Title (EN) IMPROVED METHOD FOR NICKEL-FREE PHOSPHATING METAL SURFACES
(FR) PROCÉDÉ AMÉLIORÉ DE PHOSPHATATION SANS NICKEL DE SURFACES MÉTALLIQUES
(DE) VERBESSERTES VERFAHREN ZUR NICKELFREIEN PHOSPHATIERUNG VON METALLISCHEN OBERFLÄCHEN
Abstract:
(EN) The present invention relates to a method for the substantially nickel-free phosphating of a metal surface, in which a metal surface is treated with the following compositions one after the other: i) with an alkaline, aqueous cleaning agent composition, which contains at least a water-soluble silicate, and ii) with an acidic, aqueous, substantially nickel-free phosphating composition, which comprises zinc ions, manganese ions and phosphate ions. The invention also relates to the above cleaning agent composition itself and to a metal surface phosphate-coated by means of the above method and use thereof.
(FR) La présente invention concerne un procédé de phosphatation sensiblement sans nickel d’une surface métallique, selon lequel une surface métallique est traitée successivement avec les compositions suivantes : i) une composition de nettoyage aqueuse alcaline contenant au moins un silicate hydrosoluble et ii) une composition de phosphatation sensiblement sans nickel, aqueuse et acide, contenant des ions de zinc, des ions de manganèse et des ions de phosphate. L’invention concerne également la composition de nettoyage susmentionnée ainsi qu’une surface métallique revêtue de phosphate par le procédé susmentionné et son utilisation.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur im Wesentlichen nickelfreien Phosphatierung einer metallischen Oberfläche, bei dem eine metallische Oberfläche, nacheinander mit den folgenden Zusammensetzungen behandelt wird: i) mit einer alkalischen, wässrigen Reinigerzusammensetzung, welche mindestens ein wasserlösliches Silikat enthält und ii) mit einer sauren, wässrigen, im Wesentlichen nickelfreien Phosphatierzusammensetzung, welche Zinkionen, Manganionen und Phosphationen umfasst. Die Erfindung bezieht sich zudem auf obige Reinigerzusammensetzung selbst sowie auf eine mittels obigen Verfahrens phosphatbeschichtete metallische Oberfläche und deren Verwendung.
