Abstract
CEMS and X-ray diffraction of rust layers on an iron coupon corroded in a 0.02 M KCl solution show that there exists a magnetite layer below an outer lepidocrocite layer. The 10 K spectrum displays three ferric sextets in its lepidocrocite part with fields of 448, 422 and 387 kOe respectively. They are attributed to Fe3+ ions having zero, one and more Cl− ions as first nearest neighbours. The Cl− ions do not seem to be ordered.
