Abstract

Abstract The corrosion behavior of GH3535 alloys in KCl–MgCl2 eutectic salts with or without magnesium (Mg) was investigated using the static immersion tests. The effect of purification treatment on the corrosion of GH3535 specimens was also evaluated by the different analysis. The KCl–MgCl2 salts purified with Mg and reducing service temperature can slow down the corrosion rate of GH3535 specimens. Infrared spectra results showed that purification treatment reduced the content of crystal water in the KCl–MgCl2 salts. The difference of hydrate content in KCl–MgCl2 salts and the diffusion rate of Cr in alloy are the main reasons for the change of GH3535 specimens corrosion rate.

GH3535合金在镁净化KCl–MgCl2共晶盐中的腐蚀行为

摘要:采用静态浸渍试验研究了GH3535合金在含镁和不含镁的KCl-MgCl2共晶盐中的腐蚀行为。通过不同的分析，评价了净化处理对GH3535试样腐蚀的影响。Mg净化后的KCl-MgCl2盐和降低使用温度可以减缓GH3535试样的腐蚀速率。红外光谱结果表明，净化处理降低了KCl-MgCl2盐中结晶水的含量。KCl-MgCl2盐中水合物含量的差异和Cr在合金中的扩散速率是GH3535试样腐蚀速率变化的主要原因。
