Abstract
La presente invención se relaciona a método para pasivar electrolíticamente una capa de cromo más externa o de aleación de cromo más externa para aumentar la resistencia a la corrosión de la misma, el método comprende las etapas de: (i) proporcionar un sustrato que comprende dicha capa de cromo más externa o de aleación de cromo más externa, (ii) proporcionar o elaborar una solución de pasivación ácida acuosa, la solución comprende - iones de cromo trivalente, - iones fosfato, - uno o más aniones de residuos de ácidos orgánicos, (iii) poner en contacto el sustrato con la solución de pasivación y hacer pasar una corriente eléctrica entre el sustrato, a manera de un cátodo y un ánodo, en la solución de pasivación de modo que se deposite una capa de pasivación en la capa más externa, en donde en la solución de pasivación, dichos iones de cromo trivalente se obtienen mediante la reducción química de cromo hexavalente en presencia de ácido fosfórico a través de al menos un agente reductor seleccionado a partir del grupo que consiste en peróxido de hidrógeno y agentes reductores orgánicos, con la condición de que durante o después del producto químico que reduce uno o más aniones de residuos de ácido orgánico, esté presente por primera vez en la solución de pasivación.
