Abstract

The invention relates to a process for producing a support component having a surface catalyst structure, in which a pulverulent skeleton material comprising a mixture of materials in certain mixing ratios depending on the application is applied to the support component and subsequently the soluble constituents are leached using alkali or acid, the application of the powder mixture being carried out by thermal spraying.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Trägerbauteils mit oberflächiger Katalysatorstruktur.The invention relates to a method for Manufacture of a carrier component with a superficial Catalyst structure.

Zur Herstellung von Blechen oder Bändern mit ober­ flächiger Katalysatorstruktur wird im Stand der Technik eine Mischung aus pulverförmigem Stütz-Skelett-Material, wie Eisen, Nickel oder Kobalt und aus pulverförmiger Raney-Legierung, z.B. auf der Basis von Eisen, Nickel, Kobalt oder Silber, auf das Ausgangsblech oder -band aufgewalzt, bei Tempera­ turen oberhalb 600°C in reduzierender Atmosphäre gesintert und mit Lauge oder Säure die lösliche Komponente der Legierung herausgelöst. Damit eine ausreichende Haftung der oberflächigen Katalysator­ struktur erzielt wird, erfolgt das Aufwalzen der vorstehend genannten Mischung unter gleichzeitiger Kaltverformung des Bleches oder Bandes mit einem Verformungsgrad von 20 bis 60% innerhalb einer Ver­ formungsstufe.For the production of sheets or strips with upper flat catalyst structure is in the state of the Technique a mixture of powder Support skeleton material, such as iron, nickel or cobalt and powdered Raney alloy, e.g. on the Base of iron, nickel, cobalt or silver on which Starting sheet or strip rolled, at tempera doors above 600 ° C in a reducing atmosphere sintered and the soluble with lye or acid Detached component of the alloy. So that one adequate adhesion of the surface catalyst structure is achieved, the mixture mentioned above with simultaneous Cold forming of the sheet or strip with a Degree of deformation of 20 to 60% within a ver formation level.

Die oberflächige Katalysatorstruktur kann eine Stär­ ke von 10 bis 300 µm aufweisen.The superficial catalyst structure can be a starch have ke from 10 to 300 microns.

Diese bekannten Verfahren sind außerordentlich auf­ wendig, da sie verschiedene Arbeitsstufen notwendig machen, nämlich das Aufbringen der Katalysator­ schicht, das Kaltwalzen, das Sintern und anschlies­ send das Auslaugen.These known methods are extremely based on manoeuvrable as they require different working levels make, namely the application of the catalyst layer, cold rolling, sintering and connecting send the leaching.

Der Erfindung liegt die Aufgabe zugrunde, die be­ kannte Verfahrensweise zu vereinfachen und zu einer bessere metallurgische Eigenschaften aufweisenden Katalysatorschicht zu gelangen.The invention is based, to be to simplify known procedures and to a having better metallurgical properties To get catalyst layer.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object underlying the invention will solved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteran­ sprüchen erläutert.Advantageous configurations are in the Unteran sayings explained.

Mit anderen Worten ausgedrückt schlägt die Erfindung vor, daß das Aufbringen der Katalysatorschicht durch thermisches Spritzen unter Benutzung aller bekannten Verfahren erfolgt, so daß das bisher im Stand der Technik erforderliche Kaltwalzen und Sintern nicht mehr notwendig ist.In other words, the invention suggests before applying the catalyst layer by thermal spraying using all known Procedure is carried out so that the previously in the Technology does not require cold rolling and sintering is more necessary.

Um die metallurgischen Eigenschaften der aufgebrach­ ten Katalysatorschicht zu verbessern wird weiterhin vorgeschlagen, daß das Aufbringen der einzelnen Schichten graduiert erfolgt, wobei sich die Zusammen­ setzung jeder einzelnen Schicht ändert, so daß in der untersten Schicht wenig oder gar kein Metall vorhanden ist, das eine lösliche Komponente auf­ weist, während in der äußersten Schicht der Anteil des Metalls mit löslicher Komponente wesentlich höher als der Anteil des Metalls mit nicht löslicher Komponente vorhanden ist, wobei die Löslichkeit sich auf die Behandlung mit Lauge oder Säure bezieht.To the metallurgical properties of the broke up will continue to improve th catalyst layer suggested that the application of each Layers are graded, with the together setting of each individual layer changes so that little or no metal in the bottom layer is present, which has a soluble component points, while in the outermost layer the proportion of the metal with soluble component essential higher than the proportion of the metal with insoluble Component is present, the solubility relates to treatment with lye or acid.

Schließlich wird gemäß der Erfindung vorgeschlagen, daß das aus Trägerblech und durch thermisches Spritzen aufgebrachten Schichten bestehende Bauteil anschließend getempert wird, um somit ein Diffun­ dieren der beiden Metalle ineinander zu erreichen, wobei die abgestufte Zusammensetzung der einzelnen Schichten noch verbessert und der innere Aufbau ver­ stärkt wird.Finally, according to the invention, it is proposed that the carrier sheet and thermal Spray applied layers of existing component is then annealed to form a diffusion  to reach the two metals into each other, where the graded composition of each Layers improved and the internal structure ver is strengthened.

Zusammenfassend ist also festzuhalten, daß nicht nur das Arbeitsverfahren erleichtert, sondern auch der Aufbau der Katalysatorschicht verbessert und indivi­ duell den Anforderungen angepaßt werden kann.In summary, it should be noted that not only the working process, but also the Structure of the catalyst layer improved and indivi duel can be adapted to the requirements.
