  1. Procédé de réalisation de couches superficielles sur des aciers réfractaires et également résistant à la corrosion, notamment austénitiques, par dépassivation des surfaces d'acier, de préférence dans un bain électrochimique, et par nitruration gazeuse, caractérisé en ce que, immédiatement après la dépassivation, les surfaces sur lesquelles la couche superficielle doit être formée seront revêtues galvaniquement d'une couche de fer, et la nitruration gazeuse à réaliser ensuite sera effectuée dans une atmosphère sans additifs de dépassivation.
