  • Bodies or body parts which often contain components made of aluminum and / or their alloys in addition to components made of steel and possibly galvanized steel, are subjected to a conversion chemical pretreatment, such as phosphating, before they are painted.

Abstract

L'invention concerne un procédé pour prétraiter chimiquement des surfaces métalliques, constituées au moins partiellement de surfaces d'acier, avant l'application d'un revêtement organique. Ce procédé consiste à mettre en contact les structures métalliques avec une solution de phosphatation qui contient 0,3 à 3 g/l d'ions Zn(II), 5 à 40 g/l d'ions phosphate ainsi qu'au moins un composé de titane et/ou de zircon dans des proportions telles que la teneur totale en Ti et/ou en Zr se situe dans une plage comprise entre 1 et 1000 mg/l. Lorsque la teneur totale en Ti et/ou en Zr est au moins égale à 10 mg/l, il est possible de renoncer à un rinçage passivant. Les autres surfaces, en aluminium, ne sont pas phosphatées, mais revêtues d'une couche de conversion contenant du Ti et/ou du Zr, lors du traitement au moyen de la solution de phosphatation ou lors d'un traitement ultérieur passivant.
