Component including a zirconium alloy, a method for producing said component, and a nuclear plant including said component

摘要

The present invention relates to a component (1) comprising an element (2), which contains zirconium or a zirconium alloy and which has a surface (3) on which a corrosion protective layer (4) is formed, the oxide layer (4) comprising zirconium oxide. The component (1) is intended to be in an oxidising environment (6) and said oxide layer (4) has an outer surface (5) towards said oxidising environment (6). The element (2) comprises a layer (10), that borders said surface (3) and comprises hydrogen and at least one metal from the group of lanthanum elements and/or from the group platinum metals and/or yttrium which in its elemental form or as an oxide have the ability to effectively dissociate oxygen and H₂O. The invention also relates to a method for manufacturing the component (1) and a nuclear facility comprising the component (1).
