Description

Gegenstand der Erfindung ist ein Verfahren zum Färben von Oberflächen aus Aluminium oder Aluminiumlegierungen. Das Verfahren besteht darin, daß eine Oberfläche aus Aluminium oder einer Aluminiumlegierung einer Behandlung als Anode in einem elektrolytischen Bad unterworfen wird, um eine anodische Schicht darauf herzustellen, aind daß dann die Oberfläche mit einem Stoff oder mit Stoffen behandelt wird, die in Verbindung mit der anodischen Schicht einen gefärbten Überzug auf dem Metall bilden.The invention relates to a method for coloring surfaces made of aluminum or aluminum alloys. The method consists in making a surface made of aluminum or an aluminum alloy a treatment as an anode in an electrolytic bath is subjected to to make an anodic layer on it, and then cover the surface with a Fabric or treated with substances that are in conjunction with the anodic layer form a colored coating on the metal.

Dieses Verfahren zur Färbung von Alumi-This method of coloring aluminum

!5 nium liefert sehr viel bessere Ergebnisse als diejenigen, die man bei Versuchen erreicht hat, einen Überzug von Aluminiumoxyd zu färben, der auf dem Metall durch andere Verfahren als durch die Behandlung als Anode hergestellt worden ist. Die gefärbte Schicht haftet viel fester an dem Metall und ist gleichmäßiger in der Farbe als die nach den erwähnten anderen Verfahren erhaltene Schicht. Die erheblich verbesserte Farbwirkung kann auf die erhöhte Wirksamkeit der anodischen Schicht in ihrer Fähigkeit zur Absorption anderer Stoffe zurückgeführt werden. Diese Wirksamkeit ist um so größer, je kürzer vorher die Behandlung als Anode stattgefunden hat.! 5 nium gives much better results than those that have been achieved in attempts to coat them with aluminum oxide color produced on the metal by processes other than treatment as an anode. The colored one Layer adheres much more firmly to the metal and is more uniform in color than that layer obtained by the other methods mentioned. The vastly improved Color effect can be due to the increased effectiveness of the anodic layer in its ability be returned to the absorption of other substances. This effectiveness is greater, the shorter before the treatment than Anode has taken place.

Ein besonders zur Herstellung wirksamer Schichten geeignetes Verfahren zur anodischen Behandlung ist in dem Patent 413875 beschrieben.A particularly suitable method for producing effective layers for anodic Treatment is described in patent 413875.

Das Färbeverfahren kann darin bestehen» daß man den durch anodische Behandlung seiner ganzen Oberfläche oder eines Teils davon genügend vorbereiteten Gegenstand bei gewöhnlicher Temperatur in eine wäßrige Lösung des Farbstoffs von beispielsweise 0,1 Prozent Stärke eintaucht, bis die gewünschte Farbstärke erreicht ist. Beispielsweise kann man eine Blaufärbung erhalten,, indem man mit Anthrazenblau oder Anthrachinonblau färbt und eine Rotfärbung, indem man mit Alizarinrot S färbt. Im allgemeinen sind die Ergebnisse um so besser, je kürzere Zeit nach der anodischen Behandlung die Färbung vorgenommen wird.The dyeing process can consist of anodic treatment a sufficiently prepared object on all or part of its surface ordinary temperature in an aqueous solution of the dye of for example 0.1 percent strength is immersed until the desired color strength is achieved. For example you can get a blue coloration, by using anthracene blue or anthraquinone blue stains and a red stain by staining with alizarin red S. In general, the shorter the results, the better Time after the anodic treatment the coloring is made.
