Abstract
Un método para el tratamiento de superficies con porciones corroídas por oxidación, caracterizado porque incluye la aplicación a la superficie de un líquido, que contiene en una solución acuosa, por lo menos dos substancias compatibles, siendo la primera de las substancias de un tipo y estando en concentración sustancial para efectuar una conversión mediante la reducción de la porción oxidada de la superficie del material, y siendo la segunda sustancia de un tipo y de una concentración que, significativamente retardan la movilidad de las porciones activas de la primera substancia, y, por tanto, el índice de conversión mediante reducción efectuado por dicha primera substancia.
