摘要：
A method for the preliminary treatment against corrosion of a plurality of metallic components, in which dragging of water-soluble phosphates from an acid passivation process using water-dissolved phosphates as the active components, e.g. a phosphating process, into the dip coating treatment stage, is effectively prevented.
