Description

Verfahren zur elektrolytischen Herstellung hochglänzender Nickelüberzüge Die Erfindung betrifft ein Verfahren zur Herstellung hochglänzender Nickelüberzüge durch Elektrolyse.Process for the electrolytic production of high-gloss nickel coatings The invention relates to a method for producing high-gloss nickel coatings by electrolysis.

Es wurde schon vorgeschlagen, das Entstehen glänzender Metallniederschläge durchZusatzvonKolloiden, wie Leim, Gelatine, Dextrin, Tragant usw., zu dem Elektrolyten zu begünstigen. Diese Zusätze dürfen dein Nickelbad aber nur in verhältnismäßig geringen Mengen beigefügt werden, wenn sie keine schädliche Wirkung auf dieses ausüben ;ollen.It has already been suggested that shiny metal deposits be formed by adding colloids such as glue, gelatin, dextrin, tragacanth etc. to the electrolyte to favor. Your nickel bath may only use these additives in proportion added in small amounts if they do not have a harmful effect on it ; ollen.

Es ist auch bekannt, dein Nickelbad aromatische Sulfonsäuren oder deren Salze zuzusetzen.It is also known to give your nickel bath or aromatic sulfonic acids to add their salts.

Die bisher bekannten Glanzbildner haben den Nachteil, daß sie nur dann brauchbare Ergebnisse liefern, wenn das Nickelbad eine niedrige Temperatur hat und die Stromdichte. in ihm gering ist. Demgegenüber lassen die als Zusätze zum Nickelbad zu verwendenden Glanzbildner der Erfindung nicht nur eine hohe Temperatur des Nickelbades (über .4o° C), sondern auch eine hohe Stromdichte bis etwa io Amp./dcm= zu und erzeugen nicht nur hochglänzende, sondern auch weiche Metallniederschläge.The previously known brighteners have the disadvantage that they only then give usable results when the nickel bath is at a low temperature has and the current density. is little in him. In contrast, leave them as additives for the nickel bath to be used brighteners of the invention not only a high temperature of the nickel bath (over .40 ° C), but also a high current density of up to about 10 Amp./dcm= and produce not only high-gloss, but also soft metal deposits.

Nach der Erfindung werden den Nickelbädern zur Verbesserung der Glanzbildung mehrwertige ungesättigte Alkohole, insbesondere dreifach ungesättigte Alkohole, zugesetzt. Als Ausführungsbeispiel des vorgenannten Verfahrens wird der Zusatz von Dimethylacetylenylcarbinol genannt.According to the invention, the nickel baths are used to improve the gloss formation polyhydric unsaturated alcohols, in particular triunsaturated alcohols, added. The addition of Called dimethylacetylenylcarbinol.

Besonders gute Erfolge in der Glanzbildung haben sich gezeigt, wenn für jedes Liter Nickelbad etwa o,i bis i g der vorgenannten ungesättigten Alkohole pro Liter Nickelbad letzterem zugesetzt werden.Particularly good results in gloss formation have been shown when for each liter of nickel bath about o, i to i g of the aforementioned unsaturated alcohols can be added to the latter per liter of nickel bath.
