摘要
本文用交流阻抗技术,通过对钝化铬在中性H_3BO_3+Na_2B_4O_7溶液中添加了K_3Fe_2(CN)_6/K_4Fe(CN)_6氧化还原对溶液中的极化性能及交流阻抗特性的研究,讨论了铬的钝化膜的电路模型。
This report studies on polarization behaviour and A.C impedance character of pure chrome in nuetral solution of H3BO3-Na2B4O7 and in redox solution of H3BO3 - Na2B4O7 + K3Fe(CN) 6/K4Fe(CN) 6 by means of polarization curve and impedance techniques. A discussion on electrode reaction and electro-model of passive film are completed.
