The increased thickness improves compatibility with industrial materials, while the additional tracks provide a more qualitative assessment of non-uniform corrosion. The probe's performance was evaluated under submerged exposure in natural seawater and across anodic to cathodic potentials, simulating galvanic couplings and varying levels of cathodic protection. Its monitoring results were benchmarked against conventional weight-loss coupons, and the effect of corrosion product accumulation on probe functionality was examined. The probe delivered accurate corrosion rates and confirmed its reliability in natural seawater. The increased thickness extended service life and provided a corrosion-depth sensitivity of 70 nm, while the greater number of tracks brought the exposed area closer to that of coupons, improving detection of non-uniform corrosion. The probe also detected, in real time, variations in corrosion rate caused by interruptions in the cathodic protection system.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 7","pages":"1145-1158"},"PeriodicalIF":2.1,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cathodic protection (CP) is commonly used to prevent corrosion, but long-term monitoring is limited by intrusive methods. This study evaluates electrochemical impedance spectroscopy (EIS) to track corrosion product formation on steel exposed to a soil-mimicking solution under CP. The steel was immersed for 15 days, with CP applied for 11 days, and EIS measurements recorded periodically. Voltammetric measurements showed that CP reduced the corrosion rate from 410 to 7 µm yr⁻¹ between days 5 and 15. EIS results indicate that, under open circuit conditions, the electrochemical response is consistent with mixed activation–diffusion behavior, whereas under CP the impedance response becomes dominated by activation and interfacial film effects within the measured frequency range. This shift is associated with substantial modification of the interfacial environment and the development of a more resistive surface film. X-ray diffraction identified the formation of calcareous deposits, primarily aragonite and brucite, together with iron oxide corrosion products.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 7","pages":"1159-1166"},"PeriodicalIF":2.1,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70137","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these relationships, various electrochemical characterization methods (electrochemical potentiodynamic reactivation, critical pitting potentials, and corrosive gel electrolytes) were employed. These methods correlate the often pronounced susceptibility of martensitic stainless steels to pitting corrosion with the presence of chromium-depleted regions and link these features to the underlying heat treatment parameters. In order to determine optimal heat treatment conditions from a corrosion-resistance perspective, the austenitization temperature, austenitization time, cooling rate, sub-zero treatment, and tempering temperature were investigated within technologically relevant ranges. The focus was placed on heat treatment combinations that promote chromium depletion, with the aim of avoiding such conditions.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 7","pages":"1094-1105"},"PeriodicalIF":2.1,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70135","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148522817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under oxidation process (850°C/5 h) of low-temperature step of the two-step process, a continuous Al2O3 film forms on ground surface of AFA alloy, whereas a Cr2O3 film develops on polished AFA alloy surfaces. The mechanism of forming Al2O3 film on ground surface has been clarified. In addition, the high-temperature step of the two-step process critically promotes the growth of the protective Al2O3 film. When the oxidation temperature is excessively high (1100°C), it causes wrinkled Al2O3 film morphology, leading to film cracking and spallation. Conversely, insufficient oxidation temperature (900°C) leads to incomplete film coverage due to inadequate growth of the Al2O3 film.
