Abstract

Procédé de dépôt d'une couche noire anticorrosive sur un alliage de zinc qui consiste à traiter l'alliage de zinc dans une première étape du procédé par une solution aqueuse acide de Cr3+ contenant un ou plusieurs agents complexants et à traiter l'alliage de zinc ainsi passivé dans une deuxième étape du procédé par une suspension aqueuse contenant des polymères organiques et des oxydes métalliques anticorrosifs et des pigments noirs. L'invention vise aussi une couche anticorrosive noire à deux states sur un alliage de zinc, la première strate de la couche anticorrosive ayant un oids (en Cr) de 1 à 4 mg/dm2.
