Method for producing a corrosion resistant, glossy, metallic coated substrate, the metallic coated substrate, and its use

Producing corrosion-protected and/or glossy metallic or non-metallic metal-coated substrate, comprises (a) providing at least one substrate (1) with a partially metallic coated surface, (b) applying a metallic composite protective layer (11) comprising a first metal or a first metal alloy and a second metal, (c) silanizing the composite protective layer from the step (b) by treatment with alkaline second aqueous system to form at least one polysiloxane layer (13) directly on the composite protective layer, and (d) applying a lacquer layer directly on the polysiloxane layer from the step (c). Producing corrosion-protected and/or glossy metallic or non-metallic metal-coated substrate, comprises (a) providing at least one substrate (1) with at least partially metallic coated surface, (b) applying at least one metallic composite protective layer (11) comprising at least one first metal comprising aluminum, manganese, magnesium or zinc, or a first metal alloy comprising steel, stainless steel, magnesium alloy and an aluminum alloy as a main component and at least one second metal and/or at least one oxidically bound second metal comprising zirconium, titanium or hafnium as a minor component present dispersed in the main component or the main component and the minor component and (c1) silanizing the composite protective layer from the step (b) by treatment with at least one alkaline, second aqueous system to form at least one polysiloxane layer (13) directly on the composite protective layer, and (d) applying at least one lacquer layer directly on the polysiloxane layer from the step (c) or (a1) providing at least one substrate with at least one at least partially metallic coated surface, (b1) applying at least one metal layer comprising at least one first metal comprising aluminum, manganese, magnesium or zinc, or at least one first metal alloy comprising steel or stainless steel, magnesium alloy and aluminum alloy on the coatable surface of the substrate by means of evaporation- and/or sputtering technique, (c1) silanizing the metal layer from step (b1) by treatment with at least one, preferably alkaline second aqueous system to form at least one polysiloxane layer directly on the metal layer, and (d1) applying at least one lacquer layer directly on the polysiloxane layer from the step (c1). The step (b) comprises (vii) applying at least one metal layer comprising at least one first metal or first metal alloy by means of evaporation- and/or sputtering techniqu
