Abstract

Die Erfindung betrifft ein Verfahren zur Abscheidung einer Zink-Nickel-Legierung aus einem Zink-Nickel-Elektrolyten, welches dadurch gekennzeichnet ist, das dem Elektrolyten zur Erweiterung des anwendbaren Stromdichtebereichs wenigstens eine aromatische Carbonsäure, deren Salze und/oder deren Derivate oder wenigstens eine aliphatische Carbonsäure, deren Salze und/oder deren Derivate, oder wenigstens eine aromatische und/oder aliphatische Carbonsäure, deren Salze und/oder deren Derivate zugegeben werden. Ferner wird ein für dieses Verfahren geeigneter Elektrolyt angegeben. Das erfindungsgemäße Verfahren ermöglicht es in vorteilhafter Weise, daß brauchbare Zink-Nickel-Legierungen über einen weiten Stromdichtebereich abgeschieden werden können, so daß auch die Beschichtung von profilierten Werkstücken möglich ist. Dabei kann mit einem ammoniumfreien Elektrolyten gearbeitet werden, was in vorteilhafter Weise die Belastung der Abwässer verringert.The invention relates to a method for depositing a zinc-nickel alloy from a zinc-nickel electrolyte, which is characterized in that the Electrolytes for extending the applicable current density range at least an aromatic carboxylic acid, its salts and / or their derivatives or at least one aliphatic carboxylic acid, its salts and / or derivatives thereof, or at least one aromatic and / or aliphatic carboxylic acid, the Salts and / or their derivatives are added. Furthermore, one for this Method specified suitable electrolyte. The inventive method allows advantageously that useful zinc-nickel alloys over a wide current density range can be deposited, so that the Coating of profiled workpieces is possible. It can with a ammonium-free electrolytes are worked, which advantageously the Reduced load on the wastewater.
