Abstract

SE PRESENTA UN MATERIAL DE COMPOSICION CERAMICA MEJORADO BASADO EN CIRCONIO Y NITRURO DE BORO QUE SE PUEDE LIGAR SATISFACTORIAMENTE SIN SINTERIZACION. EL MATERIAL COMPRENDE UNA MEZCLA PARTICULADA DE NITRURO DE BORO, CIRCONIO ESTABILIZADO Y NITRURO DE SILICONA LIGADOS MEDIANTE BATIDOS DE NITRURO DE SILICONA. LOS BATIDOS DE NITRURO DE SILICONA SE PUEDEN FORMAR CONVENIENTEMENTE IN SITU CALENTANDO LA MEZCLA DE NITRURO DE BORO, CIRCONIO ESTABILIZADO Y NITRURO DE SILICONA JUNTA CON SILICONA METALICA EN POLVO EN UNA ATMOSFERA DE NITROGENO.
