Abstract
A metal-based anode substrate of a cell for the electrowinning of aluminium comprises a nickel-alloy based core, a layer of silver on the core and a layer comprising nickel and iron covering the silver layer and serving as an anchorage layer for anchoring an electrochemically active surface coating on top of the anode substrate. The electrochemically active coating may be a cerium-based coating. The silver layer inhibits diffusion of fluoride species into the core and prevents interdiffusion of constituents of the core and constituents of the anchorage layer.
