Abstract

LO QUE SE PROPORCIONA ES UNA CERAMICA CON BASE DE NITRURO DE SILICONA QUE ES PARTICULARMENTE UTIL PARA USO COMO UNA HERRAMIENTA CORTADORA (10) EN LAS BRIZNAS A ALTA VELOCIDAD QUE SE FORMAN EN LA FABRICACION DE MATERIALES METALICOS. LA CERAMICA ESTA PREFERIBLEMENTE COMPUESTA DE AL MENOS UNA FASE DE NITRURO DE SILICONA BETA DEL 85 POR CIENTO DEL VOLUMEN (V/O) Y DE UNA FASE INTERGRANULAR MENOR QUE UNOS 5 V/O. LA CERAMICA TIENE UN PORCENTAJE DE MAGNESIO SUPERIOR AL 0,2 POR CIENTO DE SU PESO (P/O), ITRIA SUPERIOR AL 0,2 P/O, DONDE LA SUMA DEL MAGNESIO E ITRIA ES INFERIOR AL 5 P/O. LA CERAMICA TIENE POROSIDAD INFERIOR AL 0,2 V/O. LA HERRAMIENTA (10) TIENE UNA CARA INCLINADA (30) UNIDA A CARAS LATERALES (50) MEDIANTE BORDES CORTANTES (70).
