DEVICE FOR PLASMA-DETONATION SPRAYING OF COATINGS Russian patent published in 1994 - IPC

FIELD: mechanical engineering, coating application technologies. SUBSTANCE: device has electrode secured axially with detonation device and provided with through axial channel containing current-conducting nozzle connected as an anode into electrical circuit of the source of power. The walls of the combustion chamber, in the place of location of the end of the electrode, are provided with one or more holes carrying the current-conducting nozzles connecting as cathodes in the electrical circuit. At their ends the nozzles are provided with devices for constant-speed feeding of wire or bars. EFFECT: extended operating capabilities due to possibility of concurrent use or bar- or wire-type materials. 1 dwg
