work very well and are safe and easy to use.
