Description

Verfahren zum Färben von Metall-Legierungen Gegenstand der Erfindung ist ein Verfahren zur Färbung von Körpern aus gewissen Z ink-Aluminium-Kupfer-Legierungen, insbesondere solchen. die sich aus etwa g5 bis 97%, Zink. I bis 2", Aluminium und 2 bis 3 %, Kupfer zusammensetzen. Nach demn Verfahren werden zur Erzeugung einer schwarzen Färbung die vorher entfetteten Körper während einer Dauer von ungefähr Io Sekunden in ein Bad getaucht, das in ungefähr gleichen Raumteilen aus einer Lösung von Io%igem Kupfersulfat (SO4Cu) und einer Lösung von Pikrinsäure in Stärke von besteht.Process for coloring metal alloys The subject of the invention is a process for coloring bodies made of certain zinc-aluminum-copper alloys, especially those. which is made up of about g5 to 97%, zinc. I to 2 ", aluminum and Compose 2 to 3%, copper. After demn method are used to generate a black coloring the previously defatted bodies for a duration of approximately Io was immersed in a bath for seconds in approximately equal parts of the room from a solution of Io% copper sulphate (SO4Cu) and a solution of picric acid in the strength of consists.

Die Entfettung der Legierungen kann beispielsweise auf bekannte Art in einem Bad von Ätzkali oder Atznatron erfolgen.The alloys can be degreased in a known manner, for example in a bath of caustic potash or caustic soda.

kann die Entfettung auch durch eine Behandlung mnit Sandstrahl ersetzen. lach der Behandlung in dlemn Bad von Kupfersulfat und Pikrinsäure werden die Stücke mnit warmeen Wasser abgespült, getrocknet und abgebürstet. Vor oder nach der Färbung können die Stücke in geeigneter Art behandelt werden. um ihnen. abgesehen von der Fürbung. irgendein bestimmtes Aussehen zu geben. So können sie z. B. eine verzierende Ausgestaltung oder einen Glanz erhalten.can also replace degreasing with sandblasting. After treatment in a bath of copper sulphate and picric acid, the pieces become Rinsed with warm water, dried and brushed off. Before or after staining the pieces can be treated in a suitable manner. To you. apart from the Advocacy. to give any particular look. So you can z. B. a decorative one Design or receive a gloss.
