摘要: 研制了一种多孔薄板结构的电化学探测电池,能按气体环境腐蚀性的强弱转换成电池电流输出。根据输出的电流及其积分电量可计算金属在气体中的瞬间及平均腐蚀速度。本文介绍这种探测电池的性能和使用范围,着重讨论碳钢电解电池的电流和真实腐蚀失重之间的关系,并列举了它们在大气,工业废气,高压管道天然气介质中在线腐蚀监测以及耐蚀材料筛选研究等方面的应用。

Abstract：An electrochemical monitoring cell consisting of two multi-holed plates sandwiched by a dielectric foil has been developed as corrosion sensors in the authors' lab. Based on the cell current and its accumulated quantity the mean or instantaneous corrosion rates of metals in gases can be measured and recorded continuously. In this paper the construction and characteristics of the sensors are described. For the carbon steel sensor in electrolytic cell,the quantitative relation between cell current and true weightloss defined as the cell's factor was studied. In addition,some applications of above sensors were illustrated and the results of on-line monitoring tests of corrosion in atmospheres or in industrial exhaust gases or inside natural gas pipeline were reported respectively.
