摘要:

以压水堆一回路系统紧固件常用42CrMoE低合金钢材料为研究对象，采用电化学测试和浸泡实验研究了温度对其在硼酸溶液中腐蚀行为的影响。结果表明，温度升高促进了42CrMoE钢在硼酸溶液中的阳极溶解和阴极反应过程，导致其耐蚀性下降。其腐蚀类型从低温时的均匀腐蚀逐渐演变为高温时的局部点蚀为主。42CrMoE钢的腐蚀速率随温度升高显著增大，这是由加速硼酸介质的腐蚀过程和降低腐蚀产物的稳定性共同作用导致的。此外，随浸泡周期的延长，其腐蚀速率呈现先减小后增大，97.5℃时腐蚀速率可达到1.3 mm/a。

关键词 ：温度, 42CrMoE低合金钢, 硼酸, 腐蚀, 点蚀

Abstract：

Effect of temperature on the corrosion behavior of 42CrMoE low alloy steel in boric acid solution was investigated using electrochemical measurements and immersion tests, taking 42CrMoE steel for fasteners of pressurized water reactor (PWR) primary system as the research object. The results showed that the increase in temperature promotes the anodic dissolution and cathodic reaction process of 42CrMoE steel in boric acid solution, resulting in a decrease in its corrosion resistance. Its corrosion type gradually evolved from uniform corrosion at low temperature to local pitting corrosion at high temperature. Moreover, the corrosion rate of 42CrMoE steel increases significantly with the increase of temperature, which is caused by accelerating the corrosion process of boric acid medium and reducing the stability of corrosion products. In addition, the corrosion rate first decreases and then increases with the elongation of the immersion cycle, and the corrosion rate can reach 1.3 mm/a at 97.5^oC.

Key words： temperature 42CrMoE low alloy steel boric acid corrosion pitting
