Cl^-和S^(2-)对T23超临界水冷壁管侵蚀性的比较

Comparison of Cl^- and S^(2-) erosion on T23 material of supercritical water wall tube

本文通过电化学测试方法对T23材料在弱碱性Cl-和S2-溶液介质中腐蚀行为进行了探究。比较发现:低温弱碱条件下,高浓度的Cl-和S2-溶液介质中,Cl-对T23材料的侵蚀作用较强,而低浓度的Cl-和S2-溶液介质中,S2-对T23材料的侵蚀作用较强。

In this paper the corrosion hebavior of T23 material was studied in weak alkaline Cl-and S2-solution through the electrochemical method of test.It showed that the erosion of Cl-was stronger than S2-for high concentration of Cl-and S2-in the low-temperature weak alkaline condition.In addition,for low concentration condition the erosion of S2-was stronger.
