Abstract

SE PROPORCIONA UN FILTRO (10) QUE COMPRENDE UNA PRIMERA CAPA DEL FILTRO (12) HECHA DE PARTICULAS DE TI{SUB,4}O{SUB,2} O TI{SUB,4}O{SUB,7} DEPOSITADAS EN UNA SEGUNDA CAPA DEL FILTRO (14) POR UNAS PARTICULAS DE ACERO INOXIDABLE. LA PRIMERA CAPA (12) TIENE UN TAMAÑO DE LOS POROS MAS PEQUEÑO QUE LA SEGUNDA CAPA (14). LA CONSTRUCCION DEL FILTRO (10), EL GROSOR RELATIVO DE LAS CAPAS (12, 14) Y SU RESISTENCIA AL MOVIMIENTO ENTRE LAS MISMAS DEL GAS GENERADO ELOCTROLITICAMENTE LOCALIZADO ENTRE LAS DOS CAPAS (12, 14) CUANDO EL FILTRO (10) ES PERMEADO CON UN LIQUIDO SON TAL QUE EL GAS LLEGA A LA CARA SUPERIOR DEL FILTRO ANTES QUE A LA CARA INFERIOR. DE ESTA FORMA, EN UN MODELO, LAS PARTICULAS DE ACERO INOXIDABLE SON SINTERIZADAS Y LAMINADAS CON UN LAMINADOR TEXTURADO ANTES DE QUE LAS PARTICULAS DE CERAMICA SEAN APLICADAS Y LAMINADAS. SE PROPORCIONA UNA CAPA INTERMEDIA DE PICOS Y CERAMICAS DE PARTICULAS METALICAS RELLENAS LA CUAL TIENE UNA TORTUOSIDAD ALTA. LA RESISTENCIA A LA CORRIENTE EN LA INTERFAZCERAMICA/METAL PUEDE SER AUMENTADA POR ELECTRODEPOSICION DE METAL EN ESTE LUGAR.
