Abstract

L'invention a pour objet un procédé de traitement superficiel du zinc ou d'alliages de zinc, suivant lequel on plonge l'article à traiter. présentant une surface en zinc ou en alliage de zinc, dans une solution contenant de la thiourée et du tannin ou de la thiourée et de l'acide tannique. On peut également obtenir le même résultat en traitant la surface par pulvérisation. Ce procédé améliore la résistance à la corrosion et l'adhérence des pellicules de peinture.
