Abstract (en)
[origin: WO2008003273A2] Disclosed is a corrosion-resistant substrate (10) that is coated with a Cr(VI)-free corrosion-resistant triple-layer coating (2, 4, 5). Said substrate (10) is essentially composed of a steel or a Fe-based alloy that can be phosphated. A phosphating layer is placed directly on a bottom substrate (1) of the substrate (10), a silane layer is arranged directly on the phosphating layer (2), and an organically modified polysiloxane layer (5) is disposed directly on the silane layer (4).
