ABSTRACT An electrode for use in an electrolytic process is provided with a mixed oxide interface between a titanium base and an outer coating. The mixed oxide is formed at said interface by means of titanium from the base and noble metal from a solution containing a predetermined amount of HCl which attacks the titanium base surface. Slow drying provides a metal chloride mixture which is thermally converted to said mixed oxide of titanium and noble metal in a given ratio, whereby to protect the titanium base from oxidation, An outer coating of manganese dioxide or lead dioxide is electroplated on the mixed oxide layer so as to provide an inexpensive electrode with improved resistance to oxidation. This electrode can be used for various processes where a high resistance to oxidation is required, e.g. as a manganese dioxide anode in a metal electrowinning process or as a lead dioxide anode for electroflotation ox organic oxidation reactions.
