Abstract: In order to study the corrosion behavior of martensitic stainless steel 410 in lead-bismuth eutectic alloy (LBE) at high temperature with different relative velocities, the article investigated the corrosion phenomena of stainless steel 410 in lead-bismuth eutectic alloy at 550 ℃ for 600 h with relative velocities of 0 m/s, 1.70 m/s, 2.31 m/s and 2.98 m/s. X-ray diffraction (XRD), scanning electron microscopes (SEM) and energy dispersive spectrometry (EDS) were carried out on the surface and cross-section of corrosive samples with different relative velocities. The results indicate that the oxide layer becomes denser and thicker on the surface of corrosion samples with the increase of relative flow rate, due to the increase of mass transfer rate accelerates the formation rate of oxide layer. The oxide layer on the surface of corrosion samples can be divi-ded into outer oxide layer and inner oxide layer. The outer oxide layer is mainly composed of Fe3O4 and partially infiltrated Pb-Bi and the inner oxide layer is mainly spinel (Fe, Cr)3O4. Intergranular-corrosion and oxidation-corrosion occurred simultaneously during the corrosion process.
