Abstract

PARA PREPARAR UNOS SINTETIZADOS (1) RODEADO CON UNAS CAPAS (2) DE MOLIBDENO. SE PRENSA UN POLVO DE HIERRO (10) DE BAJA ALEACION QUE FORMA EL CUERPO PRINCIPAL CON UNA CAPA DE POLVO METALICO FORMADA POR UNA MEZCLA (3) DE HIERRO NO ALEADO Y MOLIBDENO NO ALEADO QUE ORIGINA LA CAPA DE CUBIERTA (2) PARA OBTENER UNA PREFORMA (9) Y SE SINTETIZA ESTA PREFORMA PARA OBTENER EL CUERPO SINTETIZADO. PARA EVITAR LA MEZCLA DE AMBAS CAPAS DE POLVO METALICO, EL POLVO METALICO PARA LA CAPA DE CUBIERTA (2) POSTERIOR SE COMPRIME ANTES DEL ACABADO DE LA PREFORMA CON EL POLVO DE HIERRO (10) PARA EL CUERPO PRINCIPAL DE UNA PIEZA (5) PRENSADA PREVIAMENTE.
