<p>Characteristics of soft gold plating produced by electrolysis are improved by adding trace amounts of lead to the gold plating solution and by replenishing such content during use. Such characteristics include improved brightness and uniformity of deposits, better defined crystallinity of deposits, enlarged current density range, and extended solution life. Lead content generally less than about 1 ppm, based on the solution, does not affect purity of gold deposit as measured by ordinary analytical techniques.</p> |
