摘要
采用高压釜腐蚀试验研究Zr-Sn-Nb合金在模拟压水堆一回路注锌水化学环境中的腐蚀行为,对Zr-Sn-Nb合金在无锌和加锌水化学环境中的腐蚀增重、氧化膜形貌等现象进行分析。结果表明:Zr-Sn-Nb合金在无锌和加锌水化学环境中腐蚀150 d时腐蚀增重曲线发生转折,加锌对Zr-Sn-Nb合金腐蚀增重量、腐蚀动力学规律、氧化膜形貌、氧化膜物相、氧化膜厚度、氢化物分布和吸氢浓度无明显影响。
The corrosion behavior of Zr-Sn-Nb in the simulated PWR primary circuit zinc-injected aqueous chemical environment was investigated by autoclave corrosion test to analyze the surrosion and oxide film morphology of Zr-Sn-Nb alloy in zinc-free and zinc-added aqueous chemical environment.The results show that the surrosion curve of Zr-Sn-Nb alloy turns when it is corroded in zinc-free and zinc-added aqueous chemical environment for 150 days.Zinc addition has no significant effect on the surrosion,corrosion kinetics law,oxide film morphology,oxide film phase,oxide film thickness,hydride distribution and hydrogen absorption concentration of Zr-Sn-Nb alloy.
