摘要 利用以基体产生—探针收集工作模式为基础的扫描电化学显微镜(SECM)面扫描技术,通过测量不锈钢基体电极表面的Faraday电流图像,并与循环伏安结果相结合,获得与基体表面电化学活性有关的反应产物组成及浓度等信息. By means of area scan technique in a mode of substrate generation-tip collection （ SG-TC ） of scanning electrochemical microscope （SECM）, the information such as compositions of electrolyte and concentrations of corrosion product related to the electrochemical activities of stainless steel substrate surface has been acquired by measuring the Faraday current images on the substrate electrode surface in combination with the results of cyclic voltammogram （CV）.
