Abstract

Die Erfindung betrifft ein Verfahren zur galvanischen Ab­ scheidung harter, anlaufbeständiger, weiß glänzender, nickel- und cobalthaltiger Überzüge mittels wässriger, saurer, Metall­ ionen und Borsäure sowie als Glanzzusatz einen aliphatischen Aldehyd und eine aromatische Carbonylverbindung und ggfls. Netzmittel enthaltender Bäder, das dadurch gekennzeichnet ist, daß man wässrige, Nickel-, Cobalt- und Cloridionen sowie Borsäure enthaltende Lösungen mit einem pH-Wert von 3,8 bis 4,2, und einem Nickel-,/Cobalt-Ionen-Verhältnis von 8:1 bis 20:1 herstellt, als Glanzzusatz eine wässrige Lösung eines ali­ phatischen Aldehyds und einer aromatischen, wasserlöslichen Carbonylverbindung im Mengenverhältnis 20:1 bis 50:1 zu­ setzt, Nickel und Cobalt enthaltende Schichten bei einer Tem­ peratur von 50 bis 55°C und einer kathodischen Stromdichte von bis zu 7A·dm⁻² unter Verwendung von Nickel- und Cobalt­ metall im Gewichtsverhältnis von 5:1 bis 10:1 als Anodenma­ terial auf für die galvanische Vernickelung geeigneten Grund­ werkstoffen galvanisch abscheidet und bei Bedarf die Gehalte der Komponenten in den Badlösungen durch Nachschärfen mit geeigneten Zusatzlösungen auf die angegebenen Werte einstellt. The invention relates to a method for galvanic Ab divorce hard, tarnish resistant, glossy white, nickel and cobalt-containing coatings by means of aqueous, acidic, metal ions and boric acid as well as an aliphatic additive Aldehyde and an aromatic carbonyl compound and if necessary. Baths containing wetting agents, characterized in that is that you have aqueous, nickel, cobalt and chloride ions as well Solutions containing boric acid with a pH of 3.8 to 4.2, and a nickel, / cobalt ion ratio of 8: 1 to 20: 1, an aqueous solution of an ali phatic aldehyde and an aromatic, water-soluble Carbonyl compound in a ratio of 20: 1 to 50: 1 sets, layers containing nickel and cobalt at a tem temperature from 50 to 55 ° C and a cathodic current density up to 7A · dm⁻² using nickel and cobalt metal in a weight ratio of 5: 1 to 10: 1 as an anode measure material suitable for galvanic nickel plating materials and the contents if necessary of the components in the bathroom solutions by resharpening with suitable additional solutions to the specified values sets.
