Abstract

PROCEDIMIENTO PARA UNIR ENTRE SI DOS O MAS ELEMENTOS METALICOS EN POLVO. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE FORMA UN PRIMER ELEMENTO (12) METALICO EN POLVO A BASE DE HIERRO, QUE TENGA LA CONFIGURACION DESEADA Y QUE CONTENGA ADEMAS DEL HIERRO UNA CANTIDAD SUFICIENTE DE COBRE PARA PRODUCIR SU EXPANSION TRAS EL SINTERIZADO; SEGUNDA, SE FORMA UN SEGUNDO ELEMENTO (10) METALICO EN POLVO A BASE DE HIERRO, EN UNA CONFIGURACION TAL QUE SE PUEDA ACOPLAR CON EL PRIMER ELEMENTO (12) FORMADO, ESTANDO COMPUESTO ADEMAS DE HIERRO DE UNA CANTIDAD SUFICIENTE DE NIQUEL PARA PRODUCIR SU CONTRACCION TRAS EL SINTERIZADO; TERCERO, SE ACOPLAN EL PRIMER Y EL SEGUNDO ELEMENTO (12 ,10) METALICOS DE MANERA ADECUADA PARA PODER SOMETERLOS AL TRATAMIENTO DE SINTERIZACION; Y POR ULTIMO, SE CALIENTAN DICHOS ELEMENTOS A UNA TEMPERATURA DE SINTERIZACION SUFICIENTE PARA CAUSAR LA UNION METALURGICA DE DICHOS ELEMENTOS ENTRE SI.
