The compatibility of cladding material with lead-bismuth eutectic (LBE) above 600 °C poses a critical challenge in the implementation of lead-bismuth fast-cooled stacks. Consequently, we fabricated three coatings of Al + Al2O3, FeAl, and FeAl + Al2O3 using ferritic/martensitic steel as the substrate through multi-arc ion plating. We evaluated the microstructure and hardness of the substrate and coatings, in addition to exploring the samples' corrosion resistance through static LBE corrosion at 600 °C for 1000 hours. Our findings indicate that all three coatings exhibited exceptional corrosion resistance under high-temperature lead-bismuth, and the thickness of the oxide layer formed by corrosion was reduced by 60 pct in comparison to that of the uncoated sample. The oxide layer was composed of Fe3O4, Al2O3, and FeCr2O4. During the corrosion process, lead-bismuth infiltrated the oxide layer through the pores, leading to oxidation of the inner fresh coating, while the outer oxide layer underwent crack expansion with pores at the core.
