The effects of Si‐ion implantation and preoxidation on the corrosion behavior of a new steel SIMP in 550∘C ${\bf{55}}{{\bf{0}}}^{\circ }{\bf{C}}$ lead‐bismuth eutectic

Abstract

To improve the corrosion resistance of SIMP steel, we have investigated Si‐ion implantation and preoxidation effects on the corrosion behavior of SIMP steel samples, which have been in stagnant lead‐bismuth eutectic (LBE) with saturated oxygen at C for 1000 h. It was found that increasing Si content on the surface did not improve corrosion resistance performance. By contrast, the preoxidized sample demonstrated high resistance to LBE corrosion due to the presence of a thin Cr‐enriched oxide layer.
