| 摘 要： | 通过模拟压水堆一回路水环境,对316L奥氏体不锈钢在320℃含锌10μg/kg的高温溶液中进行了1000 h的腐蚀实验,对腐蚀后的试样表面进行了XPS分析。结果表明,试样在含锌溶液中形成了化学成分为(Zn,Fe,Ni)(Cr,Fe)2O4的致密氧化膜,随着腐蚀时间的增加,氧化膜中的富Cr区由内层扩展至整个氧化膜。 |

| Abstract: | The effect of Zn addition on the composition of oxide scales formed on 316L stainless steel has been studied in high-temperature and high pressured waters, which aim to simulate the primary loop water environment of pressurized water reactor (PWR). Then, the formed oxide scales on the steel are analyzed by X-ray photoelectron spectroscopy (XPS). The results show that after soaked in water with 10 μg/kg Zn addition at 320 ℃ for 1000 h, compact oxide scales formed on the steel, which consist mainly of (Zn, Fe, Ni)(Cr, Fe)2O4, with an inner portion rich in Cr. However, the Cr rich portion extends gradually outwards to lead the whole oxide scale to become the same with the increasing exposed time. |
