  • HIGH CURRENT BI-POLAR PULSE SYSTEM FOR USE IN ELECTROCHEMICAL METAL SURFACE FINISHING
    Publication number: 20190337068
    Abstract: A high current bi-polar pulse system for use in electrochemical metal surface finishing of metallic components. The high current bi-polar pulse system provides a high isolation, high current switching device for providing independently controllable, alternating polarity, variable time duration pulses for electrochemical and mechanical finishing of metallic components in a conducting fluid bath. The high current bi-polar pulse system provides a safe, low-cost solution for implementing the surface finishing of niobium (Nb) SRF accelerating cavities without the use of hydrofluoric acid.
