Description
Verfahren zur Herstellung von Schmuckgegenständen. Es ist bekannt, daß sogenannte elektroplattierte Schmuckgegenstände, selbst bei hoher Auflage des Edelmetalls, beim Tragen sich bedeutend rascher abnutzen wie ' sogenannte dublierte Gegenstände, das sind solche, die ihren Edelmetallüberzug vor der Verarbeitung durch Aufschweißen erhalten. Der Grund für .diese rasche Abnutzung liegt in der großen Weichheit oder Edelmetalle in reinem Zustande.Process for the manufacture of jewelry items. It is known, that so-called electroplated jewelry items, even with high numbers of Precious metal, when worn, wear out significantly faster than so-called duplicated Objects that are those that have their precious metal plating before processing Welding received. The reason for this rapid wear and tear is due to the large size Softness or precious metals in a pure state.
Diesem Übelstande kann man wohl bis zu einem gewissen Grad ,dadurch abhelfen, daß man geeignete Legierungen elektrolytisch niederschlägt, doch reicht auch bei Schmuckgegenständen, welche auf diese Weise einen legierten Edelmetallüberzug erhalten haben, die Haltbarkeit der Edelmetalfauflage nicht an diejenige mit aufgeschweißtem Edelmetall heran.To a certain extent, this can be avoided by doing this help to deposit suitable alloys electrolytically, but is enough even with jewelry, which in this way an alloyed precious metal coating received, the durability of the precious metal plating does not match that with the welded on Precious metal.
Das vorliegende Verfahren bezweckt, die vorgenannten Übelstände zu beheben:, und zwar dadurch, daß die fertigen oder nahezu fertigen Schmuckgegenstände mit einem Edelmetallüberzug aus Gold oder Silber auf galvanischem Wege überzogen und zum Schlusse auf besondere, im nachstehenden beschriebene Weise legiert werden, wodurch ein Fertigfabrikat erzielt wird, dessen Oberfläche der Abnutzung mindestens ebensolchen Widerstand entgegensetzt wie das unter Druck aufgeschweißte Edelmetall.The purpose of the present proceedings is to remedy the abovementioned evils fix:, namely by the fact that the finished or almost finished jewelry items Electroplated with a precious metal coating made of gold or silver and finally alloyed in a special way described below, whereby a finished product is obtained, the surface of which is at least subject to wear as opposed to the same resistance as the noble metal welded on under pressure.
Ein aus den beliebigen, in der Schmuckwarenindustrie gebräuchlichen Edel- oder Unodelmetallen oder deren Legierungen hergestellter Schmuckgegenstand wird mit einer Gold- oder Silberauflage versehen. Zwecks Erzielung der obengenannten Legierung wird nun der Gegenstand gemäß der Erfindung in einer -sauerstofffreien Atmosphäre oder im Vakuum auf eine je nach dem zu erzielenden Feingehalt gewählte Temperatur von 5oo bis 6oo° erhitzt. Dadurch wird eine von vornherein genau bestimmbare Legierung der Metalloberfläche (Dubleemetall) erzielt und eine Oberfläche des Schmuckgegenstandes geschaffen, die sich bei .der Weiterbehandlung (Polieren usw.) sowie bei späteren Reparaturen, beim Löten, Glühen usw. genau wie homogene Edelmetallegerungen benimmt.Any of those commonly used in the jewelry industry Jewelery made from precious or non-precious metals or their alloys is provided with a gold or silver plating. In order to achieve the above Alloy now becomes the article according to the invention in an oxygen-free one Atmosphere or in a vacuum to one chosen depending on the fineness to be achieved Temperature from 5oo to 6oo ° heated. This makes one that can be precisely determined from the outset Alloy of the metal surface (Dubleemetall) achieved and a surface of the jewelry item created, which will result in further treatment (polishing, etc.) as well as in later Repairs, soldering, annealing, etc. behaves just like homogeneous precious metals.
Die durch dieses neue Verfahren erzielbaren Fabrikationsvorteile gegenüber der Verarbeitung von sogenannten dublierten Metallen sind äußerst zahlreich; so werden die Dublierungskosten der Bleche, Drähte, Scharniere usw. erspart, jeglicher Abfall von Edelmetall bei der Roh- wie Fertigfabrikation wird verhütet und es wird die Herstellung solcher Muster ermöglicht, die bislang in aufgeschweißtem Rohmaterial nur bei Verletzung der Edelmetalloberfläche möglich war.The manufacturing advantages that can be achieved by this new process the processing of so-called duplicated metals are extremely numerous; so the duplication costs of sheets, wires, hinges etc. are saved, any Waste of precious metal in raw and finished production is prevented and it will the production of such patterns enables the previously in welded raw material was only possible if the precious metal surface was damaged.
