Zusammenfassung:The invention relates to a method for a preliminary metallizing treatment of galvanized or zinc alloy-coated steel surfaces or joined metallic parts that at least partly have zinc surfaces, in a surface treatment encompassing several process steps. In the disclosed method, metallic coats of especially a maximum of 100 mg/m2 of molybdenum, tungsten, cobalt, nickel, lead, tin, and/or preferably iron are produced on the treated zinc surfaces. Another embodiment of the invention relates to an uncoated or subsequently coated metallic part which has been subjected to the disclosed preliminary metallizing treatment as well as the use of such a part for making bodies during the production of automobiles, building ships, in the construction industry, and for manufacturing white products.
