Consumer goods and industrial articles are electro-plated with bronze layers for decorative reasons and to protect them against corrosion. The electrolytes used hitherto for producing decorative bronze layers are either cyanide-containing or, as in the case of baths based on organosulphonic acids, highly corrosive or have, as in the case of cyanide-free baths based on diphosphoric acid, unsatisfactory long-term stabilities. Electrolytes which are used for applying solderable bronze layers in the electronics industry usually contain toxic or very toxic thio compounds. The present invention provides a non-toxic electrolyte which displays long-term stability for the electrolytic deposition of decorative bronze layers and a corresponding process for the application of such decorative bronze layers to consumer goods and industrial articles. |
