Abstract

Procedimiento para la fabricación de cuerpos metálicos resistentes al desgaste y duros que comprende mezclar polvo metálico y un agente de boruración en forma de polvo, disponer la mezcla en un molde, y consolidarla, así como sinterizar el cuerpo así formado a temperaturas de 700 a 1.300ºC bajo una atmósfera protectora, caracterizado por utilizar boro y/o carburo de boro y/o boruro de titanio como agente de buroración en una cantidad hasta de 25% en peso del polvo metálico, y consolidar la mezcla a una densidad de al menos 80% del valor teórico.
