Abstract

On produit cette poudre de particules secondaires (1), d'un diamètre particulaire compris entre 10 et 500 νm, en liant les unes aux autres les particules d'une poudre de particules élémentaires (2) essentiellement constituée d'aluminium et d'un diamètre particulaire compris entre 5 et 300 νm et ce, à l'aide d'un liant organique (3). On produit, de la même façon, une autre poudre de particules secondaires d'un diamètre particulaire compris entre 50 et 200 νm en liant les unes aux autres les particules d'une poudre de particules élémentaires essentiellement constituée de fer et d'un diamètre particulaire compris entre 20 et 100 νm et ce, à l'aide d'un liant organique. Ce procédé est employé pour produire un alliage en poudre d'une fluidité remarquable et l'on utilise la poudre de particulaires secondaires résultante pour produire un alliage en pastilles frittées des mieux calibrées.
