1) I would love to be able to get my hands on a book that can teach me a great deal more on the passivation process. Is there such a book out there? 2) We rinse parts in a closed-loop bath that is not controlled for pH or any other content parameters. Under what conditions do you need to take the acid bath step? 3) I am setting up passivation and chem film lines in a shop and am wondering what are some good resources for getting started? 4) Are there biocompatibility issues with passivating stainless steel?

Would the acids produce a phosphate coating, or is it necessary to have a cathodic metal in the solution to conversion coat?

Is this happening because the nickel is too low and the chlorine is now too harsh against the chrome and other component into the 2101? What would you recommend to strip the chrome without any effect on the duplex stainless surface?
