Abstract

Un procédé de fabrication d'une aube (1) creuse de turbomachine comporte après le soudage-diffusion des pièces constitutives (2,3,4) une étape complémentaire réalisant le décollement des zones enduites d'un revêtement d'anti-diffusion au cours de laquelle un conduit d'alimentation en gaz (90) est formé dans une zone de l'aube où des trous (5) sont ménagés dans la tôle intermédiaire (4), au moyen d'injections contrôlées de gaz sous pression tout en assurant un chauffage localisé de ladite zone de l'aube. Un dispositif particulier est prévu pour la réalisation de l'opération.
