Abstract

La invencion se refiere a un procedimiento para formar un artículo sinterizado de metal en polvo, que comprende mezclar grafito y lubricante con un polvo a base de hierro de aleacion previa, prensar la mezcla para formar en una sola etapa de compactacion, sinterizar al artículo, y luego a temperatura elevada sinterizar el artículo en una atmosfera reductora para producir un artículo sinterizado de una densidad mayor de 7-4 g/cc.
