Abstract

Procedimiento para la segregación galvánica de cromo duro sobre un sustrato a partir de una solución electrolítica que contiene Cr(II) o mezclas de Cr(II) y Cr(III), así como halogenuros, caracterizado porque la formación de halógeno elemental se impide por utilización de un ánodo soluble o porque el halógeno elemental que se origina durante la segregación forma un complejo con un formador de complejos, el cual es un compuesto de amonio cuaternario.
