摘要:
采用动电位极化、电化学阻抗谱(EIS)和80 ℃水溶液动态浸泡试验研究了Incoloy825合金在不同F-浓度的酸性高氯介质中的腐蚀行为。结果表明:Incoloy825合金在酸性高氯介质中的腐蚀行为受F-浓度的影响,随着F-浓度由0.1 g/L增至0.3 g/L,Incoloy825在酸性高氯介质中的腐蚀倾向减小、腐蚀速率降低。在含F-的酸性高氯介质中,Incoloy825合金表面的钝化膜稳定且致密,仍保持较好的耐腐蚀性能。Incoloy825合金在80 ℃的含F-酸性高氯介质中浸泡840 h后,其表面少数区域发生了点蚀,部分蚀坑的直径超过20 μm,点蚀深度超过10 μm。随着F-浓度在0.1~0.3 g/L范围内升高,Incoloy825表面的蚀坑直径有所增大,平均点蚀深度有所增加。
Abstract:
The corrosion behavior of Incoloy825 alloy in acidic high chloride solution with different F- concentrations were studied by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and dynamic immersion experiments at 80 ℃. The results show that the corrosion behavior of Incoloy825 alloy in acidic high chloride solution was affected by the F- concentration. As the F- concentration increased from 0.1 g/L to 0.3 g/L, the corrosion tendency and corrosion rate of Incoloy825 decreased in acidic high chloride solution. In the acidic high chloride solution containing F-, the passivation film on the surface of Incoloy825 alloy was stable and dense, and still maintained good corrosion resistance. After the Incoloy825 alloy was immersed in the acidic high chloride solution containing F- at 80 ℃ for 840 h, pitting corrosion occurred in a few areas. The diameter of some corrosion pits was more than 20 μm and the depth was more than 10 μm. With the increase of F- concentration in the range of 0.1~0.3 g/L, the pits diameter and the average pits depth on the surface of Incoloy825 increased.
