The anticorrosive properties of a coating autodeposited on a metal substrate are improved by contacting the autodeposited coating with an aqueous solution containing Group IIA or Group IIB metal cations (e.g., calcium or zinc cations) and phosphate anions prior to curing. The rinse solution is preferably acidic and can be prepared, for example, from calcium nitrate and an oxy acid of phosphorus or zinc dihydrogen phosphate. Optionally, the rinse solution also includes an accelerator such as hydroxylamine.

Il est possible d'améliorer les propriétés anticorrosives d'un revêtement déposé automatiquement sur un substrat métallique en mettant ledit revêtement en contact avec une solution aqueuse renfermant des cations métalliques de Groupe IIA ou de Groupe IIB (tels que des cations de calcium ou de zinc) et des anions phosphate avant durcissement. De préférence acide, la solution de rinçage peut être obtenue, par exemple, à partie de nitrate de calcium et d'un oxyacide de phosphore ou d'un phosphate dihydrogène de zinc. De plus, cette solution de rinçage peut éventuellement renfermer un accélérateur tel qu'une hydroxylamine.
