  • Nonplating cathode and method for producing same
    Patent number: 4234406
    Abstract: A lead cathode which is immune to plating zinc on its surface when used in an electrolytic galvanizing solution.
    Type: Grant
    Filed: April 5, 1979
    Date of Patent: November 18, 1980
    Assignee: National Steel Corporation
    Inventors: Richard A. Bird, Lowell W. Austin
  • Nonplating cathode and method for producing same
    Patent number: 4160703
    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.
    Type: Grant
