摘要

DSM11镍基高温合金表面制备Al-Si、Al和Co-Al三种涂层，研究三种涂层在900℃下的涂盐（质量分数为5% NaCl+95% Na2SO4）热腐蚀性能和800℃下的疲劳性能。实验结果表明：在900℃热腐蚀200h后，Al-Si涂层和Co-Al涂层表面腐蚀区均形成了以Al2O3为主的连续且致密的氧化层，抑制热腐蚀反应的进行，具有一定的抗热腐蚀性能；Al涂层表面腐蚀区形成了混合型氧化层，热腐蚀反应会持续进行，抗热腐蚀性能较差。在800℃的疲劳实验后，Al-Si涂层表面生成大量的微裂纹，涂层容易发生开裂，进而引起合金试样快速断裂；Co-Al涂层和Al涂层的合金试样表现较好的抗高温疲劳性能。在高温合金的防护涂层使用中，要充分考虑到涂层的服役环境，对相关性能进行综合评价，选出最适合的防护涂层。

Abstract

Three coatings (Al-Si coating

Al coating and Co-Al coating) were prepared on the surface of nickel-based superalloy DSM11. The hot corrosion behaviors in the salt of 5%NaCl+95%Na2SO4 (mass fraction) at 900℃ and the fatigue property at 800℃ were investigated. The coatings after corrosion for 200h at 900℃

Al-Si and Co-Al coatings had excellent hot corrosion resistance to further hot corrosion because of a continuous and dense Al2O3 protective layer on the surface. Al coating had poorer hot corrosion resistance for a mixed oxidation layer in the corrosion area

which could not prevent hot corrosion. After fatigue test of the coatings at 800℃

the alloy samples were prone to rapid fracture that a lot of micro cracks appeared on the surface of Al coating. Co-Al and Al coatings showed better high-temperature fatigue performance. In order to select the most suitable protective coating of nickel-based superalloy

service environment and integrated performance should be fully considered.
