摘要
为了搞清镍的钝化行为,本文用极化曲线法及交流阻抗技术,通过对纯镍在中性H_3BO_33-Na_2B_4O_7溶液及添加了K_3Fe(CN)_6/K_4Fe(CN)_6氧化-还原系溶液中的极化行为及交流阻抗特性的研究,讨论了钝化膜的电模型和电极反应。
This report described a study on polarization behaviour andAC impedance character of pure nidkel in neutral solution of H3BO3-Na2 B4O7 and in redox solution of H3BO 3-Na2 B4O7 + K3Fe (CN) 6 / K4Fe(CN)6by means of polarization curve and impedance techniques. The electrode reaction and electro-model of passive film ar ealso discussed.
