电化学阻抗谱研究的镍-铁共沉积的结果。阻抗谱的影响，在一个复杂的方式所施加的电流密度，转速，和浓度的亚铁离子。光谱对电流密度和亚铁离子浓度特别敏感。作为比较的基础，本文介绍了无铁镀液中镍沉积的实验和理论研究。结果表明，亚铁离子存在时，阻抗谱中的感应圈变化最大。
Results of an electrochemical impedance spectroscopy study of nickel-iron codeposition are presented. Impedance spectra are influenced in a complicated manner by the applied current density, rotation speed, and concentration of ferrous ions. Spectra are particularly sensitive to current density and ferrous-ion concentration. As a basis for comparison, an experimental and t eoretical study of nickel deposition from an iron-free bath is presented. It is found that it is the inductive loop of the impedance spectra that changes most dramatically in the presence of ferrous ions.
