Abstract
An apparatus and process for depositing metal from one conductor to another by electrode deposition. One conductor, the electrode, may remain in contact with the other conductor, the workpiece, as the electrode is continuously oscillated about a central electrode axis. Short duration, high amperage charges are directed through the oscillating electrode and the workpiece. The charge duration is controlled by the charging rate of a capacitor in a charging circuit. The rate of capacitor discharge is prescribed by an independently triggered thyristor. Extremely short duration discharges at a high discharge frequency results in deposition of the electrode material onto the workpiece.
