论文摘要
使用电化学阻抗光谱研究研究了200 OC的液态铅丝晶（LBE）中氧化铁的阻抗行为。比较了在不同温度和持续时间在空气中氧化的铁上生长的氧化物的结构和抗性。结果表明，由于形成较厚的尺度和较少的缺陷，氧化物膜的阻力随氧化温度的升高而增加。在相同的温度（600 OC）下，增加氧化时间还可以降低氧化物膜中的缺陷浓度并改善LBE中氧化物尺度的阻抗。
The impedance behavior of pre-oxidized iron in liquid lead-bismuth eutectic (LBE) at 200 oC is studied using electrochemical impedance spectroscopy. The structures and resistance of oxide grown on iron oxidized in air at different temperatures and durations are compared. The results show that the resistance of the oxide film increases with increasing oxidizing temperature, due to the formation of a thicker scale and fewer defects. At the same temperature (600 oC), increasing the oxidation time can also reduce the defect concentration in the oxide film and improve the impedance of the oxide scale in LBE.
