Abstract (en)

[origin: WO03056055A1] According to the invention, an anti-corrosion coating on a magnesium workpiece can be generated, whereby a halide salt is applied in at least one surface coat to the workpiece, with a thermodynamic stability less than a salt formed from magnesium and the same halide, such that, during the application of the halide salt to the workpiece and/or under the influence of a corrosive medium the salt with magnesium is formed.
