The FeCrAlTiNb high-entropy alloy coatings are fabricated by magnetron sputtering method to prevent the lead-bismuth eutectic (LBE) corrosion of structural components used in lead-cooled fast reactors, and their microstructure, mechanical properties and LBE corrosion behavior are investigated systematically. The coatings exhibit significantly improved hardness, creep and wear resistance compared with ferritic/martensitic (F/M) steel. Moreover, the coatings show promising LBE corrosion resistance with parabolic oxidation rate constant 3~5 orders of magnitude lower than other candidate steels, which is ascribed to their intrinsic amorphous structure and the formation of protective FeCr2O4/Cr2O3 double-layer. Finally, the growth of oxide scale is discussed in detail.
