Insights on the effect of water content in carburizing gas mixtures on the metal dusting corrosion of iron
Published 2022“…At later stage, the formation of oxide scale leads to an elevated concentration of H<sub>2</sub>O/OH molecules on the surface due to the decrease in Fe affinity to dissociate water. This results into blocking the Fe catalytic sites leading to lower C and O diffusion to the bulk of the sample.…”
