DEUTSCHES PATENTAMTGERMAN PATENT OFFICE
Es sind thermisch hochbelastbare Anoden für elektrische Entladungsgefäße bekannt, die aus Eisenblech mit einem Aluminiumüberzug bestehen und zwecks Verbesserung der Strahlungseigenschaften einer Glühbehandlung bei Temperaturen von etwa 500 bis 1000'0' C unterworfen, worden sind. Es muß bei der Glühbehandlung darauf geachtet werden, daß die erwähnte obere Temperatur grenze nicht wesentlich überschritten wird, da sonst wieder eine Verschlechterung der Strahlungseigenschaften eintritt.There are thermally highly loadable anodes known for electrical discharge vessels, which consist of sheet iron with an aluminum coating and subjected to an annealing treatment at temperatures of about 500 to 1000 '0' C for the purpose of improving the radiation properties, have been. During the annealing treatment, care must be taken that the above-mentioned upper temperature limit is not significantly exceeded, otherwise the radiation properties will deteriorate again.
Das Ergebnis solcher Glühbehandlungen ist ein blaugraues Aussehen des zuvor blanken Aluminiumüberzuges infolge der Bildung einer chemischen Verbindung zwischen Eisen und Aluminium.The result of such annealing treatments is a blue-gray appearance of the previously bare aluminum coating as a result of the formation of a chemical bond between iron and aluminum.
Die Erfindung zeigt einen Weg, auf dein es möglich ist, schwarze Oberflächen zu erzielen.The invention shows a way in which it is possible is to achieve black surfaces.
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von hochbelastbaren Elektroden, insbesondere von Anoden elektrischer Entladungsgefäße, die aus. Eisenblechen mit Aluminiumauflage bestehen und vor ihrer Verwendung einer Glühbehandlung etwa zwischen. 500 und ioo6lOiC unterworfen werden. Die Erfindung besteht darin/ daß das Elektrodenmaterial nach der Glühbehandlung kurzzeitig in destilliertem Wasser gekocht wird.The invention relates to a method for producing highly resilient electrodes, in particular anodes of electrical discharge vessels, which are made from. Iron sheets with aluminum coating exist and before they are used an annealing treatment between. 500 and ioo6 lOi C are subjected. The invention consists in / that the electrode material is briefly boiled in distilled water after the annealing treatment.
Die Maßnahme nach der Erfindung gestattet die Herstellung von Elektrodenblechen, deren Gesamtstrahlung der des schwarzen. Körpers sehr naheThe measure according to the invention allows the production of electrode sheets, their total radiation that of the black. Body very close

kommt. Es empfiehlt sich, das Elektrodenmaterial nach der Glühbehandlung während der Dauer von einer halben bis zu einigen Minuten in destilliertem Wasser zu kochen.comes. It is advisable to use the electrode material after the annealing treatment for the duration of half a minute to a few minutes in distilled water.
Wenn man danach das Elektrodenmaterial noch einer Glühbehandlung unterwirft, kann man eine nach dem Kochen an sich gegebene erhöhte Gasabgabe während des Pumpprozesses verhindern,If the electrode material is then subjected to an annealing treatment, one can Prevent increased gas release after boiling during the pumping process,
. Es hat sich gezeigt, daß die mit der Erfindung erzielte Wirkung erhöht wird, wenn man das bekannte Verfahren der Glühbehandlung und des Kochens in destilliertem Wasser gemäß der Erfindung mehrmals wiederholt.. It has been shown that the effect achieved by the invention is increased if one uses the known Method of annealing and boiling in distilled water according to the invention repeated several times.
