ELECTRIC-ARC PLASMATRON Russian patent published in 2006 - IPC H05H1/26 C23C4/00 

FIELD: material treatment in metallurgy, plasma chemistry, and mechanical engineering.

SUBSTANCE: proposed electric-arc plasmatron that can be used for coating materials, producing heavy parts and blanks, treatment of dispersed materials and aerosols, and plasmo-chemical fusion has cathode unit with cathode, insulator, anode unit with nozzle anode, plasma-generating gas inlet system, and system for introducing material under treatment, all being cooled down and coaxially arranged in tandem providing their focusing in near-cathode region. The latter turns to cylindrical region of nozzle anode. Anode unit has transport systems for process and shielding materials. Transport systems have their outlet to butt-end of anode unit through annular channels at angles ω₁ and ω₂ to longitudinal axis of plasmatron. Angles ω₁ and ω₂ dictate kind of interaction between process and shielding materials and plasma jet. Process and shielding materials are introduced in plasma jet in the form of liquid, aerosol, suspension, gas, powder, or their combination.

EFFECT: enlarged functional capabilities of plasmatron.
