Abstract

Pour réduire les problèmes opérationnels tels que la formation de tartre et de dépôt rencontrés dans les processus de phosphatation effectués à l'aide de compositions contenant du zinc et au moins un élément tel que Ni, Co ou Zn, on maintient un niveau effectif de cations fer dissous dans ces mêmes compositions.
