Abstract

PROCEDE DE FABRICATION D'UNE POUDRE A BASE DE FER CONTENANT DU CUIVRE DESTINEE A LA METALLURGIE DES POUDRES. CETTE POUDRE A BASE DE FER ALLIE PAR DIFFUSION AVEC DU CUIVRE EST MELANGEE AVEC DE LA POUDRE DE FER PUR EN UNE QUANTITE SUFFISANTE POUR AVOIR LA TENEUR EN CUIVRE CHERCHEE ET ADDITIONNEE DE PHOSPHORE SOUS FORME DE FERROPHOSPHORE POUR AVOIR UNE TENEUR EN PHOSPHORE DE LA POUDRE DE FER JUSQU'A 1,5 EN POIDS, DE PREFERENCE DE 0,15 A 1 EN POIDS. UTILISATION DE CETTE POUDRE POUR FABRIQUER DES PIECES EN GRANDE SERIE PAR LA METALLURGIE DES POUDRES, AYANT UNE GRANDE PRECISION, UNE STABILITE DIMENSIONNELLE ET UNE RESISTANCE ELEVEES.
