    Abstract: Die Erfindung betrifft ein alkalisches Galvanisierungsbad sowie ein Verfahren zur kathodischen Abscheidung von Zink-Nickel-Legierungsüberzügen, wobei das Bad ein oder mehrere Polyethylenamine als Komplexbildner enthält. Durch Zugabe eines Arylsulfonats wie etwa Cumolsulfonat oder Xylensulfonat wird die Löslichkeit des Komplexbildners erhöht, bzw. seine lokale Abscheidung an der Kathode vermindert. Hierdurch wird eine Erhöhung der anwendbaren Stromdichte und der Stromausbeute unter Abscheidung homogener Galvanisierungsschichten ermöglicht und die benötigte Arbeitsdauer verkürzt.
