Compatibility of surface-coated steels, refractory metals and ceramics to high temperature lead–bismuth eutectic

Corrosion characteristics of materials in Pb–Bi under transient temperature conditions

“…The shapes of molybdenum for transient temperature case-1 and case-2 were rectangular with 10.5 Â 4.5 Â 2 mm and 7.6 Â 5.6 Â 2 mm in sizes, respectively. According to the previous report, molybdenum exhibits high corrosion resistance to Pb-Bi at 700°C [4].…”

“…The UBMS method which was applied in this study was already described in Ref. [4]. The UBMS technique was applied to HCM12A and SUS316 steels in two different times and conditions.…”

“…The detail of corrosion test apparatus was already described in Ref. [4]. The apparatus consists of a steam generator, a moisture dew-point sensor, a heater section, an oxygen sensor, a test pot and a gas exhaust system.…”

“…surface-treated steels, high chromium steels, refractory metals and ceramics [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. However, for practical application the materials have to have high corrosion resistance from corrosion attack of lead alloy not only under normal condition but also in the temporary anomalous conditions.…”

“…UBMS technique as the surface treatment steels method to protect the steels' surface from corrosion attack has been widely used because of the benefits of deposit adherent, fully dense films for pure metals and alloys [23][24][25][26]. It was reported that the UBMS technique could effectively protect the surface of steel from corrosion attack of Pb-Bi at 700°C [4]. However, corrosion behavior of the sputtering layer produced by using UBMS technique to protect the steel from corrosion attack of Pb-Bi under transient temperature conditions is very limited.…”
