THE STRUCTURE AND GROWTH OF PASSIVE FILMS ON IRON, CHROMIUM AND IRON-CHROMIUM ALLOYS

摘要

Synchrotron x-ray diffraction has been used to study the structure of surface oxide films on pure iron, pure chromium, and iron-chromium alloys. To augment these experimental findings, we have used ab-initio, total energy, pseudopotential calculations to study the energetics and electronic structure of the defects within the identified oxide phases, and we have attempted to integrate these results within a numerical model for passive film growth on pure iron in borate buffer solution.
