Abstract

Chemical conversion process characterised in that it comprises the use, at the time of the actual phosphatising stage, of a zinc conversion bath containing phosphate and nitrate ions as well as ferrous or ferric ions and from approximately 21 to approximately 100 g/l of at least one organic chelating agent.
