in Tables 1, 2, and 3 show some of the characteristics of the various electroforming processes currently in use. The original process for electroforming 10k, 14k, or 18k gold utilizes cyanide based electrolytes that deposit gold copper cadmium alloys, which have a good yellow color.
The gold salt content and the conductivity of an existing bath affect the gold electroforming deposition rate. Would it be a citrate bath or a phosphate bath when the bath pH is 6 or 7? What's the theory we have for the additives that make the electroformed gold have a velvet/satin surface? I appreciate very much if you could answer my question.
