Abstract

Procedimiento para la producción de componentes de acero rápido mediante la técnica de metalurgia de polvos, que comprende las etapas de: (a) compactar polvos prealeados de acero rápido atomizados por agua y revenidos; (b) nitrurar los compactos para aumentar el contenido en nitrógeno; y (c) en un mismo ciclo, sinterizar y templar en un horno de temple en verde los compactos nitrurados.Process for the production of rapid steel components by the powder metallurgy technique, which comprises the steps of: (a) compacting pre-alloyed rapid steel powders sprayed by water and tempering; (b) nitride the compacts to increase the nitrogen content; and (c) in the same cycle, sintering and tempering in a green tempering furnace the nitrided compacts.
