Abstract

Procédé de traitement superficiel de surfaces protégées par un revêtement métallique et appartenant à un substrat métallique de forme quelconque, mais se présentant de préférence sous forme de tôles d'acier, caractérisé en ce que l'on utilise un bain métallique de revêtement auquel on a ajouté un ou plusieurs éléments déterminés et en ce que l'on fait subir au revêtement métallique obtenu un traitement superficiel qui a pour effet d'engendrer sur le revêtement obtenu une couche supplémentaire de protection formée de composés stables. Method for surface treatment of protected surfaces by a metallic coating and belonging to a substrate metallic of any shape, but presenting preferably in the form of steel sheets, characterized in that a metallic coating bath is used which has added one or more specific elements and in that one subjects the metal coating obtained to treatment surface which has the effect of generating on the coating obtained an additional protective layer formed of stable compounds.
