Abstract

Cr⁶⁺, formed as CrO₃ along with Cr₂O₃ during the oxidation of pure chromium, is shown to reduce to Cr⁴⁺ (as CrO₂) in the course of X-ray photoelectron spectroscopy analysis. Chromate which formed as a result of surface hydration of the oxide film was less affected by irradiation. Estimates have been made of the amounts of CrO₃ and CrO₄ ^2- present in the oxide film prior to irradiation.
