Abstract

Método para producir un recipiente de circonio o de aleación de circonio para combustible nuclear, siendo dicho recipiente resistente al agrietamiento y la figuración por corrosión de fatiga, durante la utilización del reactor, estando caracterizado dicho método porque incluye las operaciones que consiste en: a) atacar químicamente la superficie interna de dicho recipiente, b) decapar la superficie atacada de dicho recipiente para eliminar solamente el material adherido de manera floja, c) oxidar la superficie interna de dicho recipiente para producir en él un revestimiento de óxido de circonio, d) limpiar la superficie oxidada de dicho recipiente para eliminar sustancialmente la totalidad de la materia extraña que puede llevar, e) activar la superficie oxidada de dicho recipiente para formar en él una capa metálica por un procedimiento no eléctrico, y f) poner en contacto la superficie activada de dicho recipiente con una solución de formación de capa metálica sin electricidad para depositar en ella una capa metálica.
