采用溶胶-凝胶法在316ss奥氏体不锈钢表面形成er2o3涂层。结果表明，在973K的高纯流动氩气中焙烧，涂层结晶效果良好，焙烧气氛中少量的氧气对涂层的结晶是必要的。为保证涂层的良好结晶，避免钢基体的强烈氧化，最佳的焙烧温度为973K。通过对涂覆和裸涂覆的316ss进行氘渗透试验，评价er2o3溶胶-凝胶涂层作为潜在氚渗透屏障的性能。在本研究中，包覆316ss的氘渗透率比裸316ss低约1-2个数量级，比裸Eurofer97和F82H马氏体钢的参考数据低约2-3个数量级。
Er2O3coating is formed on austenitic stainless steel 316ss by sol–gel method. The results showed good crystallization of coating by baking in high purity flowing-argon at 973K, and indicated that a little oxygen in baking atmosphere is necessary to crystallization of coating. The best baking temperature could be thought as 973K, to get good crystallization of coating and avoid strong oxidation of steel substrate. The deuterium permeation test was performed for coated and bare 316ss, to evaluate the property of Er2O3sol–gel coating as a potential tritium permeation barrier. In this study, the deuterium permeability of coated 316ss is about 1–2 orders of magnitude lower than that of bare 316ss, and is about 2–3 orders of magnitude than the referred data of bare Eurofer97 and F82H martensitic steel.
