Abstract

L'invention concerne une préforme (28) coulée en barbotine ou comprimée à partir d'un composé métallique ou d'un mélange de composés métalliques, frittée à l'air libre, sous vide ou dans un gaz inerte, et qui est réduite par voie électrolytique dans un bain (20) de sel fondu afin de former un métal poreux ou un produit à alliage. Cet alliage se présente sous forme d'éponge poreuse solide. Dans le bain (20), le sel est en contact avec un réservoir (26) de matériau d'infiltration fondu (24). Une fois la réduction électrolytique terminée, le produit poreux est déplacé dans le matériau d'infiltration qui en remplit les pores, ce qui déplace le sel. Le produit infiltré est ensuite solidifié en vue d'autres traitements des matériaux.
