Alternative process to chemical conversion coating

I am working for the aerospace industry. We are using hexavalent chromium in our chemical conversion coating process. Recently, we are looking for an alternative process that is chrome-free and meets the requirements of MIL 5541 and 81706. Is there such a chrome-free conversion coating process for the aerospace industry? Kind regards.

Hi, Gulsum. Yes, it's called TCP. Update your library to the most recent version of the specs you mentioned, because it's quite recent, and you wil see it. Good luck.

Regards,
