摘要
模拟压水堆一回路加锌水环境,对镍基690合金在加锌浓度为10μg/kg的320℃,15.20 MPa溶液中进行了1000 h的腐蚀试验。采用XPS深度分析法对试样氧化膜进行分析。结果表明,锌能有效地降低690合金的均匀腐蚀速率,加锌后氧化膜形貌和成分都有了明显改变,氧化膜厚度变薄。
Zinc primary coolant addition of zinc, morphology and addition effects on general corrosion of Nickel- with 10 μg/kg zinc addition at 320 ℃, 15. 20 base Alloy 690 were investigated in simulated PWR MPa for 1000 h. The results show that with the ively reduced. The surface oxide film is thinner, the changed.
