摘要: 本文用交流阻抗技術,通過對鈍化鉻在中性H3BO3+Na2B4O7溶液中添加了K3Fe2(CN)6/K4Fe(CN)6氧化還原對溶液中的極化性能及交流阻抗特性的研究,討論了鉻的鈍化膜的電路模型。Abstract: 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.
