采用交流阻抗技术，在自然大气环境中对含镍钢进行了腐蚀监测。采用一对相同的镶嵌在环氧树脂中的梳状钢电极作为腐蚀监测的探针电极。将普通碳钢、含镍2.5%和含镍5%的钢三种不同的探头暴露在自然海洋大气中14个月。通过连续测量极化电阻来监测钢的瞬时腐蚀速率，并由高频阻抗确定钢表面的润湿时间。测量由放置在暴露现场的交流腐蚀监测器自动进行，暴露现场和实验室之间的数据传输通过手机进行。
Corrosion monitoring of nickel-containing steels has been performed in a natural atmospheric environment using AC impedance technique. A pair of identical comb-shape steel electrodes embedded in epoxy resin was used as a probe electrode for the corrosion monitoring. Three different probes of ordinary carbon steel, 2.5%Ni- and 5%Ni-containing steels were exposed to a natural marine atmosphere for the period of 14 months. The instantaneous corrosion rate of the steels was monitored by continuous measurements of the polarization resistance, and time of wetness of the steel surface was determined from high frequency impedance. The measurement was automatically carried out with an AC corrosion monitor placed at the exposure site, and data transmission between the exposure site and laboratory was performed through cellular phones.
