Applicability of Al-Powder-Alloy Coating to Corrosion Barriers of 316SS in Liquid Lead-Bismuth Eutectic

A new Al-alloy coating method using Al, Ti and Fe powders has been applied to 316SS in order to develop corrosion resistant coating in liquid lead-bismuth eutectic (LBE). The 316SS plates with coating layers of different Al concentrations were exposed to liquid LBE with controlled oxygen concentrations of 10 À6 to 10 À4 mass% at 823 K for 3600 ks. While surface oxidation and grain boundary corrosion accompanied by liquid LBE penetration are observed in 316SS without Al-alloy coating, the Al-alloy coating is effective to protect such severe corrosion attacks in liquid LBE. Although the coating layer containing 2.8 mass% Al does not always keep sufficient corrosion resistance, good corrosion resistance is obtained through the Al-oxide film formed in liquid LBE in the coating layer where the average Al concentration is 4.2 mass%. Cracks are formed in the coating layer containing 17.8 mass% Al during the coating process. The Al-powder-alloy coating applied to 316SS is promising as a corrosion resistant coating method in liquid LBE environment.

“…After exposure to oxygen-controlled LBE at 823K for 3000 hrs, and 85 s of sputtering, the surface of the annealed sample is primarily iron oxide (Fe/Cr = 6.5) , whereas the cold-rolled 8 sample had large chromium content (Fe/Cr = 2.7). While there is still large carbon contamination, the residual lead and bismuth falls below 1 atom % in both cases, indicating that there is little to no penetration of the LBE into the forming oxide layers.…”

The corrosion of steel by lead-bismuth eutectic (LBE) is an important issue in proposed nuclear transmutation schemes. Steel samples were exposed to oxygen-controlled LBE at high temperature and exposure times that simulate actual reactor systems. Scanning electron microscopy (SEM), combined with energy-dispersive X-ray analysis (EDAX) and X-ray photoelectron spectroscopy (XPS), has been used to study post-exposure steel samples and unexposed controls. Our investigation of the reacted samples revealed preferential segregation of metals contained in the initial alloy formulations. Sputter depth profiling of the exposed annealed sample and cold-rolled sample showed a marked difference in oxide layer composition, depending on surface preparation. The annealed sample showed a complex oxide structure (iron oxide over chromium/iron oxide mixtures) of tens of microns thickness. The cold-rolled sample was covered with a rather simple, primarily chromium oxide layer of ~1 micron thickness. The cold-rolled sample had an order of magnitude less corrosion (i.e., both lower oxidation and less weight change) than the annealed sample.3

“…[3][4][5][6][7][8][9][10] It is pointed out that corrosion mechanism in LBE changes from protective oxidation to dissolution above 500 C while it depends on oxygen concentration and types of steels. [4][5][6][7][8][9][10] However, there are unclear points to make a quantitative prediction about corrosion in LBE because the obtained experimental data are still insufficient and scattered. Phenomena such as oxidation, grain boundary corrosion/ internal oxidation, penetration of LBE and dissolution of elements occur in LBE corrosion.…”
