Abstract

L'invention concerne un plasmatron qui comprend une électrode (1) et une buse (2) munie d'un canal (3) servant à acheminer un gaz supplémentaire vers un jet de plasma. L'intérieur du canal (3) est muni d'un canal (4) servant à acheminer une poudre vers le jet de plasma. Les parois des canaux (3, 4) sont contiguës à leur sortie au point (5) le plus proche de l'électrode (1). Le gaz supplémentaire empêche la poudre de se déposer sur les parois de la buse (2) même lorsque le gaz supplémentaire et le gaz servant au transport de la poudre circulent à un débit faible.
