Description

B-eder Bearbeitung vorn flächenhaften Materialien, beiispielsweisedurch Sanden; Schleifen oder Feilen, kommt es in der Regel zur Ausbildung von Spitzen. an der Oberfläche dies Materials, die beispielsweise bei &r Verwendung in elektrischen, Anordnungen aller Art zur AusM Idung besonders starker elektrischer Felder führen und somit die elektrische Festigkeit der Anlage beeinträchtigen. Andererseits kann auf d,a;s Aufrauten nicht immer verzichtet werden, da eine binrei@cherndie Haftfähigkeit angesammelter Materialien auf der Fläche oft nur ,diurch Aufrauhen gewährleistet werden kann. Diese Schwierigkeiten treten, insbesondere bei der Herstellung von Trockengleichrichtern auf, bei denn die Trägerelektroden gesandet werden müssen, so daß Spitzenausbildungen in d!-r Trägerelektrode häufig zum elektrischen Durchschlagen und damit zur Minderung oder gar Zerstörung des Gleichrichters beitragen.Either processing of flat materials, for example by Sands; When grinding or filing, points are usually formed. on the surface of this material, which is used, for example, in electrical, All kinds of arrangements lead to the development of particularly strong electric fields and thus impair the electrical stability of the system. On the other hand, can d, a; s roughening is not always dispensed with, since there is a bin-rich adhesive capacity accumulated materials on the surface often only guaranteed by roughening can be. These difficulties arise, especially in the manufacture of Dry rectifiers, because the carrier electrodes have to be sanded, so that tip formations in the carrier electrode often lead to electrical breakdown and thus contribute to the reduction or even destruction of the rectifier.

Bei der Behandlung von: Flächen aus leitendem Material kann es :sich als vorteilhaft erweisen, gegenüber @d'er arideren Anordnung ein solches Potential` zu geben, diaß sie die Elektronen anziehen.When treating: surfaces made of conductive material it can: itself turn out to be advantageous, compared to @ d'er other arrangement such a potential` so that they attract the electrons.

Auch @dde beiderseitige Bearbeitung solcher Flächen ist nach dem Verfahren in einem Arbeitsgang ermöglicht.Also @dde mutual processing of such surfaces is according to the procedure made possible in one operation.

Eine Beschleunigung dier Wirkung ist möglich, wenn die Fl'äc'hen gleichzeitig mit der Beaufschlagung der Elektronienstrahlen auch noch von im Vakuum in geringen Spuren vorhandenen aggressiven Gasen :auf chemischem Wege angegriffen werden. Besonders vorteilhaft ist eis dann, dde nach d!em Verfahren behandielten Flächen einer thermischien Nachbehandlung zu unterziehen.An acceleration of the effect is possible if the surfaces simultaneously with the application of the electron beams also from in a vacuum in small amounts Traces of existing aggressive gases: Can be attacked chemically. Particularly It is advantageous if the surfaces treated according to the method are thermally treated To undergo post-treatment.

So behandelte Flächen eignen sich besonders zur Verwendung als Trägerelektroden für elektrisch unsymmetrisch leitende Systeme. Die Figuren zeigen in zum Teil. schematischer Darstellung eine ;aufgoraarhte Fläche vor und nach der Behandllüng gemäß der Lehre .der Erfindung. In F.ig. i weist ,die Fläche noch eine sehr unregelmäßige Spitzenibilldung auf, welche entsprechen6 Fig.2 durch die Anwendung des beschriebenen Verfahrensherabgesetzt wird und somit; ein elektrisch festeres Ausgangsmaterial ergibt.Areas treated in this way are particularly suitable for use as carrier electrodes for electrically asymmetrically conductive systems. The figures show in part. more schematic Representation of a ruffled area before and after the treatment according to the teaching .the invention. In F.ig. i shows that the surface still has a very irregular tip formation which correspond to 6 Fig. 2 reduced by applying the method described becomes and thus; results in an electrically stronger starting material.
