Abstract

L'invention concerne un procédé de fabrication de poudre métallique. Le procédé est caractérisé en ce qu'on met sous vide une chambre dans laquelle le processus se déroule jusqu'à une pression de 0,5 bar (0,05 MPa) ou en dessous et en ce qu'on maintient la pression à ce niveau pendant le processus d'atomisation en poursuivant la mise sous vide de façon à réduire sensiblement l'emprisonnement du gaz dans la poudre. Application à la fabrication de poudres de super-alliages à base de nickel, de fer ou de cobalt.
