Abstract

Nouveau procédé d'élimination du métal d'un corps autoporteur formé. On produit un corps autoporteur par infiltration réactive d'un métal de base fondu dans un lit ou dans une masse contenant une matière donneuse de bore ainsi qu'une matière donneuse de carbone (par exemple, du carbure de bore) et/ou une matière donneuse de bore et une matière donneuse d'azote (par exemple, du nitrure de bore) et, facultativement, une ou plusieurs matières de remplissage inertes. Une fois le corps autoporteur formé, on le soumet à des conditions appropriées provoquant l'élimination au moins partielle de constituants métalliques contenus dans ledit corps autoporteur.
