Weight loss and In Situ electrochemical measurements were used in an autoclave to study the corrosion behavior of UDC by adding corrosion inhibitor after immersion for a period (pre-corrosion).

At low pH, severe corrosion was observed, while higher pH led to passivation via nickel oxide and calcium carbonate formation. Microscopy and XPS analyses revealed pH-dependent changes in pit morphology and density. Under intermediate pH, localized redeposition of nickel was detected at pit centers, forming nanoscale features. Finite element simulations confirmed that pit geometry creates a chemical potential gradient driving inward metal flux.

Under these extreme conditions, water exhibits distinct physicochemical properties that significantly elevate the corrosion susceptibility of alloys. This study investigates the mechanisms of oxidative corrosion, electrochemical corrosion, and stress corrosion cracking (SCC) in alloys exposed to HTHP water. From a synergistic perspective, it elucidates how interconnected phenomena—namely, accelerated oxide layer rupture, enhanced ion diffusion, and localized stress concentration—markedly accelerate alloy degradation. The findings reveal that reduced intermolecular hydrogen bonding, increased electrical conductivity, and heightened activity of corrosive ions in HTHP water are critical drivers of corrosion. By analyzing molecular structures and dynamics, it clarifies the complex interplay among HTHP water properties, corrosive ions, electrochemical reactions, and mechanical stress, thereby enhancing the understanding of alloy failure mechanisms. These insights provide a theoretical basis for designing corrosion-resistant materials and equipment.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 10","pages":"1560-1571"},"PeriodicalIF":2.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145204843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
