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.METHOD OF MANUFACTURING WEAR-RESISTANT PARTS BASED ON HARD METAL. FIRST, A COMPOSITION MIXTURE IS MADE: 20 TO 70% BY WEIGHT OF STEEL POWDERS AND 30 TO 80% OF CARBIDE PARTICLES. LATER THIS MIXTURE IS PRESSED IN COLD, PRODUCING A COMPACT BODY IN A FIRST FORM OF THE PIECE. IT IS THEN PRODUCED BY SUBMITTING THE PREFORM SO OBTAINED TO A HIGH TEMPERATURE HEATING PROCESS AT THE SAME TIME THAT A DETERMINED PRESSURE IS MAINTAINED. OF APPLICATION, IN PARTICULAR, TO THE MANUFACTURE OF TOOLS.
