Abstract

PROCEDIMIENTO PARA LA FABRICACION POLVOMETALURGICO DE UNA PIEZA, LLENANDO UN MOLDE CON UN POLVO METALICO O CERAMICO, SECO Y SIN AGLOMERANTES NI DISOLVENTES. SE COMPACTA GOLPEANDO Y SE SINTERIZA PREVIAMENTE, SIN CONTRACCION SIGNIFICANTE, AL 0,65 HASTA EL 0,85 DE LA TEMPERATURA DE FUNDICION ABSOLUTA DURANTE 1/2 A 1 H. PARTICULAS DE POLVO VECINAS SOLAMENTE LIGAN EN SUS PUNTOS DE CONTACTO POR UNION DE CUELLO A FORMAR UNA PIEZA MOLDEADA EN BRUTA. ESTA PIEZA EN BRUTA SE SACA DEL MOLDE Y SE SINTERIZA A UNA TEMPERATURA DE POR LO MENOS 0,9 DE LA TEMPERATURA DE FUNDICION ABSOLUTA, DURANTE 1 H, SIN APOYO ADICIONAL POR UN MOLDE. PREFERENTEMENTE SE PRENSA EL CUERPO SINTERIZADO DE FORMA CALIENTE ISOSTATICA, SIN MOLDE, PARA ALCANZAR POR LO MENOS EL 98 % DE LA DENSIDAD TEORICA.
