I have a titanium part that is glass bead peaned prior to passivation. The bead blast media is also used on 300, 400 series stainless steels as well as 14-4 PH and MP35N materials.
Will the passivation remove any imbedded particles in the titanium from the other materials or is there still a chance for cross contamination?

Delly, If the passivation will not remove the transferred contamination, can you use fresh beads on the Ti? But I think I understand your question to mean that hopefully you can reuse the same beads if your assured the passivation will remove the cross contamination.

Thanks Delly

If you need a procedure for checking for surface contamination, take a look at ASTM A380, Standard Practice for Cleaning, Descaling and Passivation of Stainless Steel Parts, Equipment and Systems.
Section 7 (Inspection after Cleaning) gives a couple of tests for detection of iron contamination. We have used the Ferroxyl Test very succesfully on titanium alloys.
