| titleOfInvention | BATH FOR GALVANIC DEPOSITION OF A WEAR RESISTANT GOLD ALLOY AND METHOD FOR DEPOSITION OF A WEAR RESISTANT GOLD ALLOY USING THIS BATH |
| abstract | The electroplating gold alloy baths disclosed for decorative coatings have a pH of 0.75 to 2.75. The gold is present as alkali-metal auricyanide, while the alloying element is present as a water-soluble salt and the acid matrix is selected from the group comprising oxalic acid, citric acid, sulphamic acid, phosphoric acid, nitric acid and hydrochloric acid. The alloys can be deposited on electronic and decorative substrates in a relatively short time. The colour of the coating can be determined by variation of the pH and the choice of the alloying element. Wear-resistant coatings are obtained if the alloying element is cobalt or nickel. These baths contain nitric acid and an alkali-metal nitrate or phosphoric acid and, optionally, a wetting agent, and they have a pH not exceeding 0.75. The coatings are notable for an improved wear resistance, lower contact resistance and a lower content of concomitantly deposited carbon. |
