Description

Verfahren zum vakuumdichten Verbinden von Keramikteilen mit Metallteilen Es ist vorgeschlagen worden, auf keramische Teile zunächst ein Metallpulver aufzubringen, alsdann diese Auftragung unter Erhaltung ihres porigen Gefüges aufzusintern und schließlich mittels eines hochschmelzenden Lots, das ohne Legierungsbildung das Metall des porigen Überzugs benetzt und von ihm aufgesaugt wird, die Keramikteile miteinander oder mit anderen Teilen vakuumdicht zu verbinden. Als Metallpulver ist die Verwendung von Wolfram, Molybdän oder Rhenium, als Lot Silber, Kupfer oder Hartlot vorgeschlagen worden. Es besteht nun häufig bei diesen Verbindungen das Bedürfnis, die vakuumdichte Verbindungsstelle vor mechanischen Beanspruchungen zu schützen. An sich würde es naheliegen, die Keramikteile und die Metallteile zu diesem Zweck derart auszubilden, daß sie allein durch Zusammenschrauben oder. durch ein anderes mechanisches Verfahren einen ausreichenden Halt bekommen und die Berührungsstelle erst nachträglich zu dichten. Dieses Verfahren ist jedoch unzweckmäßig, da die erforderliche maßgenaue Bearbeitung der Teile sehr teuer ist.Process for the vacuum-tight connection of ceramic parts with metal parts It has been proposed to first apply a metal powder to ceramic parts, then sinter this application while maintaining its porous structure and finally by means of a high-melting solder which, without the formation of an alloy, forms the Metal of the porous coating is wetted and absorbed by it, the ceramic parts to connect with each other or with other parts in a vacuum-tight manner. As metal powder is the use of tungsten, molybdenum or rhenium, as solder silver, copper or hard solder has been proposed. With these connections there is now often the need to protect the vacuum-tight connection point from mechanical stresses. In itself it would make sense to use the ceramic parts and the metal parts for this purpose to be trained in such a way that they are simply screwed together or. by another mechanical method get a sufficient grip and the point of contact to be written afterwards. However, this method is inconvenient because the required dimensionally accurate machining of the parts is very expensive.

. Diese Schwierigkeit wird bei dem Verfahren gemäß der Erfindung dadurch überwunden, daß die Metallteile vor oder bei dem Löten durch ein elektrothermisches Stauchverfahren derart verformt und der Gestalt des Keramikkörpers angepaßt werden, daß sie mechanisch fest verankert sind. Dabei können die Metallteile unmittelbar zwischen den Stromzuführungselektroden zusammengestaucht werden. Ein besonders sicherer Halt der Metallteile an den Keramikteilen wird mit diesem Verfahren erzielt, wenn in den Keramikteilen an der Stauchungsstelle Aussparungen, -Nuten od. dgl. vorgesehen sind, die der Metallteil beim Fließvorgang ausfüllen soll. Das Verlöten des Metallteils mit dem Keramikteil kann entweder in einem Arbeitsgang mit dem Stauchen oder erst später erfolgen. Dieses zuletzt genannte Verfahren hat den besonderen Vorteil, daß eine mechanische Beanspruchung der Lötstelle nahezu völlig vermieden wird.. This difficulty is exacerbated in the method according to the invention overcome that the metal parts before or during the soldering through a electrothermal upsetting process so deformed and the shape of the ceramic body be adapted so that they are mechanically firmly anchored. The metal parts are compressed directly between the power supply electrodes. A This process provides a particularly secure hold of the metal parts on the ceramic parts achieved when recesses, grooves in the ceramic parts at the compression point Od. The like. Are provided that the metal part is to fill during the flow process. That Soldering the metal part with the ceramic part can either be done in one operation with upsetting or later. This last-mentioned procedure has the particular advantage that a mechanical stress on the solder joint almost is completely avoided.
