The results demonstrated that sulfate-based stabilizers accelerated the formation of α-FeOOH, thereby enhancing the corrosion resistance of WS in simulated marine atmospheres. Particularly, the A1 stabilizer consisting of the CuSO4, FeSO4, NaHSO3, and Cr2(SO4)3 solution system shows better applicability under the simulated marine atmosphere.

How these methods compare in terms of quantitative and qualitative information is often unclear. In this study, we directly compare low-energy ion scattering spectroscopy (LEIS), secondary ion mass spectrometry (SIMS), and angle-resolved X-ray photoelectron spectroscopy (AR-XPS) depth profiling analyses. Therefore, we use the Zn–Al–Mg model coatings after alkaline and acidic treatments in model solutions. The combined use of AR-XPS and LEIS depth profiling proved effective in studying compositional and elemental changes in the surface oxides of Zn–Al–Mg coatings after alkaline and acidic treatments. Additionally, by combining these methods, SIMS depth profiling can be effectively calibrated for matrix effects. Here, we find that, for example, Mg is considerably more sensitive to SIMS detection, based on effective secondary ionisation.

The results indicate that the FeCr2O4/α-Fe interface primarily consists of Feme-Oox mixed ionic-covalent bonds and Feme-Feox metallic bonds, with the Feme-Oox bonds dominating the interfacial adhesion strength. Compared with the Fe2 top-site interface, the Fe1 and Cr top-site interfaces exhibit low charge accumulation and longer Feme-Oox bonds, which results in weaker Feme-Oox bonding strength at the interface. The orbital hybridization between Fe and O atoms at the Fe2 top-site interface is stronger than that at the Cr top-site interface, leading to greater structural stability for the Fe2 top-site interface.

This analysis allowed for the determination of the non-Faraday process contribution, thus clarifying its impact mechanism and the overall corrosion mechanism under dynamic DC interference. The findings indicate that non-Faraday processes play a crucial role in dynamic DC interference scenarios, with non-Faraday current increasing proportionally to the amplitude of the interference potential while Faraday efficiency remains unchanged.

Herein, in this work, a highly sensitive and stable Ag/AgCl electrode is proposed by employing a protective coating layer based on polypyrrole (PPy). Using a facile coating process, a uniform PPy layer is coated on the surface of an Ag piece, effectively precluding hydroxide ions from reacting with AgCl.

Three modifications of a test with the drying RH of 30%, 50% and 70% were carried out, and average and real-time corrosion rates, corrosion morphologies and composition of corrosion products were evaluated. The drying RH had a specific effect on the corrosion of each metal. The corrosion rate of carbon steel was the highest in the test with the highest drying RH while zinc and aluminium showed a decrease in corrosion rates with increasing drying RH. The mechanism of magnesium alloy corrosion was influenced by electrolyte distribution with the highest corrosion rate in the test with drying at 50% RH. Drying at 30% RH was found to provide the best correlation to the real-world performance of the metals.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 7","pages":"979-995"},"PeriodicalIF":1.6,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.202414777","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581993","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}
