Effect of Water on the Corrosion Behavior of Mild Carbon Steel in E10 blend

The effect of phase separation in E10 blend upon water addition on the corrosion behavior of mild carbon steel was investigated using electrochemical and morphological techniques. Increase in water addition resulted in increase in corrosion kinetics of steel exposed to water-ethanol phase. Both uniform and localized corrosion were observed on areas of the steel surface in this phase, with the extent of corrosion being the greatest near the interface of the two separating phases.
