PERMANENT ANODE FOR PROCESS OF HIGH CURRENT DENSITY ZINC PLATING

摘要

A dimensionally stable anode for high-speed galvanizing processes is constituted by at least two electrodic layers. The current density is substantially the same for each single layer and does not exceed the value corresponding to the minimum desired lifetime of the anode. A suitable number of electrodic layers is provided in order to obtain a total current density at the anode in the same range of values as those required for high-speed electrogalvanizing. The anode further comprises a suitable device for preventing short-circuits.
