Early detection of a low-quality coating or its improper application is crucial to prevent malfunctions, wear, corrosion, hydrogen diffusion, and the need for frequent reapplications. Here, we report a non-destructive test to assess key performance parameters of functional ceramic coatings, specifically those based on aluminum. The primary focus is on evaluating the electrical insulation and complex barrier efficiency of the whole coating system. A novel approach based on non-invasive electrochemical impedance spectroscopy (EIS) in the NO-Contact-to-the-Substrate setup (NOCS) is deployed to assess the barrier efficiency of the final coating system. The developed sensing performance can detect defects, pores and other inhomogeneities of the ceramic coatings and assess quality between five various levels (poor, semi-poor, medium, high, and very high).</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 7","pages":"1167-1176"},"PeriodicalIF":2.1,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148532796","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}

This review categorizes mechanisms into chemical, electrochemical, and mechanical modes. Chemical corrosion varies by environment: nitrate salts enable protective oxide films (e.g., Cr₂O₃, FeCr₂O₄) on Cr-steels, while chloride systems require Ni-based alloys with high Mo/W and strict impurity control to suppress Cr volatilization. Electrochemical corrosion is impurity-driven in chlorides (H₂O/O₂/Cl⁻ causing film breakdown and acidification) but milder in nitrates. Notably, welded joints are vulnerable; microstructural inhomogeneity induces galvanic cells, accelerating Heat-Affected Zone (HAZ) erosion. Mechanical corrosion involves flow delamination, thermal flaking, and stress-corrosion, where initial Cr diffusion eventually promotes intergranular cracking. Since static testing underestimates synergistic effects, future research must prioritize dynamic coupled testing and multiscale modeling to ensure high-temperature reliability.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"77 7","pages":"1125-1144"},"PeriodicalIF":2.1,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534408","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}
