Abstract

L'invention a trait à la fabrication de pièces profilées métalliques. Elle a pour objet un procédé de fabrication de profilés métalliques à partir de particules de poudre selon lequel les particules sont façonnées en une préforme poreuse autoportante qui est soumise à une opération de pressage isostatique à chaud. Ce procédé est caracterisé par les opérations de formation d'un revêtement poreux sur la préforme avant pressage isostatique à chaud, soumission de la réforme revêtue à un vide de façon à la dégazer, chauffage de la préforme revêtue, tout en maintenant le vide, à une température suffisante pour densifier complètement ledit revêtement de sorte que celui-ci devienne non poreux et ensuite soumission de ladite préforme audit pressage isostatique à chaud Application : profiles métalliques de précision.
