摘要: 

采用磁控溅射技术在高温合金N5表面制备与其化学成分相同的纳米晶涂层,并添加0.5% (质量分数) Y对涂层进行成分调控,研究其在850 ℃、75%Na2SO4 + 25%K2SO4和900 ℃、75%Na2SO4 + 25%NaCl (均为质量分数)两种熔盐环境下的短期热腐蚀行为。结果表明,N5合金在两种熔盐下均表现出较差的耐腐蚀性。纳米晶涂层在熔融硫酸盐中表现出优异的耐腐蚀性能,但在含NaCl环境中对耐腐蚀性能的提升并不明显。腐蚀5 h后,涂层表面氧化膜剥落,涂层发生内腐蚀。添加活性元素Y未对其在含NaCl环境中的耐蚀性能起到有效改善作用,进一步对纳米晶涂层在1000 ℃预氧化20 h能显著提高其耐腐蚀性能,一定厚度的预制氧化膜能有效阻挡熔盐渗透,降低腐蚀速率。

Abstract

The nanocrystalline coatings of Ni-based single crystal superalloy N5 with and without addition of 0.5%(mass fraction) Y were prepared on the superalloy N5 by magnetron sputtering technology, and then their short-term hot corrosion behavior was studied beneath deposit films of 75%Na2SO4 + 25% K2SO4 at 850 oC, and 75%Na2SO4 + 25%NaCl (in mass fraction) at 900 oC in air. The results showed that the bare N5 exhibited poor corrosion resistance. Although, the N5 alloy with nanocrystalline coatings showed excellent corrosion resistance to the mixed salts, but, the enhanced corrosion resistance to the NaCl containing salts was not obvious for the N5 nanocrystalline coating and the Y-modified ones. Besides, scale spallation and internal corrosion occurred for the coatings after 5 h corrosion test. The corrosion resistance of nanocrystalline coatings can be significantly improved by proper pre-oxidation at 1000 oC for 20 h, the pre-formed oxide scale was able to suppress the attack of the molten salts to certain extent and thus delay the corrosion.
