摘要：
The corrosion product films that were formed on industrial, low-carbon concentration Fe-C steel after immersion in diluted ammoniac solutions were investigated by 57 Fe Mossbauer spectroscopy. The amorphous Fe3+ oxyhydroxide was the major constituent of the corrosion layers. Layer thickness increased as NH3 concentration changed from 10(-1) to 10(-4) N. All GEMS spectra indicated a magnetic anisotropy on the surface of the samples. (C) 2004 Elsevier B.V. All rights reserved.
