Abstract

L'invention concerne un bain de galvanisation ainsi qu'un procédé de dépôt cathodique de revêtement d'alliage zinc-nickel. Selon ledit procédé, le bain contient, comme agent complexant, au moins une polyéthylènamine. Par addition d'un arylsulfonate tel que du cumolsulfonate ou du xylènesulfonate, on augmente la solubilité de l'agent complexant, ou bien on réduit son dépôt local au niveau de la cathode. On obtient ainsi une augmentation de la densité de courant utilisable et du rendement en courant par dépôt de couches de galvanisation homogènes et la durée de travail nécessaire est réduite.
