450$$^{circ}$$C及び550$$^{circ}$$Cの酸素飽和した液体鉛ビスマス中で、Al表面処理を行った種々のレベルのCrを含む鋼について、3000時間の腐食試験を実施した。Al表面処理法として、ガス拡散法及び溶融Al浸漬法の2種類を採用した。ガス拡散法によって作られたAl$$_{2}$$O$$_{3}$$, FeAl$$_{2}$$及びAlCr$$_{2}$$は液体鉛ビスマスに対して耐食性を示したが、溶融Al浸漬法によって作られた表面層では著しい腐食が起こった。溶融Al浸漬法によって作られたFe$$_{4}$$Al$$_{13}$$及びFe$$_{2}$$Al$$_{5}$$は550$$^{circ}$$Cの腐食試験中に消失し、FeAlだけが残存した。

Corrosion tests were performed in oxygen-saturated liquid Pb-Bi at 450$$^{circ}$$C and 550$$^{circ}$$C in a pot for 3000h for Al-surface-treated steels containing various levels of Cr contents. The Al surface treatments were achieved using a gas diffusion method and a melt dipping method. Al$$_{2}$$O$$_{3}$$, FeAl$$_{2}$$ and AlCr$$_{2}$$ produced by the gas diffusion method exhibited corrosion resistance to liquid Pb-Bi, while the surface layer produced by the melt dipping method suffered a severe corrosion attack. Fe$$_{4}$$Al$$_{13}$$ and Fe$$_{2}$$Al$$_{5}$$ produced by the melt dipping method disappeared during the corrosion test at 550$$^{circ}$$C and only FeAl remained.
