对高纯度 LiF-BeF2 (Flibe) 中的 SS304 和 SS316L 奥氏体钢在 500 和 600 摄氏度下进行了 1000 小时的静态腐蚀试验。暴露后，由于溶解在 Flibe 中的 HF 的氟化作用，钢表面被腐蚀。钢表面的晶界优先受到攻击。讨论了包括选择性晶间腐蚀在内的腐蚀机理。 SS304 和 SS316L 在 Flibe 中在 600 摄氏度下的腐蚀速率估计分别为 10.6 和 5.4 μm/年。 (c) 2009 Elsevier B.V. 保留所有权利。
Static corrosion tests for SS304 and SS316L austenitic steels in high purity LiF-BeF2 (Flibe) were carried out at 500 and 600 degrees C for 1000 h. After the exposure, the steel surfaces were corroded due to the fluoridation by HF dissolved in Flibe. The grain boundary of the steel surfaces was preferentially attacked. The mechanism of corrosion including selective intergranular attack was discussed. The corrosion rate of SS304 and SS316L in Flibe at 600 degrees C was estimated as 10.6 and 5.4 mu m/year, respectively. (c) 2009 Elsevier B.V. All rights reserved.
