Abstract

L'invention concerne un procédé de solidarisation de pièces en acier inoxydable ou en superalliage par brasage diffusion. Selon l'invention, une couche d'un matériau d'interface est interposée entre les pièces à assembler. Le matériau d'interface est choisi dans un groupe comprenant l'étain, l'indium, l'antimoine, le germanium ou le gallium ou est formé d'une combinaison de ces éléments. Le traitement thermique est effectué dans tous les cas à une température supérieure à 900 degrés C. L'invention s'applique à l'assemblage de pièces en acier inoxydable ou en superalliage et plus particulièrement à la fixation de pistes abradables sur leur support.
