在第四代国际论坛选择超临界水冷反应堆作为研究的六个概念之一后，对超临界水（SCW）中材料降解的兴趣显着增加。虽然现在存在大量关于SCW中合金腐蚀的文献，但大多数研究都集中在金属-水界面的金属侧。本文使用新数据和对SCW腐蚀的选择性审查，强调了SCW密度的变化如何改变腐蚀机制，并强调了SCW腐蚀与500°C以上高温蒸汽之间的密切联系。还讨论了测试方法中的关键问题。
Interest in materials degradation in supercritical water (SCW) increased significantly after the Generation IV International Forum selected the supercritical water-cooled reactor as one of six concepts for investigation. While a significant body of literature now exists on alloy corrosion in SCW, most studies have focused on the metal side of the metal–water interface. Using new data and a selective review of corrosion in SCW, this paper highlights how changes in SCW density change the corrosion mechanism, and highlights the close link between corrosion in SCW and high-temperature steam above 500°C. Key issues in test methodologies are also discussed.
