A method for the simultaneous electrolytic deposition of zinc and magnesium on a substrate made of sheet metal and a process for the preparation of a corrosion-protected coated molded part made of sheet metal

摘要

A method for the simultaneous electrolytic deposition of zinc and magnesium on a substrate (1) made of sheet metal, in particular steel sheet, in a non-aqueous solvent (4) with a pka ≧ 16, characterized in that, in the electrolytic deposition, a mg - zn - alloy is arranged on the substrate surface is formed without a heat treatment.
