摘要
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 technique on the coatable surface of the substrate, and (bii1) treating the metal layer from the step (bii) with at least one acidic, first aqueous system comprising at least one first compound of the second metal. An independent claim is also included for the metallic coated substrate, preferably corrosion-resistant and/or glossy metallic coated substrate comprising the substrate, at least one metallic composite protective layer, at least one partially covalently bonded polysiloxane layer, which is present optionally directly on the composite protective layer, and at least partially covalently bonded lacquer layer, which is present optionally directly on the polysiloxane layer, or the substrate, at least one metal layer comprising at least one first metal or at least one first metal alloy, the polysiloxane layer, which is optionally directly present on the metal layer, or at least partially covalently bonded lacquer layer at the metal layer, where the first metal or the first metal alloy is applied by means of evaporation- and/or sputtering technique in the form of metal layer.
