A zinciferous coated steel sheet comprises a steel sheet, a zinciferous coating layer formed on the steel sheet, a Fe-Ni-Zn-O film formed on the zinciferous coating layer, and an oxide layer formed on a surface portion of the Fe-Ni-Zn-O film. The method comprises providing an electrolyte of an acidic sulfate aqueous solution, carrying out an electrolysis treatment in the electrolyte under a current density ranging from 1 to 150 A/dm2, and carrying out an oxidation treatment to a surface of the zinciferous coated steel sheet.

Une feuille d'acier à revêtement zincifère est constituée d'une feuille d'acier, d'une couche d'un revêtement zincifère formée sur la feuille d'acier, d'une pellicule de Fe-Ni-Zn-O formée sur la couche de revêtement zincifère et d'une couche d'oxyde formée sur une portion de la surface de la pellicule de Fe-Ni-Zn-O. La méthode comprend la préparation d'un électrolyte constitué d'une solution aqueuse d'un sulfate acide, le traitement par électrolyse dans l'électrolyte à une densité de courant comprise entre 1 et 150 A/dm2, puis le traitement par oxydation d'une surface de la feuille d'acier à revêtement zincifère.
