Abstract
An improved process is described for the electrodeposition of both a low overvoltage metal and a sacrificial metal onto an electrically conductive substrate. The sacrificial metal is later removed by leaching the electroplated substrate with sodium hydroxide. The improvement comprises adding a sacrificial metal to the electroplating solution after electrodeposition is initiated. The amount of electric current supplied to the electroplating solution during electrodeposition may be increased or decreased to increase the surface area and the electrochemical activity of the electroplated substrate.
