| 摘 要： | 本文研究了F/M钢在超临界水（SCW）环境中的腐蚀性能。实验结果表明，F/M钢在SCW中的抗腐蚀性能较差，温度、溶氧浓度以及材料中的Cr含量对其腐蚀性能有较大影响。对12Cr表面进行盐浴复合处理（QPQ）、电镀Cr和磁控溅射Cr处理，以研究其对F/M钢在SCW中抗腐蚀性能的影响。研究表明，经电镀Cr和磁控溅射Cr处理的12Cr试样在SCW中具有优良的抗腐蚀性能，尤其是经磁控溅射Cr处理的试样，1 000 h后其表面氧化膜依然完整致密，而经QPQ的试样腐蚀严重。

| Abstract: | The corrosion performance of F/M steel in supercritical water (SCW) was studied. The results of general corrosion tests show that the corrosion performance of F/M steel in SCW is very bad. The temperature, concentration of oxygen and Cr have significant effects on the corrosion performance of F/M steel. The study of the effect of QPQ, electroplating Cr, and magnetron sputtering Cr on the corrosion performance of F/M steel in SCW shows that 12Cr with magnetron sputtering Cr and electroplating Cr has excellent corrosion performance, in particular that the oxide film of sample processed with electroplating Cr remains completing and compacting after 1 000 h while the one with QPQ experiences severe corrosion. |
