Abstract

Um ein Galvanisierungsverfahren bereitzustellen, mit dem leitfähige Gegenstände einfach und kostengünstig galvanisch beschichtet und gleichzeitig passiviert werden können, wird vorgeschlagen, dass ein Substrat in ein Galvanisierbad getaucht wird, das Ionen mindestens eines Metalls zur elektrochemischen Abscheidung auf der Substratoberfläche, Ionen mindestens eines Übergangsmetalles und ein Lösemittel aufweist, wobei das Substrat die Kathode einer elektro-chemischen Zelle bildet, und dass an der elektrochemischen Zelle eine Spannung angelegt wird, wodurch ein Stromfluss erfolgt, der zur Abscheidung zumindest des mindestens einen Metalls auf der Subratoberfläche führt, dass nach Abscheidung des mindestens einen Metalls der Stromfluss unterbrochen wird, und anschließend an der Kathode ein Potential erzeugt wird bzw. eine zusätzliche Elektrode aus dem Material des Substrates, die mit dem Substrat leitend verbunden sein kann, in das Galvanisierbad getaucht wird, und für einen Zeitraum beibehalten wird bzw. eingetaucht bleibt.
