A zinc phosphate-type conversion film having microfine-sized crystals is formed on metal surfaces using a conversion treatment bath that contains zinc ions and phosphate ions along with 50 to 1500 ppm of an organoperoxide conversion accelerator, and optionally surfactant. Surface-conditioning treatments can be omitted from this method. The presence of the surfactant makes possible simultaneous execution of surface cleaning and conversion treatment.

Pellicule de conversion de type phosphate de zinc comportant des cristaux de dimension super-fine, formée sur des surfaces métalliques au moyen d'un bain de traitement de conversion contenant des ions zinc et des ions phosphate ainsi que 50 à 1500 ppm d'un accélérateur de conversion organopéroxyde, et éventuellement un tensioactif. Dans ce procédé, les opérations de traitement de surface ne sont pas nécessaires. La présence du tensioactif rend possible l'exécution simultanée du nettoyage de surface et du traitement de conversion.
