Abstract
Un procedimiento para la fabricación de un artículo metálico sinterizado que incluye las etapas de prensar un polvo metálico a una densidad de al menos 88,5% de la densidad teórica para formar una briqueta, sinterizar la briqueta, mecanizar finamente la superficie del artículo sinterizado (como se define en esta memoria), y someter a nitrocarburación el artículo mecanizado para proporcionar una capa superficial ("capa blanca") en una profundidad desde la superficie del artículo que no excede de aproximadamente 250 micras.
