Few studies have focused on hot-corrosion resistance of Hf-doped NiAl alloys, and the sensitivity to Hf content needs further research. In this study, we prepare five types of NiAl alloy samples (0, 0.1, 0.3, 0.5, 1.0 at% Hf), with a NiAl-Ni<sub>2</sub>AlHf dual-phase structure. First-principles calculations and experimental observations reveal that the Ni<sub>2</sub>AlHf content directly affects the service performance of the NiAl alloy. Compared to the NiAl phase, Ni<sub>2</sub>AlHf exhibits greater ability to adsorb environmental media (O, S, and Cl). It also exhibits surface stress differences with NiAl, both of which lead to poor oxide adhesion and nucleation of HfO<sub>2</sub> particles during short-term hot corrosion. The thermodynamic formation energy and kinetic diffusion barriers of O and S at the NiAl/Ni<sub>2</sub>AlHf interface determine their interfacial segregation tendency. The interfacial accumulation behavior of O and S leads to severe internal oxidation and sulfidation, inhibiting the formation of protective oxide scales. Introducing 0.1 at% Hf is determined to be the most optimal for achieving balanced enhancement of the oxidation and corrosion resistance of the NiAl phase, providing a foundation for the design of NiAl-based alloys/coatings.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"258 ","pages":"Article 113404"},"PeriodicalIF":7.4,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145263754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The post-corrosion tested 316 L SS microloop sections were characterized with microscopy techniques to determine the microstructural and microchemical changes that occurred at the alloy/salt interface. It was found that 316 L SS showed heterogeneous dissolution at the hot-leg, whereas deposition of corrosion products occurred at the cold-leg. For the first time, experimentally obtained molten salt flow-induced corrosion of 316 L SS results were combined with computational thermodynamic-kinetic models to validate the dissolution and deposition in terms of elemental compositional changes at the alloy/salt interface. The thermodynamic-kinetic modeling predicted that the heterogeneous dissolution of Cr and Fe from the hot-leg section of 316 L SS persisted throughout the salt circulation. The model also estimated that, despite Cr deposition starting earlier than Fe, the total redeposition of Fe is expected to be significantly greater than that of Cr over the circulation of salt. Furthermore, the modeling accurately predicted the subsurface enrichment of Mo which is attributed to the reduced Cr activity and the relatively higher diffusion rate of Mo within the alloy matrix. The agreement between modeling and experimental results confirms that Fe chlorides dissolve at the hot-leg and subsequently deposit at the cold-leg due to activity changes driven by the thermal gradient. By contrast, Cr was not detected in the cold-leg deposits, which is attributed to its weaker temperature dependence on activity, limiting its redeposition under these conditions.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"258 ","pages":"Article 113383"},"PeriodicalIF":7.4,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145264112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
