TITANIUM ANODE WITH ACTIVE COATINGS FOR CATHODIC PROTECTION OF REINFORCED CONCRETE STRUCTURES

By modifing of traditional titanium anode coating and improvement of sintering technology.The Ru-Ti-Ir new coating anode was prepared.X-ray diffraction and EMS analysis indicated that crystalline grain of coating oxide is small and uniformity,achieving to nano grade.There had no crack in the surface of coating.Electrochemical inspection analysis indicated that electro catalysis activity and accelerating life time of electrode was obviously superior to traditional anode.This electrode had a good utilization effect in impressed current cathodic protection of reinforced concrete.
