Europäische Patentanmeldung ~ A " Nr. 92 910 024.6 EU 2380 Norsk Hydro A.S. Geänderte Patentansprüche
1. Verfahren zum Verbinden von Aluminiumteilen, wobei das Verfahren die Schritte umfaßt:
Bereitstellen mindestens eines der Teile mit einer anhaftenden Oberflächenschicht aus Zink oder einer Legierung auf Basis von Zink;
Aufbringen von Flußmaterial auf zu verbindende Oberflächen der Teile;
Vormontieren der Teile;
Unterziehen der so vormontierten Teile in einem Ofen einem Erhitzen auf eine vorbestimmte erhöhte Verbindungstemperatur und Auszusetzen der Teile darin der erhöhten Verbindungstemperatur für eine vorbestimmte Zeitspanne,
dadurch gekennzeichnet, daß
zwischen den Teilen eine Schicht aus geschmolzenem Füllmaterial in Form von Zink-Aluminium-Grenzflächen-Legierungen gebildet wird, durch Diffusion mindestens eines Teils des Materials der Oberflächenschicht in das Material der Teile, wobei die Legierungen mit steigenden Temperaturen zunehmend gebildet werden.
2. Verfahren nach Anspruch 1, wobei die Oberflächenschicht eine Dicke von 2 bis 20 &mgr;&idiagr;&eegr; hat.
3. Verfahren nach Anspruch 2, wobei die Oberflächenschicht eine Dicke von 4 bis 6 &mgr;&idiagr;&eegr; hat.
4. Verfahren nach Anspruch 1, weiterhin umfassend, das Aufrechterhalten einer inerten Atmosphäre in dem Ofen.
2 0588
5. Verfahren nach Anspruch 1, weiterhin umfassend, das Aufrechterhalten einer Luftatmosphäre in dem Ofen.
6. Verfahren nach Anspruch 1, wobei die Verbindungstemperatur im Bereich von 450 bis 62O0C ist.
7. Wärmeaustauscher, insbesondere Automobilwärmeaustauscher, durch das Verbxndungsverfahren nach einem oder mehreren der vorhergehenden Ansprüche bereitgestellt,
dadurch gekennzeichnet, daß
die gelöteten Verbindungen zwischen den Aluminiumteilen vollständig durch die in situ gebildete Schicht aus Füllmaterial der Zink-Aluminium-Grenzflächen-Legierungen erreicht wird (ohne Zusatz von gesondertem Lotmaterial).
