Abstract:CR six on the human body, especially to the skin can cause harm and become environmental problems, now chromic acid passivation film, in particular the galvanized layer chromate passivation film in Europe have been limited. The chromate passivation film performance and carried out in order to trivalent chromium chromate chromate passivation with or without replacing the development status of explained.
Keywords:passivation process  trivalent chromium  non-chromate
