Abstract

Abstract:

Static corrosion of 316L stainless steel (SS) in liquid lithium at 350°C, 0.15MPa, 500h was studied by corrosion weight loss, SEM and Metallographic analysis, and penetration depth of liquid lithium was represented by LIBS combined with step profiler. The result show that average corrosion ratio of 316L SS sample (containing weld) was 99.8mg·m^-2·h^-1, corrosion depth was 6.4μm, and in weld of 316L SS the penetration depth was 8.6μm, and in base metal it was 4.8μm. There was significant intergranular corrosion of lithium to material at the weld.

Key words: Liquid lithium, 316L stainless steel, Weld corrosion, LIBS

摘要：

通过失重法结合SEM、金相分析等手段，研究了含焊缝的316L 不锈钢试样在350°C、0.15MPa 液态锂中500h 的静态腐蚀，并采用LIBS 结合台阶仪表征液态锂的渗入深度。结果表明，锂对含焊缝的316L 不锈钢样式的平均腐蚀速率为99.8mg·m^-2·h^-1；腐蚀深度为6.4μm；渗入深度在316L 不锈钢焊缝处为8.6μm，在母材处为4.8μm。在焊缝处锂对材料有明显的晶间腐蚀。
