Description

Verbundwerkstof f ■*Composite material ■ *

Die Neuerung betrifft einen Verbundwerkstoff, bestehend aus einer Grundschicht aus einer Aluminiumlegierung mit 0,5 bis 1,5 % Mangan, gegebenenfalls mit Zusätzen von Magnesium von 0,5 bis 3 %, Rest Aluminium mit den üblichen Verunreinigungen, auf die eine Zwischenschicht aus einer Aluminiumlegierung, bestehend aus 0,5 bis 1,5 % Zink, Rest Aluminium mit den üblichen Verunreinigungen, aufplattiert ist, auf der sich wiederum eine als Lotmaterial geeignete Schicht aus einer Aluminiumlegierung, vorzugsweise einer solchen aus 6 bis 15 % Silicium, Rest Aluminium, befindet, wobei der Verbundwerkstoff zur Plattierlötung zu verwenden ist.The innovation relates to a composite material, consisting of a base layer made of an aluminum alloy with 0.5 to 1.5 % manganese, optionally with additions of magnesium of 0.5 to 3%, the remainder aluminum with the usual impurities, on which an intermediate layer of a Aluminum alloy, consisting of 0.5 to 1.5% zinc, the remainder aluminum with the usual impurities, is plated on which in turn a layer of an aluminum alloy suitable as solder material, preferably one made of 6 to 15% silicon, the remainder aluminum, where the composite material is to be used for clad soldering.

Zu diesem Zweck hat man bisher einen zweischichtigen Verbundwerkstoff benutzt, der im wesentlichen aus einer Aluminiumlegierung mit Gehalten an Mangan besteht, auf die die Aluminiumlegierung mit Gehalten von 6 bis 13 % Silicium aufgebracht ist, wie es z.B. die deutschen Patentschriften 74-4- 952 und 84-7 396 beschreiben.A two-layer composite material has hitherto been used for this purpose used, which consists essentially of an aluminum alloy with contents of manganese, on which the aluminum alloy with contents of 6 to 13% silicon is applied, as e.g. the German patents 74-4-952 and 84-7 396 describe.

Obwohl sich dieser Werkstoff in der Praxis gut bewährt hat, gab er doch in manchen Fällen zu Beanstandungen Anlaß. Dies war insbesondere dann der Fall, wenn es auf korrosionsbeständige Plattierlötungen ankam. Hierbei zeigte sich nämlich, insbesondere bei Einwirkung aggressiver Wässer in z.B. plattiergelöteten Kühlern, daß die Lotschicht den Grundwerkstoff nicht ausreichend schützte und dieser nach längerem Gebrauch der Kühler durchlöchert wurde.Although this material has proven itself in practice, it gave rise to complaints in some cases. This was particular then the case when it came to corrosion-resistant clad soldering. It was shown, in particular, at The effect of aggressive water in e.g. plate-soldered coolers that the solder layer did not adequately protect the base material and this has been perforated after a long period of use of the cooler.

Der Neuerung liegt die Aufgabe zugrunde, diese Mängel zu vermeiden. Dies geschieht gemäß der Neuerung einmal dadurch, daß als Grundwerkstoff auch eine magnesiumhaltige Legierung in Betracht kommt, während weiterhin, was von ausschlaggebender Bedeutung ist,The innovation is based on the task of avoiding these deficiencies. According to the innovation, this happens because an alloy containing magnesium can also be used as the base material, while continuing, which is of the essence,

neuerungsgemäß ein drei- oder mehrschichtiger Werkstoff vorgeschlagen wird, der zwischen dem Grundwerkstoff und der Lotplattierschicht eine Zwischenschicht aus einer Aluminiumlegierung mit den oben angegebenen Gehalten an Zink aufweist.According to the innovation, a three-layer or multi-layer material is proposed between the base material and the solder plating layer has an intermediate layer made of an aluminum alloy with the zinc contents specified above.

Versuche haben ergeben, daß dieser Werkstoff in plattiergelöteten Gegenständen, wie z.B. Kühlern, nicht nur erheblich korrosionsbeständiger gegenüber aggressiven Medien ist, sondern die Zwischenschicht elektrochemisch das Kernmaterial vor weiteren Angriffen
schützt. Die Folge hiervon ist eine erhöhte Lebensdauer der plattiergelöteten Gegenstände, wie Kühler oder sonstige mit Wasser in Berührung kommende plattiergelötete Gegenstände. Zudem verbessert die zinkhaltige Zwischenschicht die Herstellungsmöglichkeit des
lotplattierten Materials, und zwar in doppelter Hinsicht: Einmal
wird zwischen der Grundschicht und der Zwischenschicht eine überraschend gute Haftung erzielt, zum anderen haftet die Lotplattierschicht auf der Zwischenschicht stärker als bei den bisherigen
lotplattierten Werkstoffen auf der Grundschicht. Dadurch wird ebenfalls die Herstellung des Werkstoffes durch Walzschweißen erleichtert, was sich wiederum in geringerem Ausschuß bemerkbar macht.
Tests have shown that this material is not only significantly more corrosion-resistant to aggressive media in solder-plated objects, such as coolers, but that the intermediate layer is electrochemically the core material from further attack
protects. The consequence of this is an increased service life of the clad-soldered objects, such as coolers or other clad-soldered objects that come into contact with water. In addition, the zinc-containing intermediate layer improves the manufacturing possibilities of the
solder-plated material, in two respects: once
Surprisingly good adhesion is achieved between the base layer and the intermediate layer; on the other hand, the solder plating layer adheres more strongly to the intermediate layer than with the previous ones
solder-plated materials on the base layer. This also facilitates the production of the material by roll welding, which in turn is noticeable in less rejects.

Die gemäß der Neuerung auf dem Grundwerkstoff vorgesehene Zwischenschicht und Lotplattierschicht kann entweder ein- oder beidseitig des Grundwerkstoffes vorgesehen sein.The intermediate layer provided according to the innovation on the base material and a solder plating layer can be provided either on one or both sides of the base material.

Diese beiden Ausführungsformen der Neuerung sind in der beigefügten Zeichnung wiedergegeben.These two embodiments of the innovation are attached Drawing reproduced.

In Fig. 1 ist mit 1 der Grundwerkstoff bezeichnet, beispielsweise ein Blech aus einer Aluminiumlegierung mit den oben angegebenen
Gehalten an Mangan und gegebenenfalls Magnesium. 2 bedeutet die
zinkhaltige Zwischenschicht, während 3 die Lotplattierschicht,
bestehend aus einer Aluminiumlegierung mit den oben aufgeführten
Gehalten an Silicium ist.
