Abstract: The invention relates to an electrode suitable for electrolytic treatments of dilute solutions of sodium chloride even at low temperatures. The electrode can be used in the generation of active chlorine-based biocidal agents in ballast water for marine applications. The electrode has a titanium substrate, an inner catalytic coating containing oxides of tantalum, ruthenium and iridium, and an outer catalytic coating containing oxides of titanium, ruthenium and of at least one of nickel, iron and cobalt.

Abstract: The invention relates to a catalytic coating of surfaces of valve metals, for example titanium, suitable for operation in highly aggressive electrolytic environments such as electrolysis cells of hydrochloric acid. The coating may be used as catalytic activation of electrodes, for example for anodic evolution of chlorine, or for protection from crevice corrosion of flanges and other elements of electrolysers subject to stagnation of liquid.
