METHOD AND DEVICE FOR ELECTRIC SPARK DEPOSITION OF COATS Russian patent published in 1998 - IPC

FIELD: deposition of coats. SUBSTANCE: method is realized under conditions of periodic contact of electrodes with excitation of spark discharges between them. In this case working electrode is imparted with rotary motion composed of discrete movements which frequency of following is synchronized with that of excitation of spark discharges emerging in pauses between movements of electrodes. Device for implementation of method includes doping electrodes connected through brush contacts to source of pulses of electric currents and elastically anchored on one of ends of axis coupled to actuating motor to give electrodes. rotary motion. Actuating motor is stepping one for synchronization of discrete turns of electrodes with pulse repetition frequency of electric current. EFFECT: high-quality and high-productivity deposition of coats, 3-5 times increased service life of coats. 2 cl, 2 dwg
