The reduction of magnetite by hydrogen to soluble ferrous ions is an important factor in the corrosion behavior of steels in high temperature water. The morphology of the oxide formed in alkaline solutions is closely related to the direction of hydrogen diffusion. When hydrogen in evolved in the solution, a double layer is formed, whereas when hydrogen diffuses through the metal, a thin and compact layer of oxide is formed. The soluble iron content is dependent on the hydrogen concentration in a simulated PWR primary coolant environment.
