Abstract

La présente invention concerne un mélange de poudre pour la métallurgie des poudres qui est extrêmement fluide, qui peut être retiré d'une matrice de moule de compactage de poudre avec une faible force, et qui supprime l'usure du moule pendant le moulage. Le mélange de poudre pour métallurgie des poudres contient une poudre de matière première, un liant et une poudre de graphite, la poudre de matière première contenant au moins 90 % en masse d'une poudre à base de fer par rapport à la poudre de matière première, la poudre de graphite ayant une taille de grain moyenne inférieure à 5 µm, le rapport [mb/(mr + mg) × 100] de la masse du liant (mb) au total de la masse de la poudre de matière première (mr) et de la masse de la poudre de graphite(mg) étant de 0,10 à 0,80 % en masse, le rapport [mg/(mr + mg) × 100] de la masse de la poudre de graphite (mg) au total de la masse de la poudre de matière première (mr) et de la masse de la poudre de graphite (mg) étant de 0,6 à 1,0 % en masse, la surface de la poudre de matière première étant au moins partiellement revêtue avec le liant, et la surface du liant recouvrant la surface de la poudre de matière première étant au moins partiellement revêtue avec la poudre de graphite.
