Abstract

La presente invención se refiere a un método controlado para depositar una capa de cromo o aleación cromo sobre al menos un sustrato, el método comprende los pasos de (a) proporcionar un baño de deposición acuoso, donde el baño comprende-iones de cromo trivalente, -iones de bromuro, -cationes de metal alcalinos en una cantidad total de 0 mol/L hasta 1 mol/L, sobre la base del volumen total del baño de deposición, y el baño tiene - un pH objetivo dentro del intervalo de 4.1 a 7.0, (b) proporcionar al menos un sustrato y al menos un ánodo, (c) sumergir al menos un sustrato en el baño de deposición acuoso y aplicar una corriente eléctrica directa de modo que la capa de cromo o aleación de cromo se deposite sobre el sustrato, siendo el sustrato el cátodo, donde durante o después del paso (c) el pH del baño de deposición es menor que el pH objetivo, (d) agregar NH4OH y/o NH3 durante o después del paso (c) al baño de deposición de modo que el pH objetivo del baño de deposición se recupere.
