Abstract

La présente invention concerne un dispositif et un procédé de pulvérisation plasmatique. Le dispositif comprend une cathode, une anode, un canal plasmatique formé par l'anode et des électrodes intermédiaires, et un ou plusieurs injecteurs de matériaux fluidifiables. Ledit canal comprend une partie d'étranglement qui le divise en une partie haute pression près de la cathode formée par au moins une électrode intermédiaire et une partie basse pression près de l'anode. Lors du fonctionnement, un gaz générateur de plasma est chauffé par l'arc maintenu entre la cathode et l'anode, formant le plasma. Lorsque le plasma passe par la partie d'étranglement, sa vitesse augmente jusqu'à une vitesse supersonique, et en même temps sa pression statique chute. Des matériaux fluidifiables sont injectés dans le flux de plasma dans la partie basse pression. Les particules des matériaux fluidifiables sont chauffées par le plasma et les particules chauffées résultantes et le plasma sont émis par l'orifice de sortie dudit canal.
