Abstract
The electrochemical behavior of iron in solution at 22° and 200°C has been investigated using cyclic voltammetry, galvanostatic charging, and steady‐state polarization techniques. At 22°C the data are consistent with the initial formation of and on the surface followed by the oxidation of iron to or . The anodic behavior of iron at 200°C can be explained by the following processes where process [1] accounts for active dissolution of iron, [2] for the direct formation of the base oxide layer from the metal, and [3] and [4] for the nucleation and growth of the “upper‐layer” oxide crystals.Keywords
