Corrosion mechanism of reduced activation ferritic martensitic steel JLF-1 in liquid metal Sn
Source abstract
Abstract
Reduced activation ferritic martensitic steel JLF-1 (Fe-9Cr-2 W-0.1 C) corroded in liquid Sn at 673–873 K due to the formation of intermetallic compound layers. The outward growth of FeSn 2 layer at 773 K was rate-controlled by a boundary diffusion. The inward growth of FeSn-like layer was recognized in the exposure for more than 250 h. The FeSn growth progressed according to the diffusion of Sn along the boundaries of martensite structure. Thin Cr 2O 3 layer formed by a pre-oxidation treatment did not function as an anti-corrosion layer in liquid Sn, though the sintered specimens of Fe 2O 3 and Cr 2O 3 revealed corrosion resistance.
