Abstract:
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.
