Optimization study on hardness of gold film through supercritical electroplating process by response surface methodology [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2015 A non-cyanide gold bath has been used to deposit gold film on a brass substrate through electroplating process using supercritical carbon dioxide emulsion. The hardness of deposited gold film was considered as a response variable to optimize the

Gold electroplated spectacle frames [PDF]
Gold Bulletin, 1979 Electrocoating of spectacle frames is one of the more traditional uses of gold and its alloys and may tend to be regarded as a simple and straightforward process. In this review, the authors show that, in fact, careful control and monitoring of manufacturing conditions and quality are essential to obtain a satisfactory product.
