The coating exhibited excellent corrosion resistance with a low corrosion current density of 2.918 × 10^-7A/cm², which was two orders of magnitude lower than that of the Q345 steel substrate, and a protection efficiency of 98.22%. It remained superhydrophobic after 120 h of immersion in 3.5 wt.% NaCl solution and maintained a contact angle &gt; 150° in the pH=2 ~ 13 range. In addition, the coating showed excellent mechanical stability with a contact angle of &gt; 150° after 200 cm of sandpaper abrasion and a contact angle of 151.2° after 45 tape stripping cycles. The coating is both self-cleaning and photocatalytic, with a degradation rate of 30.24% for rhodamine B in 3 h and 21.78% after six cycles.

While the corrosion resistance of 316 L relies on the formation of a chromium-rich passive oxide layer, industrial conditions may expose the steel to various chromium species. Due to their hygroscopic nature, chromium salts can absorb moisture and form persistent thin electrolyte films on metal surfaces, creating aggressive microenvironments that promote localized corrosion. Despite their potential impact, the formation, stability, and corrosive effects of such deposits remain poorly documented. This review highlights the role of hygroscopic chromium salts in destabilizing the passive film of 316 L and increasing susceptibility to pitting and stress corrosion cracking in chloride media, emphasizing the need for further investigation to better assess corrosion risks in industrial environments.</p>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 9","pages":"1424-1437"},"PeriodicalIF":2.1,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.70164","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148872100","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 study focused on X80 pipeline steel and investigated the influence of two typical parameters—soil moisture content (10%, 20%, and 30%) and soil particle size (100, 500, and 1000 μm) on X80 steel corrosion behavior. Electrochemical testing, corrosion weight loss analysis, and morphological analysis were employed to investigate the relationship between varying corrosion patterns and soil conditions. The results demonstrate a strong positive correlation between soil moisture content and the corrosion rate of X80 steel. The corrosion rate of X80 steel showed a strong positive correlation with soil moisture content. This trend is primarily due to the role of water in enhancing the continuity and ionic conductivity of the soil electrolyte, which facilitates charge transfer and accelerates anodic dissolution. Electrochemical analysis revealed that under high moisture conditions, the film resistance (<i>R</i>_f) of corrosion products decreased significantly, indicating increased corrosion current and accelerated corrosion rates. In contrast, larger soil particle sizes inhibited corrosion progression. Coarse-grained soil (1000 μm), characterized by higher porosity, impeded the transport of water and oxygen, leading to increased (<i>R</i>_f) and charge transfer resistance. This resulted in fewer pits and shallower corrosion depths. Cathodic protection potential also significantly influences corrosion behavior. A potential of −1.2 V_SCE more effectively suppresses corrosion than −1.1 V_SCE. This study clarifies the interactions among dynamic stray currents, soil media, and cathodic protection, offering theoretical and practical insights for corrosion risk assessment and protection for buried pipelines near subway systems.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 9","pages":"1450-1470"},"PeriodicalIF":2.1,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148872099","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}

The results showed that 13Cr had a higher general corrosion tendency in the CO₂-saturated solution than in the other two environments. However, the passive film formed under the CO₂-saturated condition, although thinner, was more compact and contained fewer ionic defects, resulting in stronger re-passivation ability and lower local corrosion sensitivity. Surface analysis further indicated a higher Cr₂O₃ content in this film, which improved its compactness, reduced defect density, and enhanced self-healing ability.

The investigation systematically explored the influence of WC particle dosage in the plating bath and magnetic field intensity upon the surface topography, grain refinement, microhardness, and anti-corrosion performance of the coatings. The experimental findings demonstrated that appropriately selected WC concentration and magnetic field intensity could synergistically enhance the overall performance of the coatings. With a WC concentration of 10 g/L and a magnetic field intensity of 0.4 T, the resulting coating exhibited the highest WC co-deposition efficiency, with grains refined to approximately 13.7 nm and a smooth, compact, and defect-free surface morphology.

Reinforced concrete specimens are subjected to three-point bending to generate a load-induced crack. Steel coupons embedded in the concrete are electrically connected to the reinforcing steel to measure the macro cell corrosion current when an anodic site forms. Once the critical load for concrete cracking is exceeded, a macro cell corrosion current is recorded as soon as the load increases, indicating rupture of the passive film and, consequently, anodic activity at the crack location, associated with the formation of a new passive film that heals the passive film fracture. The elongation threshold is close to 950 microstrain (or 190 MPa). As soon as the load stops increasing, the corrosion current sharply decreases, suggesting rapid repair of the passive film.
