Abstract

La invencion se refiere a un metodo para la densificacion de sustratos porosos delgados (1) por medio de infiltracion quimica de fase de vapor. El metodo inventivo involucra el uso de una herramienta de carga (19) que comprende un conducto tubular (11) el cual se coloca entre placas, primera y segunda (12, 13), y alrededor del cual los sustratos delgados por densificarse se colocan en una manera radial. Una vez cargada, la herramienta se coloca en el interior de una camara de reaccion (20) de un horno de infiltracion que tiene una entrada de gas reactiva (21) que se conecta al conducto tubular (11) con objeto de permitir que un gas reactivo entre al conducto que distribuye el gas a lo largo de la longitud de las superficies principales de los sustratos (1) en una direccion de flujo esencialmente radial. El gas reactivo tambien puede fluir en la direccion opuesta, es decir, hacia la herramienta (10) desde la envoltura externa (16) de la misma y descargarse a traves del conducto (11).
