ELECTRIC ARC SPRAYING DEVICE Russian patent published in 2014 - IPC C23C4/12 

FIELD: electricity.

SUBSTANCE: in electric arc spraying device there are two electrodes and two nozzles installed at convergence angle from 30 up to 45°, the electrodes are located inside nozzles, their axes coincide with axes of the nozzles where they are installed, at that square areas of free annular section of the nozzles, through which gas is supplied, are identical and equal from 10 up to 30 mm², and length of the nozzle channels forming gas flows is not less than 1.5-2.0 times than their diameter.

EFFECT: increasing use efficiency for the sprayed material, adhesion and porosity of the sprayed coatings due to receipt of a more compact metalized flow and speed for particles of the sprayed metals.
