Abstract (en)
[origin: WO2016071399A1] The invention relates to a method for producing an anti-corrosion coating for hardenable steel sheet, wherein at least two metal layers are deposited, one after the other, on the steel substrate, wherein one metal layer is a layer made of zinc or based on zinc and the other layer is a layer made of a metal that is formed having Zn or Fe intermetallic base metal phases and having a higher oxidation potential than Zn, namely Ni, Cu, Co, Mn or Mo, or is a layer based on said metals, and an anti-corrosion layer for hardenable steel sheets.
