摘要:
Beschrieben wird ein pyrophosphathaltiges Bad zur cyanidfreien Abscheidung von Kupferlegierungen auf Substratoberflächen, umfassend ein Umsetzungsprodukt eines sekundären Monoamins mit einem Diglycidylether. Das Elektrolytbad eignet sich zur galvanischen Abscheidung von glänzenden weißen, ebenen und einheitlichen Kupfer-Zinn-Legierungsüberzügen.
摘要:
The present invention is related to a nickel electroplating bath for depositing a decorative nickel coating on a substrate to be treated characterized in that the electroplating bath comprises at least a nickel ion source, at least one amino acid and/or at least one carboxylic acid, which is not an amino acid; wherein the total concentration of the amino acid(s) is ranging from 1 to 10 g/l, wherein the total concentration of carboxylic acid(s), which is/are not an amino acid, is ranging from 10 to 40 g/l; wherein the electroplating bath is free of boric acid; wherein the total concentration of the nickel ions is ranging from 55 to 80 g/l; and wherein the nickel electroplating bath has a chloride content ranging from 7.5 to 40 g/l. The present invention is also related to a method for depositing a nickel coating on a substrate to be treated; and the use of such an inventive nickel electroplating bath for depositing a bright, semi-bright, satin, matte or non-conductive particle containing nickel coating by conducting such a method.

The invention relates to methods and plating baths for electrodepositing a dark chromium layer on a workpiece. The trivalent chromium electroplating baths comprise sulphur compounds and the methods for electrodepositing a dark chromium layer employ these trivalent chromium electroplating baths. The dark chromium deposits and workpieces carrying dark chromium deposits are suited for application for decorative purposes.
