hard bright gold plating

These baths are used for cyanide electrolyte for decorative gold-plating of non-ferrous metals and precious metal alloys with differing deposition alloy and thus colour. The relatively thin layers are characterised by being very hard. The spectrum of materials to be coloured can be considerably increased by a preparatory application of the pre-plating gold bath AC3 (item No. 695655), e.g. steels.

Hard bright gold-plating baths are used in traditional electroplating units. A surface which has been
degreased is essential. By contrast to gold plating, the gold colouring bath only leaves a thin layer of gold of a maximum of 0.1 to 0.25 mµ.
