The Effects of Hydrogen on Properties of Surface Films Formed on Iron in Sulfate Solutions

Abstract:

The effects of charged hydrogen in iron on surface properties of iron in pure water and sodium sulfate solutions of various concentrations were investigsted by open circuit potential monitoring, surface morphology observations, Raman spectroscopy and XRD measurements. Hydrogen in iron shifed the open circuit potential in the negative directions. Hydrogen could change the types of oxide film on iron. Effects of hydrogen on corrosion of iron was More significant in pure water and dilute sodium solutions than those in concentrated solutions.
