动电位伏安法以及叠加交流电的交流阻抗测量是研究金属表面状态的有效手段。最初以Breiter为代表的德国电化学家们用它揭示了铂族金属表面上氢层和氧层的特性。后来对银镍上都做过类似的工作。对于较活泼的金属铁镉也都发表了相应的结果。至于实用价值较大的金属——锌,则在这方面的研究不够充分。在文献[6]中只详细地研究了与锌的钝化过程相联系的表面状态的变化。
Potentiometric voltammetry and AC impedance measurement superimposed on the AC surface is an effective means of research status. The first German electrochemists, represented by Breiter, used it to reveal the properties of the hydrogen and oxygen layers on the surface of platinum group metals. Later on Silver Nickel have done a similar job. For the more lively metal iron cadmium have also published the corresponding results. As for the more valuable metal - zinc, then the research in this area is not sufficient. In Ref. [6] only the changes of the surface states associated with the passivation of zinc are studied in detail.
