在自行搭建的高温高压水循环回路系统中, 通过原位电化学测量, 结合SEM观察和XPS分析, 研究了核级商用690合金和800合金在模拟压水堆核电站一回路高温高压水环境中的腐蚀行为. 结果表明, 690合金和800合金的自腐蚀电位随浸泡时间的延长而逐渐降低, 浸泡时间对690合金和800合金的阻抗谱影响并不明显. 经过408 h浸泡后, 690合金表面生成了大量针状氧化物,800合金表面则同时生成了针状氧化物和颗粒状氧化物. 690合金表面富Cr氧化层位于表面膜内侧, 而800合金的富Cr氧化层位于表面膜外侧. 在高温高压水中,690合金比800合金表现出更为优异的抗腐蚀能力. 浸泡实验后, 溶液中主要金属离子Ni2+,Cr3+和Fe3+的含量分别为0.1×10-6,0.1×10-6和0.3×10-6.
