Description

Verfahren zur Erzeugung galvanischer Überzüge auf Bletallegierungen. Seit Jahren ist es ein die ganze Leichtmetalle verarbeitende Industrie beschäftigendes Problem, zum Zwecke der Vernickelung, Versilberung, Vergoldung o. dgl. bestimmte galvanische Überzüge auf solchen Metallegierungen herzustellen, die, wenn sie unmittelbar als Elektroden fürgalvanische Verfahren verwendet würden, sich bis zu einem gewissen Grade selbst zerstören. Solche Metallegierungen sind z. B. Leichtmetallegierungen, insbesondere des Magnesiums, wie sie unter dem Namen »Elektron« im Handel befindlich sind. Es ist ausgeschlossen, Elektron unmittelbar auf galvanischem Wege z. B. zu vernickeln. Aber auch alle sonstigen Versuche zur Herstellung .einer Vernickelung, Versilberung usw. sind vollkommen gescheitert.Process for the production of galvanic coatings on metal alloys. For years it has been an industry that deals with the entire light metal processing industry Problem, for the purpose of nickel plating, silver plating, gold plating or the like. Certain to produce galvanic coatings on such metal alloys, which, if they are immediately used as electrodes for electroplating processes to some extent Grade destroy yourself. Such metal alloys are e.g. B. light metal alloys, in particular of magnesium, as it is commercially available under the name "electron" are. It is not possible to use electrons directly by galvanic means, e.g. B. to nickel-plating. But also all other attempts to produce a nickel plating, Silver plating etc. have failed completely.

Die Erfindung selbst löst nun erstmalig dieses Problem dadurch, daß auf den z. B. aus Elektronmetallhergestellten Gegenstand zunächst nach einem der bekannten Metallspritzverfahren ein Überzug eines anderen Metalls aufgebracht wird, der gegebenenfalls nach darauffolgender mechanischer Bearbeitung, z. B. Polieren oder sonstiger; die Dichte verbessernden Behandlung, die Legierung fähig macht, unmittelbar als Elektrode für den galvanischen Prozeß verwendet zu werden. Für die Vernickelung würde im allgemeinen ein entsprechend starker und dichter, durch Spritzen hergestellter Überzug aus Kupfer zweckmäßig sein. Dieser Überzug schützt die Legierung vollkommen gegen eine Zersetzung oder Zerstörung und gestattet, daraus hergestellte Gegenstände genau so auf galvanischem Wege zu vernickeln wie einen ganz aus Kupfer hergestellten Gegenstand.The invention itself solves this problem for the first time in that on the z. B. made of electron metal article first after one of the known metal spraying processes a coating of another metal is applied, possibly after subsequent mechanical processing, z. B. Polishing or other; density improving treatment making alloy able to be used directly as an electrode for the galvanic process. For the Nickel plating would generally be a correspondingly thicker and denser one, by spraying produced coating made of copper be expedient. This coating protects the alloy completely against decomposition or destruction and allowed to be produced from it Electroplating objects in exactly the same way as one made entirely of copper manufactured item.

Das Material des aufzuspritzenden Überzuges richtet sich naturgemäß nach den beabsichtigten galvanischen Prozessen.The material of the coating to be sprayed on depends naturally according to the intended galvanic processes.
