Study on Nano-crystal IrO2-Ta2O5 Oxide Coat Anode on Titanium Substrate

Preparation and electrochemical performance of nano- crystal IrO2-Ta2O5 oxide coat on titanium substrate are studied by scanning electron microscope, X-ray diffractometer, and cyclic vmltammetry test and accelerated aging test methods. Such factors as mechanic pre-treatment of titanium substrate and compositions of the film will influence particle size of the nano- crystal oxide in its thermolysis preparation, resulting in the change of electrochemical performance of the oxide anode.
