ANODIC STRUCTURE FOR HORIZONTAL CELLS FOR PROCESSES OF METAL ELECTRODEPOSITION

摘要

2The present invention concerns an electrode for oxygen evolution in electroplating plants comprising a valve metal substrate and an outer catalytic layer the substrate consisting of a metal plate provided with slits of area ranging from 2 to 8 cm said slits being spaced apart by a distance of 5 to 25 cm. The invention also concerns a horizontal electrochemical cell for electroplating processes comprising at least one of said electrodes and an electroplating plant equipped with at least one of said cells. The invention also concerns an electroplating process comprising the step of anodically evolving oxygen on the surface of said electrode.
