Electrolysis Apparatus and a Method of Hydrodynamic Cavitation Protection.

摘要

The patent application discloses a method and apparatus for protecting the surfaces of hydrodynamic members subjected to a cavitating fluid environment such as seawater. A conductive metal insert is affixed to and electrically insulated from the surface of the member where cavitation damage is most likely ot occur. A variable d-c voltage is connected between the metal insert (cathode) and the hydrodynamic member (anode). As the voltage is applied, a protective layer of hydrogen gas bubbles is formed over the conductive metal insert to thereby cushion the shock of the collapse of the cavitation voids.
