Abstract

METODO DE FABRICACION DE PIEZAS RESISTENTES AL DESGASTE A BASE DE METAL DURO. PRIMERAMENTE SE HACE UNA MEZCLA DE COMPOSICION: 20 A 70% EN PESO DE POLVOS DE ACERO Y 30 A 80% DE PARTICULAS DE CARBUROS. POSTERIORMENTE SE PRENSA DICHA MEZCLA EN FRIO, PRODUCIENDO UN CUERPO COMPACTO EN UNA PRIMERA FORMA DE LA PIEZA. A CONTINUACION SE PRODUCE A SOMETER LA PREFORMA ASI OBTENIDA A UN PROCESO DE CALENTAMIENTO A ALTA TEMPERATURA AL MISMO TIEMPO QUE SE MANTIENE UNA PRESION DETERMINADA. DE APLICACION, EN PARTICULAR, A LA FABRICACION DE HERRAMIENTAS.
