  • Gold plating with electrochemical passivation
    Patent number: 4090934
    Abstract: A process is described for making gold platings of low effective porosity. This process involves first putting down a gold layer on a surface and then passivating the surface using an electrochemical procedure. This process permits use of much thinner gold layers than ordinarily used without the danger of corrosion of underlying base metal.
