Abstract

Le procédé suivant l'invention concerne les pièces de forme fabriquées par métallurgie des poudres, qui sont densifiées par compression isostatique à chaud. Le procédé consiste à revêtir une préforme poreuse crue de deux couches de revêtement poreux. La préforme revêtue est chauffée sous vide jusqu'à une température qui provoque la densification de la couche externe qui devient étanche. On effectue alors la compression isostatique à chaud pour densifier la préforme. Le procédé permet, en particulier, de fabriquer des pièces en super-alliages à hautes caractéristiques exemptes de défauts, qui approchent de très près les dimensions désirées, ce qui réduit beaucoup les pertes de métal.
