Abstract

L’invention concerne un procédé de fabrication par compression isostatique à chaud d’une pièce outil (10) formée par au moins une partie utile (1) et au moins une partie support (21, 22, 23, 24) scellées entre elles, le procédé comprenant les étapes suivantes :a) assembler l’au moins une partie utile (1) avec l’au moins une partie support (21, 22, 23, 24) ;b) fournir un conteneur pourvu d’un réceptacle et d’un couvercle ;c) placer l’assemblage formé lors de l’étape a) dans le réceptacle et positionner le couvercle sur le réceptacle de manière à fermer de manière hermétique le conteneur ;d) soumettre le conteneur fermé de manière hermétique à un traitement thermique, et à un environnement d’une pression comprise entre 500 bar et 2000 bar, de manière à sceller les parties utile et support entre elles. Figure pour l’abrégé : figure 12.
