A method for manufacturing a brazed part is disclosed that includes coating a substrate surface to be joined by first cold spraying a braze filler metal powder upon the surface to clean the surface followed by further spray the powder to form a coating layer of a braze alloy upon the surface. The coated surface is assembled with another surface to be joined and brazed together to form the brazed part. The substrate and braze alloy may be nickel-based super alloy materials.
L'invention concerne un procédé de fabrication d'une partie brasée comprenant le revêtement d'une surface d'un substrat à associer en pulvérisant à froid, dans un premier temps, une poudre métallique de charge pour brasage sur la surface afin de la nettoyer, puis en pulvérisant à nouveau la poudre pour former une couche de revêtement composé d'un alliage de brasage sur la surface. La surface revêtue est assemblée avec une autre surface à associer et elles sont toutes deux brasées pour former la partie brasée. Le substrat et l'alliage de brasage peuvent être des matériaux de type superalliage à base de nickel.
