Abstract
A cathode, particularly a lead cathode, which is immune to plating zinc on its surface when used in an electrolytic galvanizing solution. The method of producing such a cathode which comprises placing the lead cathode in an electrolytic solution containing zinc ions, electrolytically forming a light zinc coating on the surface of the cathode, and removing the zinc coating from the surface of the cathode, preferably by interrupting the applied current for a sufficient period to permit the zinc coating to dissolve in the electrolytic solution.
