"Passivation and Testing of Titanium"



2005

I am in the process of developing a passivation system for a small medical device company in the Midwest. I have experience with passivation and testing of stainless steels. I am looking for information on passivation and testing for Titanium, especially testing after the passivation process. I have acquired most of the ASTM and other industry standard on passivation and testing, but none mention Titanium. Any suggestions?

Titanium is naturally passive and the reason you cannot find a specification for the passivation of titanium is probably that there isn't one.

If you are worried about iron contamination after machining or shot blasting then you could try using a 50% nitric acid dip for 15 minutes.

Ed,
Brian is right, so-called passivation of titanium is normally just the removal of iron contamination. Citric acid formulations can be used for this as well. Let us know if we can help.
