The bidirectional regulation of Ta content on oxidation at 800°C and corrosion in 3.5 wt% NaCl solution was systematically investigated. Increasing Ta degrades oxidation resistance with higher mass gain, parabolic rate constant Kp, and thicker oxide layers, owing to the deteriorated oxide structure, diluted Cr-based protective film, and accelerated ionic diffusion through the Laves phase. Conversely, Ta markedly improves corrosion resistance by raising the corrosion potential and reducing the corrosion current density, due to the formation of a dense Ta2O5 passive film, which repairs structural defects and resists the attack of chloride ions.

Analytical models were developed to simulate the ER sensor response to various geometries of localized attacks. These theoretical predictions were validated against experimental data, including controlled electrochemical dissolution and realistic sodium chloride exposure. The comparison revealed a strong correlation between the models and experimental measurements, highlighting a critical limitation of the resistometric method: ER sensors severely underestimate the actual depth of localized attacks. Specifically, models demonstrate that for a localized attack covering less than 5% of the sensor's measuring area, a defect consuming 80% of the initial thickness yields an apparent overall sensor reading of merely 20% thickness loss. Furthermore, under practical NaCl exposure scenarios, actual pit depths reaching 50 µm resulted in sensor readings of only 11 µm. These findings are essential for the accurate interpretation of ER sensor data and the implementation of appropriate safety margins in industrial applications.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 10","pages":"1653-1661"},"PeriodicalIF":2.1,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70188","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100240","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}

Specimens tested in ambient conditions under tensile loading showed several thousand microcracks per mm2, with maximum length in the range of 15–20 µm and maximum depth of about 3 µm. Increasing plastic deformation resulted in a larger number of microcracks. While specimens tested in water with 80 mg/L sulfide showed a much smaller microcrack density, with no indication of growth due to the presence of sulfides. Tensile testing of three different batches of Cu-OFP material showed similar results, suggesting that the results are batch-independent. These results indicate that surface microcracks form on Cu-OFP due to plastic straining both in air and in sulfide-containing water. Furthermore, this study demonstrates that, under the tested conditions, sulfide exposure does not promote microcrack propagation through stress corrosion cracking.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 10","pages":"1644-1652"},"PeriodicalIF":2.1,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70187","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100239","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}

To study the effect of fluence on corrosion resistance, implantation was performed at three fluence rates, with the highest fluence (3 × 1017 ions/cm2) showing the best corrosion resistance.

This study examines the effect of oxygen (O2) and nitrogen oxide (NO) gas concentrations on solar salt thermal stability and 310N stainless steel corrosion at 600°C up to 1224 h. The impact of the gas atmosphere (5–80 vol% O2, 400–600 ppm NO) on salt chemistry, including nitrate, nitrite, oxide, and chromate ions, was analyzed, and corrosion behavior was evaluated through weight change, corrosion rate, and microstructural analysis. The results show that introducing NO gas concentrations ≥ 400 ppm with at least 5 vol% O2 stabilizes salt decomposition by controlling nitrite and oxide ion formation and promotes the development of a protective corrosion layer on the steel surface. Once this protective layer is formed, variations in oxygen concentration (5–80 vol%) in the presence of ≥ 400 ppm NO gas have a minimal long-term effect on the corrosion behavior of stainless steel in solar salt. These findings underscore the importance of maintaining minimum O2 and NO levels to optimize salt chemistry that effectively mitigates steel corrosion in solar salt systems.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 9","pages":"1579-1594"},"PeriodicalIF":2.1,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148872011","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}
