摘要：
Corrosion of filings from an ASTM Grade 60 steel reinforcing bar was examined in situ using the soft X-ray transmission microscope XM-1, operated by the Center for X-ray Optics and located at the Advanced Light Source at E.O. Lawrence Berkeley National Laboratory. Iron distribution maps generated from X-ray images of a steel filing before and after the addition of water show the change in elemental iron distribution in the sample. The decreased presence of iron in the distribution map after the introduction of water indicates the oxidation of iron - the anodic reaction in steel corrosion. These results demonstrate the utility of transmission soft X-ray microscopy for in, situ corrosion studies. (C) 2000 Elsevier Science Ltd. All rights reserved.
