Komponent innefattande en zirkoniumlegering, förfarande för att tillverka nämnda komponent samt en nukleär anläggning innefattande nämnda komponent

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 ).
