Visualising the dynamic processes of flow accelerated corrosion and erosion corrosion using an electrochemically integrated electrode array

An electrochemically integrated and individually addressable multi-electrode array has been proposed and demonstrated as a new tool for simulating, visualising and monitoring the dynamic processes of flow accelerated corrosion (FAC) and erosion corrosion under natural corrosion conditions. It has been shown for the first time that FAC and erosion corrosion are able to evolve and propagate freely on the electrode array surface, and that similar corrosion patterns have been observed on the array and coupon surfaces after being exposed to the same flow condition. This method has enabled the visualisation of FAC and erosion corrosion processes with high spatial and temporal resolutions, providing a new means of probing, monitoring and assessing FAC and erosion corrosion and their prevention.
