KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft die weitere Ausgestaltung des Verfahrens nach ■Patent 183072, demzufolge zur Erzeugung von glänzenden Metallüberzügen auf anderen Metallen auf galvanischem Wege das Bad einen Zusatz erhält von Lösungen von GIycosiden, Phloroglycosidcn, Pliloroghiciden o. dgl. oder von stickstoffhaltigen Glycosiden oder deren Abkömmlingen oder anstatt dieser Substanzen von Extrakten von Pflanzen, Wurzeln oder Rinden (z. B. Althäa-Panama-, Süßholzcxtrakt usw.), welche die genannten Stofi'c oder einen derselben enthalten.The present invention relates to the further embodiment of the method according to ■ Patent 183072, therefore for production of shiny metal coatings on other metals by electroplating the bath an addition is made of solutions of glycosides, phloroglycosides, pliloroghicides o. The like. Or of nitrogen-containing glycosides or their derivatives or instead of these Substances from extracts of plants, roots or bark (e.g. Althäa-Panama-, Licorice extract, etc.), which contain the substances mentioned or one of the same.
Zweck der Erfindung ist, unter Anwendung dieses Verfahrens glänzende Niederschläge von dunkler Farbe zu erhalten. The purpose of the invention is to obtain glossy deposits of dark color using this method.
Bekanntlich werden bei manchen elektrolytischen Verfahren unbeabsichtigt unregelmäßige Niederschläge von grauer Farbe erhalten, wenn die Operation nicht in der richtigen Weise durchgeführt wird.It is known that some electrolytic processes inadvertently become irregular Precipitates of gray color are obtained if the operation is not carried out in the correct way.
Das vorliegende Verfahren betrifft nun die absichtliche Erzeugung eines gleichförmigen Metallniedcrschlagcs von rein schwarzer oder tiefblauer Farbe. Es können . so 'die verschiedenartigsten Gegenstände, beispielsweise Gewehrteile, mit einem dunklen matten Überzug versehen werden.The present method now relates to the deliberate creation of a uniform Metal deposits of pure black or deep blue color. It can . so 'the most diverse Objects, for example rifle parts, with a dark, matt coating be provided.
Das Verfahren, welches sich zwar insbesondere zur Erzeugung von Nickelniederschlägen eignet, aber auch für andere Metalle benutzt werden kann, wird in der Weise ausgeführt, daß die zu überziehenden Metallgegenstände zunächst poliert werden, daß man dann die Politur entweder durch Eintauchen in ein Säurebad oder mittels des ' Sandstrahlgebläses oder in sonstiger Weise abstumpft, die Gegenstände also mattiert, daß man sie dann in einem Bade, welches außer den üblichen Salzen eine Abkochung von Süßholzwurzel oder Süßholzwurzel selbst oder irgendeine andere der in dem Hauptpatente genannten Substanzen enthält, der Wirkung eines elektrischen Stromes von einer Spannung unterwirft, wie sie zur Erzeugung von weißem glänzenden Nickel erforderlich ist. Nachdem auf diese Weise der Niederschlag erzeugt ist, vermindert man, ohne die Gegenstände aus dem Bade zu nehmen, plötzlich die Spannung beträchtlich und führt nunmehr die Operation zu Ende.The process, which is particularly useful for generating nickel deposits suitable, but can also be used for other metals, is carried out in such a way that the metal objects to be coated are first polished, that the polishing is then either by dipping in an acid bath or by means of the sandblasting blower or in any other way dulls the objects, i.e. mattifies them, that they are then placed in a bath which, in addition to the usual salts, is a decoction of licorice root or licorice root itself or any other of those in the main patent contains the substances mentioned, subjected to the action of an electric current from a voltage such as that used to generate it of white shiny nickel is required. After the precipitate has been produced in this way, one diminishes, Without taking the objects out of the bath, the tension suddenly became considerable and now completes the operation.
Nachstehend ist ein Beispiel für "die Ausführung des Verfahrens gegeben, welches jedoch dem jeweiligen Zwecke entsprechend geändert werden kann:Given below is an example of "performing the method which however, it can be changed according to the respective purpose:
Man löst so viel Nickelsulfat und Nickelammoniumsulfat zu gleichen Teilen in Wasser auf, daß eine Lösung von 120 Be. entsteht. In dieser Badflüssigkeit löst man pro Liter 2 g glyzyrrhizinsaures Ammon auf. Die zu 5qOne dissolves so much nickel sulfate and nickel ammonium sulfate in equal parts in water that a solution of 12 0 Be. arises. In this bath liquid, 2 g of glyzyrrhizic acid ammonium are dissolved per liter. The to 5q
