本研究分析了一种基于应变测量的大气腐蚀传感器（ACSSM），并采用主动假人方法进行了腐蚀产物实验。进行了初始补偿热应变实验。进一步的分析采用干湿环境和盐水喷雾来研究腐蚀产物对低碳钢样品的减薄性能。采用有源假人方法的ACSSM精确测量了试样厚度减小引起的信号，尽管信号中存在噪声。此外，还讨论了腐蚀产物对信号的影响。
This study analyzed an atmospheric corrosion sensor using strain measurements (ACSSM) with an active dummy method for corrosion product experiments. An initial compensation thermal strain experiment was performed with elapsed time. Further analyses used dry-wet environments with salt water spray to investigate the thickness reduction performance of the corrosion product on low-carbon steel samples. The ACSSM with an active dummy method accurately measured signals induced by the specimen thickness reduction, despite the noise in the signal. Moreover, the effects of corrosion products on the signal were discussed.
