Abstract
The oxide layers on stainless steel formed by heating at various high tempe ratures and by dipping in LiF+BeF2 molten (Flibe) bath at 600 degreesC were characterized by CEMS. Hematite was a major iron product at 600 degreesC a nd fine oxides with paramagnetic Fe(III) species were produced at the highe r temperatures than 700 degreesC. The interface of stainless steel beneath oxide films was characterized as the hyperfine field distributions. Para-ma gnetic Fe(III) species were produced on Cr depleted layers in the Flibe bat h. CEMS is effective for simultaneous characterization of both oxide surfac e and interface layers of the ferritic stainless steel.
