Insoluble anodes for electroplating are coated on a titanium substrate (reticular, plate, ribbon, tube, etc.) with noble metal oxide coatings with high electrochemical catalytic properties, and the coatings contain highly stable valve metal oxides. The new insoluble titanium anode has a high electrochemical catalytic energy, and the oxygen evolution overpotential is about 0.5 V lower than the insoluble anode of the lead alloy, has significant energy saving, high stability, does not contaminate the plating solution, is lightweight, and is easy to replace. The oxygen evolution overpotential of the new insoluble titanium anode is also lower than the platinum insoluble anode, but its lifetime is increased by more than 1 time. Widely used in various electroplating applications as anodes or auxiliary anodes, it can replace conventional lead-based alloy anodes. Under the same conditions, it can reduce the tank voltage and save power consumption; Insoluble titanium anodes have good stability in the electroplating process (Chemistry, electrochemistry), long service life. This anode is widely used in nickel plating gold plating, chrome plating, galvanizing, copper plating and other non-ferrous metals plating industry.
