Abstract

MASCARA DE APERTURA QUE CONSTA DE UNA ALEACION DE NIQUEL-HIERRO, CON BAJA EXPANSION TERMICA, PARA UN TUBO DE COLOR DE RAYOS CATODICOS. SE OBTIENE COMBINANDO UNA PRIMERA OPERACION DE FIJACION PARA PRODUCIR UNA FUERZA COERCITIVA BAJA Y UNAS PROPIEDADES MECANICAS APROPIADAS PARA UNA OPERACION DE CONFORMACION EN CALIENTE DURANTE LA CUAL SE OBTIENE EL PERFIL DESEADO DE LA MASCARA CON RECUPERACION ELASTICA MINIMA Y UNA SEGUNDA FASE DE FIJACION TRAS LA FORMACION PARA OBTENER UNA MASCARA DE FUERZA COERCITIVA BAJA LIBRE DE ESFUERZOS QUE TIENE UNA SUPERFICIE OXIDADA DE ALTA EMISION TERMICA. EL PROCESO REQUIERE EL CONTROL DE LAS ATMOSFERAS Y LOS POTENCIALES DE OXIDACION EN AMBAS FASES.
