Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE PARTES SINTERIZADAS CON ALTA RESISTENCIA AL DESGASTE Y BUENAS PROPIEDADES DE RESISTENCIA DINAMICA A BASE DE CUERPOS MOLDEADOS, QUE HAN SIDO PRESIONADOS COMO PRODUCTOS BASICOS A PARTIR DE POLVO DE ACERO DE MEJORA DE ALEACION ELABORADA CON CAPACIDAD DE ENDURECIMIENTO CON AIRE CON UN CONTENIDO EN CARBONO ADICIONADO EN FORMA DE GRAFITO DE AL MENOS 0,3 %, MEDIANTE SINTERIZADO BAJO GAS DE PROTECCION EN UNA TEMPERATURA DE SINTERIZADO DE AL MENOS 1.000 INUACION. CON ELLO SE REFRIGERAN LAS PARTES SINTERIZADAS DE FORMA INMEDIATA EN CONEXION CON LA SINTERIZACION DE TEMPERATURA SOBRE UNA TEMPERATURA DE MANTENIMIENTO EN LA ZONA DE AR{SUB,3} COMO MAXIMO DE 150 RANTE UN PRIMER TIEMPO DE MANTENIMIENTO DE 5 -25 MIN A ESTA TEMPERATURA (FASE DE AUSTENIZACION), IMPULSANDOSE A CONTINUACION DE FORMA INMEDIATA LAS PARTES SINTERIZADAS MEDIANTE ENFRIAMIENTO DE GAS CONVECTIVO HASTA UNA SEGUNDA TEMPERATURA DE MANTENIMIENTO Y SIENDO MANTENIDA DURANTE UNSEGUNDO TIEMPO EN ESTA TEMPERATURA, DONDE LA SEGUNDA TEMPERATURA DE MANTENIMIENTO SE ENCUENTRA EN UNA ZONA DE TEMPERATURA, EN LA QUE SE CONFIGURA UNA ESTRUCTURA DE VAINITA, Y EL SEGUNDO TIEMPO DE MANTENIMIENTO SE DIMENSIONA DE TAL MODO, QUE SE AJUSTA UNA PORCION DE ESTRUCTURA DE VAINITA DE AL MENOS 50 %, Y LAS PARTES SINTERIZADAS SE REFRIGERAN A CONTINUACION HASTA LA TEMPERATURA AMBIENTE. LA INVENCION SE REFIERE ADEMAS A UN DISPOSITIVO CORRESPONDIENTE.
