Abstract

Un método para presentar y revestir por inmersión en caliente de aluminio o aleaciones de aluminio en una tira de acero que contiene cromo, para proporcionar un revestimiento mejorado que comprende recocer tira de acero con calibre final en una atmósfera de oxígeno en exceso, para producir un óxido rico en cromo en la superficie y posteriormente decapar en forma electrolítica la tira en una solución de sal acuosa para retirar el óxido y para exponer una superficie agotada de cromo de la tira. La tira luego se transporta a una línea de revestimiento, en donde se calienta una temperatura en o por encima de la temperatura de un baño de aluminio o aleación de aluminio. Se mantiene una atmósfera substancial de hidrógeno sobre el baño mientras que el punto de rocío se mantiene por debajo de menos 35ºC. La tira luego se estira a través del baño para revestirla.
