摘要：
Interfacial enrichment of iron during anodic oxide growth on an Al6Fe phase has been confirmed by examination of the oxide/Al6Fe interface in a field-emission and energy-filtering transmission electron microscope, with images obtained using electrons which have suffered a particular loss of energy. The iron enrichment is confined to a thin layer, 1-2 nm thick, immediately beneath the anodic oxide. The composition of the iron-enriched layer, determined by EDX analysis, using an electron probe of diameter of about 1 nm, is Al80.5Fe19.5. The impact of energy-filtering transmission electron microscopy for corrosion studies is also considered. (C) 1999 Elsevier Science Ltd. All rights reserved.
