Abstract: The present invention relates to a layer system for coating a substrate surface and to a method for coating a substrate surface with a corresponding layer system, the layer system comprising at least two layers. One layer is a metal-nickel-alloy layer with a metal of the group comprising tin, copper, iron, tungsten and cobalt or an alloy of at least one of said metals, and the other layer is a layer of a metal of the group comprising nickel, copper, tin, molybdenum, niobium, cobalt, chromium, vanadium, manganese, titanium and magnesium, or an alloy of at least one of said metals. The layer system according to the invention is characterized by a high mechanical stability and great corrosion resistance.
