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.

Abstract: The invention relates to a method for producing a coating for absorption of neutrons produced in nuclear reactions of radioactive material which can be applied in an economically feasible and simple manner, increases the effectivity of absorption, enables greater variability of base material used and variability of shape of said shielding elements and in particular the production of lighter shielding elements with at least the same absorption quality. The invention also relates to a method for producing a coating for absorption of neutrons produced in nuclear reactions of radioactive materials. At least one part of a shielding element consisting of base material is provided at its surface designed therefore with a layer made of an element with a high neutron capture section and a metallic element in a dispersion bath. Said metallic element can be deposited by electrolytic or autocatalytic means.
