  • Process and apparatus for preventing oxidation of metal by capactive coupling
    Patent number: 4767512
    Abstract: An effective process of preventing the oxidation of metal objects by capacitive coupling is disclosed. An electric current is impressed into the metal object by treating the metal object as the negative plate of a capacitor. This is achieved by a capacitive coupling between the metal object, a dielectric material and a positive plate. Pulses of direct current are provided to the positive plate. The metal object has a common ground with the means for providing the pulses.
