摘要: 為了搞清鎳的鈍化行為,本文用極化曲線法及交流阻抗技術,通過對純鎳在中性H3BO3-Na2B4O7溶液及添加了K3Fe(CN)6/K4Fe(CN)6氧化-還原系溶液中的極化行為及交流阻抗特性的研究,討論了鈍化膜的電模型和電極反應。Abstract: This report described a study on polarization behaviour and AC impedance character of pure nidkel in neutral 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. The electrode reaction and electro-model of passive film are also discussed.
