Abstract:
      The development history of the aluminum alloy sacrificial anode materials was discussed. This critical review outlined the research development of the aluminum alloy sacrificial anodes utilized in different environments, and reviewed the mechanism of their activation dissolution, and analyzed factor affecting electrochemical property of anode. The existing problems of aluminum alloy sacrificial anode technique were pointed out. And the trend of development of the aluminum alloy sacrificial anode materials was discussed. The anode materials under ordinary sea water conditions is highly developed while those under special working situations still require further development and improvement.
