Effects of La on microstructure and properties of RuO2-TiO2 titanium anode coating

Based on the Ru-Ti oxide coated titanium anode prepared by thermal decomposition, added innovatively lanthanum in the coating. And the effects of lanthanum on microstructure and properties of the coating were studied. The surface topography and properties of the anode were characterized by SEM, XRD and electrochemical work station tests. The results show that when the content of lanthanum is 1.875% and reaction temperature is 450, the surface topography and microstructure of the coating can be improved significantly and grain can be refined. Compared with the anode without La, catalytic activity can be developed efficiently by adding to La, and eventually saving energy can be achieved. ©, 2015, Editorial Office of Transactions of Materials and Heat Treatment.
