Abstract

L'invention concerne un procédé permettant d'enduire (12) de particules abrasives (14) des pointes d'aube de compresseur ou de turbine (160, 254) d'un disque aubagé. Ledit procédé comprend les étapes consistant à : installer (60) les aubes (150, 252) sur un disque (146, 246), et ensuite appliquer par pulvérisation gazodynamique à froid (66) les particules abrasives (14) sur les pointes d'aube (160, 254), tandis que les aubes (150, 252) sont installées sur le disque (146, 246). Selon un autre mode de réalisation, un procédé permettant d'enduire de particules abrasives (14) des pointes d'aube de compresseur ou de turbine (160, 254) d'une roue aubagée consiste à poncer les pointes d'aube (160, 254) pour donner à la roue aubagée un diamètre prédéterminé. Ensuite, les surfaces de la roue aubagée ne nécessitant pas d'enduction sont masquées. Après avoir masqué la surface ne devant pas être enduite, les particules abrasives (14) sont déposées par pulvérisation gazodynamique à froid sur les pointes d'aube (160, 254). Pour les deux modes de réalisation, une couche résistante à l'oxydation est susceptible d'être déposée par pulvérisation gazodynamique à froid sur les pointes d'aube (160, 254) avant de pulvériser les particules abrasives (14).
