Abstract

La présente invention concerne une installation d'injection de gaz froid (10) comprenant un dispositif de chauffage de gaz (90) et une chambre de stagnation (60) connectée au dispositif de chauffage de gaz (90). Une tuyère de Laval (20) est connectée à la chambre de stagnation, laquelle tuyère libère côté sortie un courant de gaz dans lequel se trouvent des particules (T) à une vitesse supersonique. Des installations d'injection de gaz froid de ce type peuvent par exemple être utilisées pour appliquer un revêtement sur une surface avec les particules accélérées. L'objectif de l'invention est d'obtenir une qualité de revêtement encore meilleure lors de la fabrication d'un revêtement. A cette fin, au moins une partie de l'installation d'injection de gaz froid située derrière le dispositif de chauffage de gaz lorsqu'elle est observée dans la direction d'écoulement du gaz est dotée d'une protection thermique en ce qu'elle est revêtue côté paroi intérieure d'un matériau isolant en céramique présentant une conductivité thermique inférieure à 20 W/Km ou en ce qu'elle est composée d'un tel matériau. Le revêtement peut par exemple être assuré par un élément rapporté échangeable (110, 140) qui sépare du courant de gaz la paroi intérieure de ladite partie. Un tel élément rapporté peut par exemple présenter un manchon partiellement cylindrique et partiellement conique, notamment tronconique, dont la partie cylindrique est insérée dans la chambre de stagnation et dont la partie conique est insérée dans la partie convergente de la tuyère de Laval.
