Abstract

The addition of sodium laurylsulfate, decylamine, and dodecylamine to the cyanide gold plating bath was found to suppress the growth of the (111) facet. Similar trends were observed for deposits obtained at higher current densities and lower temperatures. The decylamine and dodecylamine enhance the growth of (220) and (311) facets and result in lowering of the microhardness of the deposits. A shell-like morphology was obtained when the growth of (220) and (311) facets was enhanced. An increase in the concentration of sodium laurylsulfate tends to produce flake platings.
