Description

Verfahren zur Erzeugung galvanischer Überzüge auf Leichtmetallen. Es ist bisher noch ein ungelöstes Problem, Leichtmetalle, wie Aluminium, Magnesium u. dgl., auf galvanischem Wege beispielsweise zu vernickeln, zti versilbern oder zu vergolden.Process for the production of galvanic coatings on light metals. It is still an unsolved problem, light metals such as aluminum, magnesium and the like, for example to be nickel-plated by galvanic means, zti silver-plated or to gild.

Die Erfindung löst dieses Problem dadurch, (laß auf den zum Beispiel aus Aluminium hergestellten 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 verbessernder Behandlung, das Leichtmetall fähig macht, es unmittelbar alsElektrode für den galvanischen Prozeß zu verwenden. Für die Vernickelung würde im allgemeinen ein entspreche.id starker und dichter, durch Spritzen hergestellter Überzug aus Kupfer zweckmäßig sein. Gegeherienfalls könnte auch noch eine weitere ".12etallschicht aufgespritzt «-erden. Der so hergestellte ein- oder mehrfache Überzug gestattet, die so hergestellten, im wesentlichen aus Aluminium bestehenden Gegenstände genau so auf galvanischem Wege zu vernickeln wie einen ganz aus Kupfer hergestellten Gegenstand.The invention solves this problem by (refer to, for example Object made of aluminum initially by one of the known metal spraying processes a coating of another metal is applied, optionally after the subsequent mechanical processing, e.g. B. polishing or other, the density improving Treatment that makes light metal capable of using it directly as an electrode for the galvanic Process to use. For nickel plating, a corresponding ID would generally be used strong and dense, spray-made copper coating appropriate be. If necessary, another layer of metal could also be sprayed on "-earth. The single or multiple coating produced in this way allows the produced, objects consisting essentially of aluminum just as well on galvanic Nickel-plating ways like an object made entirely of copper.

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.
