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，1000 h后其表面氧化膜依然完整致密，而经QPQ的试样腐蚀严重。

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 .T he 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 .
