Description

Verfahren zum Aufbringen eines Schwermetallüberzuges äuf einen Aluminiumleiter mittels des Spritzverfahrens Es ist bekannt, Aluminiumleiter mit einem gut leitenden Schwermetallii!berzug, z. B. mit einem Kupferüberzug, zu versehen, insbesondere wird ein solcher Überzug an Kontaktstellen zur Erzielung eines guten Stromüberganges angewandt. Zum Aufbringen des gut leitenden Metalls ist das Met,allspritzverfahren sehr geeignet.Method of applying a heavy metal coating to an aluminum conductor By means of the spraying process It is known to produce aluminum conductors with a good conductive Heavy metal coating, e.g. B. to be provided with a copper coating, in particular such a coating on contact points is used to achieve good current transfer applied. The metal spraying process is used to apply the highly conductive metal very suitable.

Das Aufspritzen von Schwermetallen, insbesondere Kupfer, auf Aluminium und dessen Legierungen ergibt aber nach den üblichen Methoden keine festhaftenden Niederschläge.The spraying of heavy metals, especially copper, onto aluminum and its alloys, however, do not result in firmly adhering ones according to the usual methods Rainfall.

Nach der Erfindung wird daher vor dein Bespritzen die Oberfläche des Aluminiums mit einem Aluminiumlot überzogen, auf das dann der Kupferüberzug mit der Spritzpistole aufgebracht wird. Derartig aufgespritzte Überschläge haften fest und geben auch einen einwandfreien Stromübergang vom Kupferbelag zum Aluminium.According to the invention, therefore, the surface of the Aluminum is coated with an aluminum solder, on which the copper coating is then applied the spray gun is applied. Such sprayed flashovers adhere firmly and also provide a perfect current transfer from the copper coating to the aluminum.

Es ist an sich bekannt, auf Aluminium eine Silberschicht aufzubringen und hierauf einen Schwermetallüberzug aufzuspritzen. Dabei handelt es sich jedoch nicht um einen elektrischen Leiter. Außerdem ist das Verfahren viel komplizierter, da sich Aluminium nicht mit Silber löten läßt. Dazu kommt noch, daß Silber bedeutend teurer ist als Aluminiumlot. Schließlich gewährleistet auch eine Lötverbindung bei elektrischen Leitern stets einen einwandfreien Stromübergang an den Verbindungsstellen.It is known per se to apply a silver layer to aluminum and spray a heavy metal coating on it. But that is what it is not an electrical conductor. In addition, the procedure is much more complicated, since aluminum cannot be soldered with silver. In addition, silver is important is more expensive than aluminum solder. Finally, a soldered connection also ensures electrical conductors always a perfect current transfer at the connection points.
