Abstract A new type of PbO2-coated metal anode, useful for electrochemical processing requiring the use of high-overpotential anodes, was prepared by applying to a titanium substrate an undercoating of Ti-Ta oxides, then covering the undercoating with an intermediate coating of stress-free α-PbO2 deposit, and finally covering the intermediate coating with a Ta2O5 particle-admixed β-PbO2 deposit. The anode thus produced was found to be superior to the anodized Pb or platinized Ti anode in respect of oxygen overvoltage, and corrosion resistance, even in solutions containing organic solvents. The possibility for use in chromium plating is also indicated.
