GENERATOR OF METAL-CONTAINING PLASMA Russian patent published in 1998 - IPC

FIELD: electron-ion guns, in particular, for processing of surfaces of articles. SUBSTANCE: device has cathode which is designed as spiral with ferromagnetic screen, anode which is designed as electromagnetic gun with terminals from inner and external layers. Current pulse generator is connected to terminals of spiral. Positive terminal of generator of accelerating voltage is connected to central terminal of spiral through choke. Negative pole of generator of accelerating voltage is connected to terminal of inner layer of coil. Terminal from external layer of coil is connected to terminal from external turn of spiral. Plasma generator has single chamber for ionization evaporation of metal and ionization of vapor in induction pulse discharge. EFFECT: increased protection against corrosion, increased hardness, generation of decorative surfaces, increased endurance of cutting edges. 1 dwg
