Claims (4)

  1. Verfahren zur Verringerung der galvanischen Korrosion eines ersten Teils aus weniger edlem Metall in einer Anordnung mit einem zweiten Teil aus edlerem Metall wenn die Anordnung einem Elektrolyten ausgesetzt wird, wobei das montierte erste Teil aus weniger edlem Metall eine Oberfläche in Kontakt mit einer exponierten Oberfläche des zweiten Teils aus edlerem Metall hat, aufweisend den Schritt des Behandelns der exponierten Oberfläche des zweiten Teils aus edlerem Metall mit einem Metall, das mit dem ersten Teil aus weniger edlem Metall galvanisch verträglicher ist als das zweite Teil aus edlerem Metall mit dem ersten Teil aus weniger edlem Metall galvanisch verträglich ist, vor dem Montieren des ersten Teils aus weniger edlem Metall an das zweite Teil aus edlerem Metall, wodurch an der exponierten Oberfläche des zweiten Teils aus edlerem Metall und zwischen dem ersten Teil aus weniger edlem Metall und dem zweiten Teil aus edlerem Metall eine Schutzschicht gebildet wird, wobei das zweite Teil aus edlerem Metall im Wesentlichen aus Kupfer besteht, das erste Teil aus weniger edlem Metall im Wesentlichen aus Aluminium besteht und das Behandlungsmetall ein Metall aufweist, das ausgewählt ist aus der Gruppe, die aus Aluminium, einer Silizium enthaltenden Aluminiumlegierung, einer Zink enthaltenden Aluminiumlegierung, Zink, Zinn, Magnesium, Gallium, Cadmium, Blei und Kombinationen davon besteht.
  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Anordnung ein Wärmeaustauscher ist, bei dem das zweite Teil aus edlerem Metall ein Wärmeübertragungsrohr ist und das erste Teil aus weniger edlem Metall mindestens eine Metallrippe ist, die an die Außenoberfläche des Wärmeübertragungsrohrs montiert ist.
  3. Verfahren nach Anspruch 1 oder Anspruch 2, bei dem der Behandlungsschritt ein Beschichtungsverfahren beinhaltet, das aus einem Heißtauchverfahren, einem Elektroplattierungsverfahren, einem Anstreich- bzw. Lackierverfahren oder einem Diffusionsbeschichtungsverfahren ausgewählt ist.
  4. Verfahren nach einem vorangehenden Anspruch, bei dem die Schicht aus Behandlungsmetall eine Dicke von zwischen 0,0001 inch und 0,002 inch (2,5 bis 51 µm) hat.
