Description

Verfahren zur Herstellung von Metallanoden für galvanische Zwecke. Bei der Ausführung galvanischer Arbeiten. insbesondere von Vernickelungen, hat sich gezeigt, daß Gußanoden sich verhältnismäßig leicht lösen und infolgedessen bei derselben Stromstärke mehr Metall als die Walzanoden in das Bad abgeben. Dadurch wird das Bad jedoch leicht alkalisch, und es entstehen schlechte Niederschläge. Die Walzanoden lösen sich verhältnismäßig schwer, weil sie dichter im Gefüge sind als die Gußanoden, so daß das gah-anische Bad sauer und metallarm wird.Process for the production of metal anodes for galvanic purposes. When performing galvanic work. especially of nickel plating, has become shown that cast anodes dissolve relatively easily and consequently with the same Amperage emits more metal than the rolling anodes into the bath. This will make that However, the bath is slightly alkaline and poor precipitation occurs. The rolling anodes dissolve with relative difficulty because they are more dense in structure than the cast anodes, so that the Gahani bath becomes acidic and poor in metal.

Infolgedessen werden im normalen Betrieb in der Regel Gußanoden und Walzanoden gleichzeitig verwendet, während man in Sonderfällen entweder Gußanoden oder Walzanoden benutzt. Die gleichzeitige Benutzung zweier Anodenarten ist natürlich umständlich und verteuert das Vernickelungsverfahren erheblich und bedingt trotzdem nicht die erwarteten Vorzüge. Dieser Mißstand wird gemäß der Erfindung durch Verwendung einer gehämmerten Anode beseitigt, welche die Vorzüge der Guß- und Walzanode in sich vereinigt, ohne deren ungünstigen Eigenschaften zu besitzen.As a result, cast anodes and are usually in normal operation Rolling anodes are used at the same time, while in special cases either cast anodes are used or rolling anodes are used. The simultaneous use of two types of anodes is natural cumbersome and expensive, the nickel plating process considerably and still conditional not the expected benefits. This deficiency is made use of in accordance with the invention a hammered anode eliminated, which the advantages of the cast and rolled anode in unites without possessing their unfavorable properties.

Die gehämmerte Anode wird zw eckmäßigerweise durch Hämmern einer Gußanode von solcher Beschaffenheit hergestellt, welche diese Bearbeitungsweise der Anode ermöglicht. Durch das Hämmern entsteht ein ganz anderes Metallgefüge wie durch das Walzen und infolgedessen eine gleichmäßigere Dichte der Anode als bei der gewalzten Anode. Die Metallabgabe der gehämmerten Anode gemäß der Erfindung liegt etwa zwischen der Gußanode und der Walzanode, ist also derart, daß das Bad weder alkalisch noch sauer und metallarm wird. Infolgedessen entsteht ein Nickelüberzug, welcher sowohl bezüglich seiner Dichte, seines Gefüges und seiner Haltbarkeit den mittels einer Gußanode und einer Walzanode erzeugten Niederschlag wesentlich übertrifft. Das Vernickeln mit einer gehämmerten Anode gemäß der Erfindung ist naturgemäß demjenigen mit einer Gußanode allein oder einer Walzanode allein nach jeder Richtung hin weit überlegen.The hammered anode is used by hammering a cast anode made of such a quality that this method of working the anode enables. Hammering creates a completely different metal structure than that Rolling and, as a result, a more uniform density of the anode than that of the rolled one Anode. The metal release of the hammered anode according to the invention is approximately between the cast anode and the roller anode, is such that the bath is neither alkaline nor becomes acidic and poor in metal. As a result, a nickel plating is formed, which both with regard to its density, its structure and its durability the means of a Cast anode and a rolling anode generated precipitation significantly exceeds. The nickel plating with a hammered anode according to the invention is naturally that with a Cast anode alone or a roller anode alone is far superior in every direction.

Die Erfindung erstreckt sich nicht lediglich auf Nickelanoden, sondern auch auf Metallanoden anderer Art.The invention extends not only to nickel anodes, but rather also on metal anodes of other types.
