- B) providing an application system for applying a metallic layer to the at least one surface of the metallic substrate;
- C) providing at least one plasma generator and/or at least one corona system within the application system;
- D) cleaning the coatable surface of the metallic substrate;
- E) applying, with the application system, at least one metallic layer containing a second metal selected from the group consisting of titanium, hafnium and zirconium, or a second metal alloy selected from the group consisting of alloys of titanium, hafnium and zirconium, onto the coatable surface of the metallic substrate;
- F) treating, by plasma treatment and/or corona treatment, the coatable surface of the metallic substrate or the at least one metallic layer applied to the coatable surface of the metallic substrate according to step E);
- G) treating the at least one metallic substrate or the metallic layer applied to the coatable surface of the metallic substrate with at least one organosilicon compound by way of plasma polymerization to form a polysiloxane layer;
- H) treating, by plasma treatment and/or corona treatment, the polysiloxane layer formed according to step G);
- I) applying a conversion layer onto the treated polysiloxane layer formed according to step H);
