Abstract

Die Erfindung betrifft ein Verfahren zur Erzeugung einer korrosionsschützenden Überzugsschicht, wobei eine zu behandelnde Oberfläche mit einer wässrigen Behandlungslösung in Kontakt gebracht wird, die Chrom(III)-lonen und mindestens eine Phosphatverbindung enthält, wobei das Verhältnis der Stoffmengenkonzentration von Chrom(III)-Ionen zur Stoffmengenkonzentration der mindestens einen Phosphatverbindung (bezogen auf Orthophosphat berechnet) zwischen 1 : 1,5 und 1 : 3 liegt. Durch das Verfahren wird der Korrosionsschutz metallischer, insbesondere zinkhaltiger, mit Konversionsschichten versehener Oberflächen verbessert. Dabei werden die dekorativen und funktionellen Eigenschaften der Oberflächen erhalten oder verbessert. Außerdem werden die bekannten Probleme beim Einsatz von Chrom(VI)-haltigen Verbindungen oder von Nachbehandlungen mit Polymerdispersionen vermieden.
