Abstract
La presente invención se refiere a un proceso para tratar una superficie de zinc, que comprende poner en contacto la superficie de zinc, durante un tiempo suficiente para oscurecer la superficie con un líquido de tratamiento que es una solución acuosa alcalina que tiene un pH de entre aproximadamente 7 y aproximadamente 11.0, y que consiste esecialmente de por lo menos aproximadamente 1.0 g/L de iones Ni2+ y suficiente NH3 para dar una proporción molar de NH3 a iones de Ni2+ en la solución de tratamiento, de por lo menos aproximadamente 6.
