摘要 |
<p>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.</p> |
