用电化学阻抗、极化曲线、扫描电镜等测试手段研究单相Fe3Al和Fe3Al/ZrO2复合材料耐海水腐蚀性能。结果表明，浸蚀初期，材料的抗局部腐蚀能力由强到弱依次为单相Fe3Al>Fe3Al（75vol%）/ZrO2>Fe3Al（50vol%）/ZrO2，但随着浸泡时间的延长，Fe3Al（50vol%）/ZrO2复合材料的腐蚀速率下降较快；浸蚀30d后，其抗海水腐蚀性最好。
The experiment was carried out on the systematic contrast of the Fe3Al, Fe3Al(75vol%)/ZrO2 and Fe3Al（50vol%）/ZrO2 samples .With the methods of electrochemical impedance spectroscopy(EIS), polarization and SEM. Through establishing electrical model of the metal/solution and equivalent circuit(EC),it proved that the corrosio resistance of the composites is worse than the single-phase Fe3Al material after immersed in seawater for 1day. however, with the immersion time increasing , the corrosion rate of Fe3Al（50vol%）/ZrO2 sample decreased dramatically because of its special microstructure. finally the corrosion resistance of Fe3Al（50vol%）/ZrO2 was proved to be the best of the three materals.
