“…The inner FeCr-spinel oxide layer remained intact, even at a flow rate of v ≈ 3 m/s. A similar erosion/corrosion effect was observed in 410 steels (Fe-12Cr) exposed to oxygen-saturated, flowing LBE at 550 • C for 600 h by Chen et al [193]. In that study, however, the outer magnetite scale was not removed by the LBE flow for a velocity up to v ≈ 2.98 m/s.…”

“…Some red lead oxides were observed on the surface of LBE and the inner wall of the crucible, indicating that the LBE was saturated with oxygen. [ 18–20 ] The oxygen concentration in the liquid LBE is 6.3 × 10 −4 wt%, which was calculated from the following equation [ 21 ] :

\log C (wt %) = 1.2 - \frac{3400}{T (normalK)} .

For lead‐cooled fast reactors and accelerator‐driven subcritical systems, the surface corrosion behavior of candidate structural materials in lead–bismuth eutectic (LBE) is a key issue, which determines whether the material is applicable. The candidate materials of two typical MAX phases, Ti3SiC2 and Ti3AlC2, were immersed in static LBE with saturated oxygen concentration at 500°C for up to 3000 h. The corrosion behaviors of Ti3SiC2 and Ti3AlC2 were analyzed by scanning electron microscope, energy‐dispersive X‐ray, X‐ray diffraction, and Raman spectra. The experimental results showed that elements interdiffusion between LBE and sample matrix occurred on both Ti3SiC2 and Ti3AlC2 surfaces, which led to the formation of the diffusion layer. The dominant component of the diffusion layer is PbTiO3, which makes the corroded surface fragile in a stress environment. Besides, there were differences in structures of corroded sample surfaces between Ti3SiC2 and Ti3AlC2. The corrosion layer of Ti3SiC2 consisted of two layers, while only one single layer formed on Ti3AlC2 surfaces. The stable oxide layer consisting of SiO2 and TiO2 can protect Ti3SiC2 samples from further LBE corrosion and maintain the integrity of the surfaces. For Ti3AlC2 samples, it is hard to form a continuous Al2O3 protective layer, thus no stable oxide layer was detected on the corroded surfaces. Compared with Ti3AlC2, Ti3SiC2 showed better corrosion resistance in LBE.

“…This indicates that the Y 2 O 3 addition showed less influence on the corrosion resistance in static LBE. For the 304SS surface in Figure 10l, an oxide scale grew to ~10.4 µm after 1000 h of exposure in the static LBE, which could be determined as (Fe,Cr) 3 O 4 [2,3,48]. After 1000 h of corrosion, the oxide scale of 304SS grew to an average ~10.4 µm.…”

In order to prevent the lead-bismuth eutectic (LBE) corrosion of stainless-steel components used in nuclear reactors, the FeCrAlTiC-xY2O3 coatings were prepared on 304 stainless steel (304SS) by laser cladding. After adding Y2O3, Y2TiO5 and Y2Ti2O7 formed, which have a combined strengthening effect on improving hardness. The 0.2 wt.% Y2O3 coating showed the highest hardness as ~489 HV. In the 400 °C wear test, the weight loss of coating samples was less than ~5.2 mg, while the weight loss of 304SS samples was ~35.5 mg. The 0 wt.% Y2O3 coating showed the highest wear resistance, indicating that adding Y2O3 could result in the decrease of wear resistance. The LBE corrosion behaviors of coatings at 500 °C were investigated. The results showed that a uniform and dense oxide scale with a low growth rate was obtained on the coating surface, and no penetration of LBE into the coating was observed. After 1000 h of corrosion, the oxide scale of coatings grew to merely a ~0.3 μm thickness. The corrosion resistance mechanism of the coating in oxygen-saturated LBE at 500 °C was proposed based on experimental results along with a thermodynamic and kinetic analysis.
