Abstract

A plate for use as the cathode in an electrolytic cell in which zinc is deposited onto the plate from an acidic solution of a zinc salt, wherein the plate is arranged to be supported vertically and partially immersed in the solution, and wherein the plate is composed of an aluminium alloy of less than 99.85% by weight purity, characterised in that in the region of the plate where in use the level of the solution in the cell on the plate will lie the plate carries on each of its two faces a surface layer of aluminium having a purity of at least 99.80% by weight and wherein the compositional difference between the plate and the surface layer is at least 0.2% by weight of aluminium.
