Abstract

LOS OBJETOS A LOS QUE SE REFIERE LA INVENCION SON HERRAMIENTAS CUYA CONFIGURACION SEA CON Y SIN ARRANQUE DE VIRUTAS. SEGUN LA INVENCION EN LAS SUSTANCIAS ENDURECIDAS DE CARBONITRURO DE LA FORMULA GENERAL (M SUB QM ELEVADO *1(C SUB 1-YN SUB Y) SUB 2, LA COMPOSICION SUMARIA SE ENCUENTRA EN LOS LIMITES 0,5 (MENOR O IGUAL) Q (MENOR O IGUAL) 0,97, 0,03 (MENOR O IGUAL) P (MENOR O IGUAL) 0,5, 0,80 (MENOR O IGUAL) P + Q (MENOR O IGUAL) 1 Y 0,05 (MENOR O IGUAL) Y (MENOR O IGUAL) 0,95 EN ESTEQUIMETRIA TOTAL DE Z (MAYOR O IGUAL) 0,90. LOS CARBONITRUROS CONSTAN DE AL MENOS DOS FASES DISTRIBUIDAS SOBRE PARTICULAS DE POLVO SEPARADAS, Y EL EQUILIBRIO TERMODINAMICO ESTA AJUSTADO EN RELACION A LOS NO METALES CARBONO (C) Y NITROGENO (N) PERO NO PARA TODO EL SISTEMA. SEGUN LA INVENCION SE FABRICARAN, ENTRE OTRAS, LAS SUSTANCIAS ENDURECIDAS DE CARBONITRURO, EN LA MEDIDA EN QUE EN UN ESPACIO DE TIEMPO SUFICIENTEMENTE CORTO SE CALIENTA LA DEBIDA MEZCLA DE POLVO, BAJO UNA MEZCLA GASEOSA CORRIENTE DE NITROGENO/HIDROGENO Y/O GAS INERTE CON RELACIONES DE PRESION PARCIAL DEL NITROGENO RESPECTO AL HIDROGENO Y/O GAS INERTE DE 1 : 0,5 A 1 : 5 A TEMPERATURAS DE 1.800 C A 2.000 C. LA SUSTANCIA DE CARBONITRURO SEGUN LA INVENCION PUEDE SER EMPLEADA, ENTRE OTROS, COMO COMPONENTE DE UN CERAMAL O DE UNA CAPA QUE INHIBA EL DESGASTE.
