通过电化学极化实验对TP317和HAL77-2在造纸中水中进行腐蚀性能研究，对比这两种材料的耐腐蚀性，提出在新建的600 MW热电联产机组的凝汽器选材依据。实验结果表明，在造纸中水中，TP317比HAL77-2更耐腐蚀；在加入NaCl质量分数高于4％的条件下，TP317在中水的耐腐性急剧下降。

Experiments on corrosion of TP317 and HAL77-2 immersed in papermaking intermediate water were conducted via the electrochemical method .After comparing the corrosion resistance of the two mate-rials, it advanced the material-choosing principle for the condenser of a new 600MW plant with the com-bination of heat and power .The experimental results show that in recycled water TP 317 has higher corro-sion resistance than HAL77-2.However, when more than 4%NaCl is added to the intermediate water , the corrosion resistance of TP 317 decreases dramatically .
