  • Patent number: 5575900
    Abstract: Opportunistic decorative mass production gold plating solutions are described which are capable of plating gold at concentrations as low as one-half pennyweight per gallon based on an alkaline gold cyanide complex. The low concentration enables ecological operations as well as low working capital inventory operations. The solutions feature high efficiency "put through" replenishment of gold, and non 24 Karat gold deposition capabilities such as 18 and 14 Karats without the necessity of adding metal salts. The solutions operate over a pH range of one to seven without affecting the stability of the gold cyanide complex in the pH range of 1-2.5. A preferred embodiment of the invention comprises an electrolyte mixture of three buffer salts and two chelating agents capable of depositing bright hard 18 Karat gold colored deposits.
