    摘要： 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.

    摘要： Consumer goods and industrial articles are electroplated with bronze layers for decorative purposes and for protection against corrosion. The electrolytes used hitherto for producing decorative bronze layers are cyanide-containing or, as in the case of baths based on organosulfonic acids, highly corrosive, or, as in the case of cyanide-free baths based on diphosphoric acid, give unsatisfactory brightness and shine. The present invention provides a nontoxic electrolyte for the electrochemical deposition of uniformly bright and shiny bronze layers and a corresponding process for the application of such decorative bronze layers to consumer goods and industrial articles, by means of which relatively thick bronze layers can also be deposited electrochemically in a satisfactory way.

    摘要： The invention relates to a modified copper-tin electrolyte which is free of toxic constituents such as cyanides or thio compounds. The invention further relates to a process for the deposition of decorative bronze layers on consumer goods and industrial articles using the electrolyte of the invention. The electrolyte comprises an additive formed from epichlorohydrin and hexamethylenetetramine and contains carbonate or hydrogencarbonate ions.
