Abstract
UN CUERPO SINTERIZADO DE NITRURO DE SILICIO TIENE UNA COMPOSICION QUE CONSISTE ESENCIALMENTE DEL 85 AL 94% DE PESO DE NITRURO DE SILICIO , DE 6 AL 15% DE PESO DE FASE LIMITE DE GRANO QUE CONSTA ESENCIALMENTE DE (I) AL MENOS DOS ELEMENTOS DE TIERRA RARA, EN DONDE EL ITRIO ES CONSIDERADO UNA TIERRA RARA, Y, OPCIONALMENTE, EL ESTRONCIO QUE, CALCULADO COMO SRO, ES EL 0 AL 2% DE PESO DEL CUERPO TOTAL, Y (II) AL MENOS DOS DE SI, N, O Y C, Y UN ADITIVO QUE CONSISTE ESENCIALMENTE DE UN COMPONENTE DE CARBONO METAL PRESENTE EN LA CANTIDAD DE SOBRE 0.2 AL 3.5% POR VOLUMEN. EL ADITIVO ESTA SUSTANCIALMENTE DISPERSADO HOMOGENEAMENTE DENTRO DEL CUERPO SINTERIZADO. EL CUERPO SINTERIZADO TIENE UNA MICROESTRUCTURA EN DONDE (I) LOS GRANOS DE NITRURO DE SILICIO SON ACICULARES Y TIENEN UNA ANCHURA DE GRANO PROMEDIO EN LA DIMENSION DE 0.5 A 1.5 M, (II) AL MENOS EL 25% DE LOS GRANOS TIENEN LA ANCHURA MAS GRANDE QUE 0.7 M, Y AL MENOS EL 10% DE LOS GRANOS TIENEN LA ANCHURA MAS GRANDE QUE 1 M, Y (III) NO MAS QUE EL5% DE LOS GRANOS TIENEN LA ANCHURA MAS GRANDE 3.5 M Y LA PROPORCION DE ASPECTO APARENTE MAS GRANDE QUE 5, CON LA PREVISION DE QUE LA PROPORCION DE ASPECTO PROMEDIO ES AL MENOS 1.8 Y UN ORIGEN DE FRACTURA, AL MENOS EL 90% DEL CUAL ESTA COMPRENDIDO DE GRANOS SI3N4 ACICULARES MAS GRANDES, EL TAMAÑO MEDIO DE LOS CUALES SE CLASIFICA SOBRE 15 AL 50 M. TAL CERAMICA TIENE ALTA RESISTENCIA, ALTA DUREZA Y DURABILIDAD LARGO TIEMPO, Y ES ESPECIALMENTE APROPIADO PARA APLICACIONES INDUSTRIALES TALES COMO COMPONENTES PARA TURBINAS DE GAS Y MOTORES DE AUTOMOVILES
