Abstract
Mixed metal oxide coated titanium anodes prepared by thermal decomposition were characterized by scanning electron microscopy and electrochemical measurement, while the consumption rate of an anode was also measured in seawater. In order to examine the practical performances of mixed metal oxide_coated anodes, a simulating test on floating dock in seawater has also been carried out. The SEM results indicate that oxide layers exhibited a cracked_mud morphology which endows the anode with good electrocatalytic activity. The electrochemical measurements showed that mixed metal oxide_coated anodes exhibit excellent electrochemical activity and electrochemical stability in seawater. Owing to good corrosion resistance and low consumption rate in seawater, the mixed metal oxide coated anodes belong to insoluble material,which are outstanding candidates for use as anode in impressed current cathodic protection systems.
