  • Process for the production of corrosion-protected metallic materials and materials obtainable therewith
    Patent number: 5779818
    Abstract: A process for the production of corrosion-protected metallic materials by passivation is described, in which a layer of an intrinsically conductive polymer is deposited on the metallic material, and the coated metallic material is brought into contact with oxygen-containing water until the equilibrium potential is reached, with polyaniline in particular being used as conductive polymer.
