Description

Großflächige Schmelzverbindung von rohr- oder plattenförmigen Metallteilen mit Glas Es ist, beispielsweise bei der Herstellung von Vakuumröhren, bekannt, Metallteile, die mit Glas luftdicht verschmolzen werden sollen, aus Chromeisen oder Nickeleisen herzustellen. Da diese Legierungen jedoch dabei der Oxydation ausgesetzt sind, wird, besonders bei Verwendung von Nickeleisen, die Schmelzverbindung leicht undicht und deshalb unbrauchbar. Man hat daher bei der Verwendung von Nickeleisen die zu verschmelzenden Nickeleisenteile mit einem Platinmantel versehen. Es sind ferner Schmelzverbindungen von Metallteilen mit Glas bekannt, deren Metallteil aus Chromnickeldraht besteht. Jedoch haben diese Einschmelzdrähte die auf sie gesetzten Erwartungen nicht erfüllt.Large-area fusion connection of tubular or plate-shaped metal parts with glass It is known, for example in the manufacture of vacuum tubes, to use metal parts, that are to be fused airtight with glass, made of chrome iron or nickel iron to manufacture. However, since these alloys are exposed to oxidation, especially when using nickel iron, the fusible link easily leaks and therefore useless. When using nickel iron, one therefore has the ones to be fused Nickel iron parts provided with a platinum jacket. They are also fusible links known of metal parts with glass, the metal part of which consists of chromium-nickel wire. However, these fuse wires did not meet the expectations placed on them.

Gemäß der Erfindung besteht bei einer großflächigen Schmelzverbindung von rohroller plattenförmigen Metallteilen mit Glas der mit dem Glas durch Ein-, An- oder Umschmelzen dicht zu verbindende Metallteil mindestens an der Einschmelzstelle aus einer Chrom-Nickel-Legierung. Chrom-Nickel-Legierungen werden bei dem Glasschmelzvorgang nicht oxydiert; sie werden in bezug auf X ichtoxydierbarkeit nur noch von den Edelmetallen übertroffen. Ihre Anwendung erleichtert durch diese Eigenschaft das Herstellen zuverlässig vakuumdichter Einschmelzverbindungen.According to the invention, there is a large-area fusion connection of tubular roller, plate-shaped metal parts with glass, which are connected to the glass through Melting or remelting of the metal part to be tightly connected at least at the melting point made of a chrome-nickel alloy. Chromium-nickel alloys are used in the glass melting process not oxidized; With regard to their non-oxidizability, they are only found in the noble metals exceeded. Their application facilitates the production reliably due to this property vacuum-tight fusion connections.

Man braucht bei der neuen Einschmelzverbindung das Metall, bevor es an Vakuumpumpen angeschmolzen wird, zum Unterschiede von dem bekannten, regelmäßig nicht von Oxyd zu befreien. Nicht nur das Einschmelzen selbst, sondern auch die weitere Bearbeitung des Werkstückes ist dadurch wesentlich erleichtert.With the new fusion connection you need the metal before it is melted on vacuum pumps, in contrast to the known, regularly not to be rid of oxide. Not just the meltdown itself, but also that This makes further processing of the workpiece much easier.

Da Chrom-Nickel-Legierung leicht entgasbar und auch in dünnen Schichten vakuumdicht ist, machen die genannten Vorzüge es für die Anwendung in Vakuumröhren besonders geeignet. Gegenüber Chromeisen bietet Chromnickel auch noch den Vorteil, daß es sich leicht schweißen und löten läßt. Man kann daher die Chromnickelteile, wie es häufig erwünscht ist, mit Teilen aus anderem Metall verbinden.As the chrome-nickel alloy is easily degassed and also in thin layers is vacuum-tight, the advantages mentioned make it suitable for use in vacuum tubes particularly suitable. Compared to chrome iron, chrome nickel also has the advantage that that it is easy to weld and solder. You can therefore use the chrome-nickel parts, connect to parts made of other metal, as is often desired.

Chromnickel läßt sich gleich gut in Rohr-, Platten- oder irgendwelcher anderen Form, auch großflächig, mit Glas verschmelzen. Als besonders geeignet erweist sich eine Chrom-Nickel-Legierung mit etwa 6o bis 9o Prozent Nickelgehalt.Chrome-nickel can be used equally well in pipe, plate or any other other shape, even over a large area, merge with glass. Proves to be particularly suitable a chromium-nickel alloy with about 6o to 9o percent nickel content.
