ABSTRACT:
Coating bath and method for cataphoretic coating of metallic iron surfaces from aqueous solutions and/or aqueous dispersions of salts of cationic film-forming agents. An additional content of metallic ions from metallic salts is dissolved in the coating bath, the potential of which in the electrolytic voltage series of the cations is higher than the potential of the iron metal surfaces.
