“…The deformation rate of the Fe15Cr11Al2Si0.5Y-coated cladding tubes is 1%, 3%, 5%, and 50%, as shown in Figures 7(c) and (c 1 ). Note that the rapid increase in the load of the Fe15Cr11Al2Si0.5Y coated cladding tube after the deformation rate reached 50% was due to the contact between inner surfaces at the top and bottom positions [29]. It has been widely acknowledged that the thin coating (<20 μm) on the outer surface of the cladding tube is expected to have limited influence on the mechanical properties of the cladding tube [29,30].…”

It has been widely acknowledged that the thin coating (<20 μm) on the outer surface of the cladding tube is expected to have limited influence on the mechanical properties of the cladding tube [29,30]. There are two different stages in the mechanical failure of the coating on the outer surface of the cladding tube [31][32][33].…”

The high-temperature lead-bismuth eutectic (LBE) corrosion resistance and ring compression performance of the Fe15Cr11Al2Si, Fe15Cr11Al0.5Y, and Fe15Cr11Al2Si0.5Y coatings were investigated. Even if the corrosion test temperature reaches 800 ℃, all these coatings can effectively protect the steel cladding tube. After the corrosion test temperature exceeded 660 ℃, an obvious Al-rich oxide layer was formed on the surface of the coating, and Al element enrichment occurred at the interface between the coating and the substrate. After the corrosion test at 800 ℃, holes appeared in the thick interface layer of the Fe15Cr11Al2Si0.5Y coating. The Fe15Cr11Al2Si coating cracked after the ring compression test with a deformation rate of 3%, and the coating peeled off after the deformation rate reached 5%. When the deformation rate reached 5%, there was still no cracking in the Fe15Cr11Al0.5Y coating. When the deformation rate reached 30%, the coating cracked, but the cracked coating was still tightly bonded with the substrate. The Fe15Cr11Al2Si0.5Y coating has the worst compression performance, even if the deformation rate is 1%, the coating still peels off obviously. The underlying mechanism for the evolution of corrosion resistance and compression performance was discussed.
