Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Herstellung eines als Abschirmung einsetzbaren rohrförmigen Bauteils anzubieten, welches die Vorteile verschiedener Metalle vereinigt.outgoing From this prior art, the invention is based on the object a method for producing a usable as a shield tubular To offer components that the advantages of different metals united.
Das erfindungsgemäße Verfahren zur Herstellung eines derartigen als Abschirmung einsetzbaren rohrförmigen Bauteils sieht als ersten Verfahrensschritt vor, dass in einer Schmelzform mit einem rohrförmigen Hohlraum ein in axialer Richtung erster Abschnitt des Hohlraums mit einem nieder schmelzenden Metall gefüllt wird, wobei in einem weiteren Arbeitsschritt in dem in axialer Richtung sich anschließenden Abschnitt des Hohlraums ein mittels eines Pulvers aus hoch schmelzendem Metall hergestellter rohrförmiger poröser Rohling eingebracht wird, und wobei weiterhin in dem in axialer Richtung sich daran anschließenden Abschnitt des Hohlraums ein nieder schmelzendes Metall bereitgestellt wird, bevor der Inhalt der Schmelzform im Vakuum für eine zur teilweisen Schmelzdiffusion in den porösen Rohling ausreichende Zeit auf eine ausreichend hohe Temperatur gebracht wird, und wobei schließlich nach dem Abkühlen der Schmelzform ein rohrförmiges Bauteil zur Weiterverarbeitung entnommen wird.The inventive method for producing such a tubular component which can be used as a shielding provides as a first step that in a melt mold with a tubular one Cavity in the axial direction of the first portion of the cavity is filled with a low-melting metal, wherein in a further step in the axially adjacent portion of the cavity a manufactured by means of a powder of high-melting metal tubular porous Blank is introduced, and wherein further in the in axial Follow this direction Section of the cavity provided a low-melting metal is before the contents of the mold in vacuum for a partial melt diffusion into the porous blank sufficient time is brought to a sufficiently high temperature, and being finally after cooling the mold is a tubular one Component is removed for further processing.
Ein nach dem erfindungsgemäßen Verfahren hergestelltes als Abschirmung in einer Vakuumschaltröhre einsetzbares rohrförmiges Bauteil aus Metall verfügt zwischen zwei Endbereichen aus einem ersten Metall über einen mittleren Abschnitt verfügt, der ein zweites Metall mit einer Schmelztemperatur aufweist, die höher als die Schmelztemperatur des ersten Metalls ist, und nach dem oben beschriebenen Verfahren hergestellt ist.One produced by the process according to the invention as a shield in a vacuum interrupter usable tubular component made of metal between two end regions of a first metal over a middle section has, having a second metal having a melting temperature, the higher than the melting temperature of the first metal is, and after the above described method is made.
Dabei ist es besonders von Vorteil, wenn die Endbereiche aus Kupfer bestehen und zwischen den Endbereichen ein mittlerer Abschnitt aus einer Kupfer und Chrom enthaltenden Legierung vorhanden ist.there it is particularly advantageous if the end areas consist of copper and between the end portions, a middle portion of one Copper and chromium containing alloy is present.
Auf diese Weise wird eine Abschirmung realisiert, die im relevanten Kontaktspaltbereich aus Kupfer-Chrom besteht. Bei einer derartigen Gestaltung zeichnet sich die Abschirmung im Kontaktspaltbereich durch eine hohe Abbrandfestigkeit gegenüber reinem Kupfer aus. Weiterhin ergibt sich der Vorteil der verminderten Leitfähigkeit zur Reduzierung von Wirbelströmen und damit geringerer Wechselwirkungen des Schaltplasmas mit der Abschirmung. Außerhalb des Kontaktspaltbereichs kann das dort vorliegende Kupfer besonders einfach bearbeitet und verformt werden.On In this way, a shield is realized, which in the relevant Contact gap area consists of copper-chrome. In such a Shaping is the shielding in the contact gap area characterized by a high erosion resistance compared to pure copper. Farther This results in the advantage of reduced conductivity to reduce eddy currents and thus lesser interactions of Schaltplasmas with the Shielding. Outside of the contact gap area, the copper present there can be especially easily edited and deformed.
Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen, bei der teilweise auf die Figuren der Zeichnung Bezug genommen wird.Further Advantages and details of the invention will become apparent from the following Description of exemplary embodiments, in which reference is made in part to the figures of the drawing.
