Abstract

L'invention concerne un procédé et un système de pulvérisation thermique comprenant un générateur de gaz chaud ayant une buse accélérant un gaz chauffé vers un substrat sous la forme d'une colonne de gaz faisant saillie sur la surface du substrat sous la forme d'un point. Un ou plusieurs injecteurs de charge d'alimentation à proximité de la sortie de la buse, dirigés vers la colonne de gaz, sont reliés à une source de charge d'alimentation. Le flux de gaz chaud transfère la chaleur et le moment à la charge d'alimentation, amenant les particules de charge d'alimentation à venir frapper le substrat pour former un revêtement. Le système comprend en outre un ou plusieurs injecteurs de liquide à proximité de la sortie de la buse, dirigés vers l'axe et reliés à une source de liquide. Le système commande le flux et la vitesse avec lesquels est injecté le liquide, permettant le contrôle de la profondeur de pénétration du liquide dans la colonne de gaz. Le procédé empêche sélectivement que des particules de charge d'alimentation non optimales adhèrent au substrat et permet l'élimination sur place de dépôts non optimaux.
