RAIL PLASMA GENERATOR TO MANUFACTURE COATS ON SURFACES OF DIELECTRIC MATERIALS Russian patent published in 1998 - IPC

FIELD: coating of dielectric materials. SUBSTANCE: rail plasma generator to manufacture coats on surfaces of dielectric materials has two electrodes ( anode and cathode ) placed in parallel with reference to each other, magnetic system to create homogeneous magnetic field between electrodes along entire length, aids to ignite and extinguish arc discharge and current leads. Aids o ignite and extinguish arc discharge are installed on opposite ends of electrodes and are coupled to aid inserted to synchronize their operation. Cathode has through capillary conduits and is fitted with vessel for evaporated material. Electrodes are located in air gap of magnetic system that is made in the form of 2N permanent magnets of rectangular section provided with common magnetic core, magnetized in axial direction and uniaxially arranged in pairs at same distance between unlike poles on both sides of plane of location of electrodes and at same acute angle with respect to its positive normal. Symmetry axes of N pairs of permanent magnets are located in parallel planes distance between which equals proper dimension of permanent magnets. In this case angle β included between positive normal to surface of positioning of electrodes and vector of induction of magnetic field in air gap of magnetic system satisfies relation 180^°< β > 225^°, and component of vector of induction of magnetic field is directed towards ignition of arc discharge. EFFECT: expanded application field and simplified design of plasma generator. 5 dwg
