Description
Verfahren zum Vernickeln, Versilbern usw. von Gegenständen aus Leichtmetallen oder solche enthaltenden Legierungen. Die Versilberung, Vernickelung oder Vergoldung von Gegenständen aus Leichtmetallen oder Leichtmetallegierungen auf galvanischern Wege trifft bekanntlich auf die Schwierigkeit, daß solche Gegenstände ihrer Natur nach nicht geeignet sind, als Elektroden für den galvanischen Prozeß zu dienen. Es ist nun zwar bekannt, die galvanische Behandlung dadurch zu ermöglichen, daß die dieser zu unterwerfenden Gegenstände vorher mit einem aufgespritzten Mietall versehen «-erden. das sie befähigt, als Elektroden verwendet zu werden. Eine derartige Vorbehandlung erfüllt aber nur dann ihren Zweck, wenn der Überzug des Zwischenmetalles sehr sorgfältig und dicht hergestellt wird, was naturgemäß mit verhältnismäßig hohen Kosten verbunden ist. Diese Kosten beeinträchtigen die Wirtschaftlichkeit des Verfahrens nur dann nicht, wenn es sich um Gegenstände unregelmäßiger Gestalt handelt, die auf anderem Wege nicht mit einem in allen Vertiefungen und Erhöhungen der Oberfläche wirklich gut haftenden Zwischenüberzug versehen wenden können.Process for nickel-plating, silver-plating, etc., of objects made of light metals or alloys containing them. The silver plating, nickel plating or gold plating of objects made of light metals or light metal alloys on galvanic As is well known, ways encounter the difficulty that such objects of their nature are not suitable to serve as electrodes for the galvanic process. It is now known to enable galvanic treatment in that the objects to be subjected to this beforehand with a sprayed-on rental room provided «- earth. which enables them to be used as electrodes. Such a one However, pretreatment only fulfills its purpose if the coating of the intermediate metal is made very carefully and densely, which naturally involves relatively high Cost is associated. These costs affect the economics of the process only not when it is an object of irregular shape, the in any other way not with one in all depressions and elevations of the surface really well adhering intermediate coat.
Zweck der Erfindung ist nun, das bekannte Verfahren, Gegenstände aus Leichtmetall oder Leichtmetallegierungen, ehe sie als Elektroden im galvanischenProzeß verwendet werden, mit einem sie hierfür geeignet machenden Überzug eines anderen Metalles zu versehen, dann wirtschaftlicher zu gestalten, wenn es sich um gezogene oder gewalzte Gegenstände, seien es Fertig-, seien es Halbfabrikate, handelt. Gemäß der Erfindung wird dies dadurch erreicht, daß solche Zieh- oder Walzprodukte in Stab- oder R'chrenform oder anderen Profilen, bevor sie auf galvanischem Wege vernickelt, versilbert, vergoldet usw. werden, nicht, wie bisher, durch Spritzen, sondern durch Überwalzen eines Metalles mit derZwischenschicht, die z. B. aus Zink oder Kupfer besteht, versehen werden.The purpose of the invention is now to make objects from the known method Light metal or light metal alloys before they are used as electrodes in the galvanic process are used, with a coating of another that makes them suitable for this purpose To provide metal, then to make it more economical when it is drawn or rolled objects, be they finished or semi-finished products. According to the invention this is achieved in that such drawn or rolled products in Rod or R'chren shape or other profiles, before they are galvanically nickel-plated, are silver-plated, gold-plated, etc., not, as before, by spraying, but by Rolling over a metal with the intermediate layer, e.g. B. made of zinc or copper exists, be provided.
