Abstract

UN METAL CUERPO DE CARBURO CEMENTADO DURO, RELATIVAMENTE NO FRAGIL, SE OBTIENE POR SINTERIZACION DE POLVOS DE CARBUROS DE GRADO PRENSADOS EN PRESENCIA DE UN MATERIAL CONTENIENDO BORO TAL COMO NITRURO DE BORO. DURANTE LA SINTERIZACION, CANTIDADES APRECIABLES DE BORO MIGRANO SE DIFUNDEN AL CUERPO LLEGANDO A SER INCORPORADAS A LA MICROESTRUCTURA DEL CARBURO RESULTANDO EN LA FORMACION DE UNA TERCERA FASE CUATERNARIA QUE CONTIENE WF, CO, B Y C.
