Abstract

Cyanide-containing silver electrolyte for the electrodeposition of silver-graphite dispersion-hardened coatings, which contains 10-100 g/l of graphite of particle size 1-10 mu m, 0.02-5 g/l of a brightener for silver baths and 0.05-2 g/l of a wetting agent for alkaline electrolytes. The electrolyte is used, in particular, for coating relay contacts.
