Abstract: The invention relates to a process for preparing a substrate with a multizone metallic coating comprising the steps of heating a metallic material optionally comprising a metallic outer layer having a different composition than said metallic material, to a temperature T1, depositing a coating of aluminium, magnesium, and/or zinc, and cooling down to a temperature T2 and continuing the deposition. It furthermore relates to a substrate with a multizone metallic coating obtainable with said process.

Abstract: The invention concerns a method for electrolytic coating of materials with aluminum, magnesium or aluminum and magnesium alloys. The method is characterized in that the material is pretreated by being immersed in an electrolytic solution, where it is anodized, the electrolytic coating being performed immediately after in the same electrolytic solution.

Abstract: The invention relates to a method for producing coated workpieces, which includes (a) electrodeposition of one or more layers containing at least one metal and/or metal alloy on a substrate and (b) thermal treatment of the coated substrate at a temperature of between 300° C. and 1000° C. in such a way that at least the surface layer of the substrate and the layer or layers applied in step (a) partially and/or completely interdiffuse. The invention also relates to coated workpieces produced by this method.

Abstract: The invention relates to a coated workpiece comprising a substrate, a metallic layer applied to said substrate, and a layer containing a aluminum/magnesium alloy applied to the intermediate layer. The invention also relates to a method for producing this coated workpiece.

Abstract: The invention relates to a device (1) for separating metals and/or metal alloys from metallo-organic electrolytes and depositing the same on products (7), said device comprising at least one coating section (3) for coating the products (7), at least one other treatment section (2,4), and at least one lock chamber (20,40) for introducing and discharging the products (7) into and out of the device (1) essentially without permeation of oxygen and/or humidity. The inventive device is provided with at least one siphon rinsing unit (60,61) comprising a separating element (53,54) for the gas-related separation of the other sections (2,4) of the device from the coating section (3), or for sealing said other sections (2,4) in relation to the coating section (3), and at least one hood part (5) that can be flooded with an inert gas and tightly surrounds essentially the coating section (3), the at least one siphon rinsing unit (60,61), and the at least one other treatment section (2,4).
