Abstract

SE PRESENTA UN MATERIAL CERAMICO, POROSO PARA UN MIEMBRO DESLIZANTE TAL COMO UNA UNIDAD DE VALVULA O UN GRIFO DE COMBINACION. EL MATERIAL CERAMICO POROSO COMPRENDE UN CUERPO SINTERIZADO CERAMICO QUE ESTA FORMADO CON POROS UBICADOS DE FORMA DISPERSA EN EL MISMO. LOS POROS ESTA DEFINIDOS RESPECTIVAMENTE POR CAPAS SUPERFICIALES QUE FORMAN PARTE DEL CUERPO SINTERIZADO CERAMICO. CADA CAPA SUPERFICIAL CONTIENE SILICIO EN UN CONTENIDO MAYOR QUE EN LA OTRA PARTE DEL CUERPO SINTERIZADO CERAMICO. EL MATERIAL CERAMICO, POROSO, SE PREPARA, POR EJEMPLO, MEZCLANDO PRIMERO POLVO CERAMICO Y PARTICULAS HUECAS CADA UNA DE LAS CUALES CONTIENE SILICIO DE MANERA QUE SE OBTENGA UNA MEZCLA; POSTERIORMENTE SE FORMA LA MEZCLA DANDOLE UNA CONFIGURACION DETERMINADA PARA OBTENER UN CUERPO FORMADO; Y FINALMENTE SE SINTERIZA EL CUERPO FORMADO A UNA TEMPERATURA MAYOR QUE EL PUNTO DE FUSION DE CADA PARTICULA HUECA PARA OBTENER DE ESTA FORMA UN CUERPO SINTERIZADO FORMADO CON POROS Y QUE CONTIENE SILICIO.
