Abstract

ESTE MATERIAL COMPUESTO METALICO/CERAMICO SE COMPONE DE UNA CUBIERTA SUPERFICIAL CERAMICA FORMADA POR UNA ALEACION OXIDADA DE COBRE ESTABILIZADA A TRAVES DE LA FORMACION DE UNA SOLUCION SOLIDA CON OXIDO DE NIQUEL O MANGANESO EN UN SUSTRATO QUE ES UNA ALEACION RESISTENTE A LA OXIDACION, COMPUESTA ESENCIALMENTE POR COBRE O CUALQUIER OTRO METAL QUE SE OXIDE MAS FACILMENTE QUE EL COBRE. EL COMPUESTO SE PREPARA POR LA OXIDACION DE LA ALEACION DE COBRE Y DEL SUSTRATO SIMULTANEAMENTE, DE FORMA QUE SE FORME UNA PELICULA IMPERMEABLE AL OXIGENO, POR EJEMPLO UNA CAPA DE OXIDO DE CROMO FORMADA EN UNA ALEACION DE CROMO CON NIQUEL, HIERRO Y/O COBALTO. EL COMPUESTO PUEDE SER UTILIZADO COMO SUSTRATO DEL ANODO PARA EL RECIBRIMIENTO DE OXIFLUORURO DE CERIO UTILIZADO EN LA OBTENCION DE ALUMINIO POR EL PROCESO ELECTROLITICO.
