研究了与模拟高温原生水中腐蚀沉积物形成相关的动电效应。设计微型流通池的目的是创建加速流动区域，以产生净阳极和阴极活性区域，其特征可以通过电极极化的测定来表征。如此极化的电极的测试后 XRD 和 GDOES 检查表明，氧化物沉积速率和氧化物结构强烈依赖于电化学腐蚀电位。这项工作强调了由流动电势产生的阳极过程的重要性，这可以导致增强的氧化物沉积。
Electrokinetic effects associated with corrosion deposit formation in simulated high temperature primary water have been investigated. A miniature flow cell was designed for the purpose of creating regions of accelerated flow to produce areas of net anodic and cathodic activity which may be characterised by determination of electrode polarisations. Post-test XRD and GDOES examination of so polarised electrodes showed that the rate of oxide deposition and the oxide structure was strongly dependent on the electrochemical corrosion potential. This work underlines the importance of anodic processes generated by streaming potentials which can lead to enhanced oxide deposition.
