Abstract (en)
[origin: WO2004053203A2] The invention relates to a method for the electrolytic deposition of magnesium on a substrate consisting of sheet metal (1) comprising a zinc or zinc alloy coating, especially a steel sheet. The electrolytic deposition is carried out in a solvent (3a) having a lower acidity than water, especially in an essentially aprotic solvent, and the coated substrate (1) is then subjected to a heat treatment in order to create a Mg-Zn alloy phase in the zinc layer. The inventive sheet metal (1) is characterised by improved corrosion resistance with the same high surface quality and machinability as galvanised sheet metal.
