Abstract
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.
