  Galvanisches Bad zum Überziehen von   Metallgegen8tänden   mit anderen Metallen. 



   Es handelt sich bei der Erfindung um das Niederschlagen von Gold, Silber, Platin, Kupfer, Zink, Nickel, Zinn und Blei oder von Legierungen dieser Metalle auf Metallflächen ; insbesondere kommt das Galvanisieren von Gegenständen aus Eisen oder Stahl in Betracht. 



   Gemäss der Erfindung wird der Elektrolyt in der Weise hergestellt, dass das Salz des niederzuschlagenden Metalles bzw. die betreffenden Metallsalze in einer wässerigen Lösung von Natrium- oder Kaliumglyzerinborbenzoat gelöst werden. Das Natriumpräparat ist vorzuziehen. 



   Borax wird beim autogenen Schweissverfahren und in ähnlichen Fällen als ein Reduzier-oder Flussmittel in ausgedehntem Masse verwendet, da er Metalloxyde leicht löst. In ähnlicher Weise wirkt auch das Reduziermittel in einem Elektrolyten lösend auf eine oxydierte und daher für die Galvanisierung nachteilige Fläche ein, ohne dass die Fläche selbst angegriffen wird. 



   Natriumglyzerinborbenzoat kann dadurch hergestellt werden, dass man gleiche Gewichtsteile von Natriumborglyzerid und Natriumborbenzoat mischt. Beide Präparate sind leicht erhältlich. 



   Der Elektrolyt für das Niederschlagen eines einzigen Metalls kann dadurch hergestellt werden, dass man ein Salz oder Salze des Metalls in einer wässerigen Lösung von   Natriumgtyzerinborbenzoat   z. B. im Verhältnis von 2,'3 Salz zu   /j   Lösung auflöst ; soll mit einer   Metallcgierung galvanisiert werden,   so werden zunächst die   Lösungen   der verschiedenen Metallsalze in dem Reduziermittel einzeln hergestellt, wie eben beschrieben, und die einzelnen Lösungen darauf miteinander vermischt, wobei sich die Mischungs-und   Mengenverhältnisse   nach den Metallen der Legierung richten.

  Galvanic bath for coating metal objects with other metals.



   The invention concerns the deposition of gold, silver, platinum, copper, zinc, nickel, tin and lead or of alloys of these metals on metal surfaces; in particular, the electroplating of objects made of iron or steel comes into consideration.



   According to the invention, the electrolyte is produced in such a way that the salt of the metal to be deposited or the metal salts concerned are dissolved in an aqueous solution of sodium or potassium glycerol borobenzoate. The sodium supplement is preferable.



   Borax is used extensively in the autogenous welding process and in similar cases as a reducing agent or flux because it readily dissolves metal oxides. In a similar way, the reducing agent in an electrolyte has a dissolving effect on an oxidized and therefore disadvantageous surface for electroplating, without the surface itself being attacked.



   Sodium glycerol borobenzoate can be made by mixing equal parts by weight of sodium boroblyceride and sodium borobenzoate. Both preparations are readily available.



   The electrolyte for the deposition of a single metal can be prepared by placing a salt or salts of the metal in an aqueous solution of sodium tycerol borobenzoate, e.g. B. in the ratio of 2, '3 salt to / j solution dissolves; If a metal alloy is to be electroplated, the solutions of the various metal salts in the reducing agent are first prepared individually, as just described, and the individual solutions are then mixed with one another, the mixing and quantity ratios depending on the metals of the alloy.
