Abstract

Método para controlar la composición de una solución de decapado, caracterizado porque en el decapado para acero inoxidable que emplea un baño de sulfato férrico-ácido fluorhídrico, el potencial de oxidación-reducción de la solución de decapado se mantiene en un intervalo previamente determinado añadiendo peróxido de hidrógeno y ácido sulfúrico en la solución de decapado.
