Novel insoluble titanium anode has high electro-chemical catalysis performance, and the oxygen evolution over-potential is about 0.5V lower than lead alloy insoluble anode. The insoluble titanium anode is featured with remarkable energy conservation, high stability, no pollution to plating liquid, light weight and easy change. In comparison with platinum-plated insoluble anode, the novel insoluble titanium anode is lower in oxygen evolution over-potential and is longer in service life which is greater than 1 time. The insoluble titanium anode can be used as anode or auxiliary anode in various electroplating processes and can replace conventional lead-base alloy anode. Under same condition, the insoluble titanium anode can reduce bath voltage and save electric consumption, and can ensure good (chemical/electro-chemical) stability and long service life in the electroplating process. The anode can be widely used in nickel/gold plating, chrome plating, zinc plating, copper plating and electroplating industries of other non-ferrous metals.
