DEVICE FOR IONIC-PLASMA SPRAYING OF MATERIALS IN VACUUM Russian patent published in 1997 - IPC

FIELD: devices for ionic-plasma spraying of materials in vacuum. SUBSTANCE: device for ionic-plasma spraying of materials in vacuum is a perfected design in which pole pieces are made to form gaps embracing each other. Installed in embraced gap is cathode - target, and in embraced gap, anode is installed. Pole pieces may be made with alternating gaps. EFFECT: higher degree of ionization of working gas in zone of spraying due to formation of directed ionic flow of working gas from layer adjacent to anode, where, in the gap between pole pieces, electric and magnetic fields are crossed. 2 cl, 1 dwg
