摘要: 本文介绍了大气腐蚀电化学监测的研究结果。试验表明,经我们改进的大气腐蚀电化学监测电池可精确地控制工作表面积,性能稳定,使用寿命长。对Fe-Cu和Fe-Zn两种电池的各种性能进行了比较,结果表明Fe-Zn电池的平行性、重现性和灵敏性都优于Fe-cu电池,是一种较理想的大气腐蚀电化学监测元件。采用监测电池研究了几种环境因素和室内试验条件对腐蚀过程的影响,结果表明大气相对湿度是影响腐蚀速率的决定性因素,它与腐蚀速率呈指数关系。

Abstract：In this paper the experimental results of electrochemical monitoring of atmospheric corrosion is reported. It is shown that the electrochemical monitoring cell modified by the present method has the advantages for more accurately controlling the working surface area, superior stability of work conditions and longer service life. Two types of cells Fe-Zn and Fe-Cu, which had been widely used, were compared. The Fe-Zn cell showed better reproducibility and sensitivity than Fe-Cu cell in a great mensure. It is considered to be an ideal electrochemical monitoring element. The effects of outdoor environmental factors and indoor experimental conditions inside the laboratory on corrosive processes were also investigated. It is found that the relative humidity is the most important factor to influence corrosion rate and the relationship between relative humidity and corrosion rate may be assumed as an exponential function.
