Abstract

L'invention concerne un procédé de phosphatation de la surface d'un substrat métallique par traitement par une solution de phosphatation contenant des ions nitrite dans un milieu aqueux. La solution de phosphatation passe dans une cuve d'électrolyse 15 où l'on réduit les nitrates en nitrites, tandis que l'on change la direction du courant à des intervalles de temps fixés. Maintien de la concentration désirée en ions nitrite dans la solution de phosphatation sans accumulation des ions de métaux alcalins et/ou des ions ammonium ne participant pas à la phosphatation et sans accumulation de précipités sur l'électrode.
