APPARATUS FOR ELECTRIC SPARK STRENGTHENING Russian patent published in 2001 - IPC

Abstract RU 2171162 C2

FIELD: electrophysical and electrochemical treatment processes. SUBSTANCE: apparatus includes tool-electrode, direct electric current source and transformer. Secondary winding of transformer is connected with tool-electrode and treated part. Inlet of pulse generator is connected with direct current source; its outlet is connected with thyristor. The last is connected in series with primary winding of transformer, being high voltage transformer. EFFECT: enhanced efficiency of process due to high frequency of electric spark discharges in such apparatus. 1 dwg
