Claim:
A process for treatment of metallic surfaces, the process comprising the steps of: pretreating the metallic surfaces; coating the metallic surfaces with a conversion coating by contacting the metallic surfaces with a conducting polymer dispersion consisting of a conducting polymer selected from the group consisting of polyaniline (PANI), polyethylenedioxythiophene (PEDOT) and polypyrrole (PPY) and inorganic metallic salts selected from at least one of molybdenum, magnesium, zirconium, titanium, vanadium, cerium, hafnium, silicon, aluminum, boron, cobalt and zinc in concentrations of the inorganic metallic salts between 2.0 grams/Liter and 20 grams/Liter and a pH value of between 1 and 6.0; and, drying the metallic surfaces.
