超临界机组的腐蚀与防护

Corrosion and Anti-corrosion in Super-critical Water Power Plant

综述超临界机组的腐蚀,包括不同制造材料,如奥氏体不锈钢、马氏体不锈钢、镍基合金、钛基合金等在超临界水中的腐蚀行为与机理。探讨腐蚀的机理与水工况之间的联系。在此基础上,综述超临界机组中,为防止腐蚀所采用的水化学调控与加药策略,以及在化学加药和腐蚀防护上的最新研究进展。

The corrosion behavior and the corrosive reaction mechanism in super-critical water for various materials, such as Austenitic steels, Martensitic steels, Nikel-alloy and Ti-alloy,were reviewed. The correlation between corrosion and parameters o{ the water was discussed in detail. Furthermore, the recent strategy adopted for anti-corrosion by adjusting the water parameters with various additives was also introduced.
