APPARATUS FOR IONIC-PLASMA TREATMENT OF PIECES Russian patent published in 1997 - IPC

FIELD: ionic-plasma treatment of pieces. SUBSTANCE: apparatus for ionic-plasma treatment of pieces has two water cooled electrodes, one of which has cylindrical form and its one end protrudes through insulated inlet out of vacuum chamber; quenching device located around cylindrical electrode in side of insulated inlet; firing device located at opposite end of cylindrical electrode; vacuum arc source of power. Apparatus has high-voltage and low-voltage direct current sources of power, switch and system of bleeding-in. Second electrode is made in the form of spiral surrounding cylindrical electrode and coaxial to it and its end located on side of quenching device is connected to positive terminal of vacuum arc power source and to negative terminal of high-voltage source of power and its both ends are connected to low-voltage source of power. Cylindrical electrode through switch is connected to negative terminal of vacuum arc source of power and to positive terminal of high-voltage source of power. Negative terminal of high-voltage source of power is grounded through resistor. EFFECT: improved design. 1 dwg
