The results show that the oxidation kinetics of 37Fe and 42Fe alloys at 650°C and 700°C both conform to the parabolic rule, the outer Ni–Fe spinel and the inner Cr2O3 are formed after oxidized for 1000 h, also accompanied by the internal oxidation of Al. The protective oxides containing external Cr2O3 and internal Al2O3 were obtained faster and more by the acceleration of Cr diffusion rate, which made the alloys have excellent steam oxidation resistance at 700°C. The 47Fe alloy loses mass after oxidation at 650°C for 60 h due to the formed iron oxides are easy to peel off at the initial oxidation stage, but follow the parabolic rule of stable oxidation at 700°C.

Although all grinding belts produced comparable ground surfaces, differences in corrosion resistance were detected. The cause of the local corrosion susceptibility was identified and quantified using electrochemical and surface analytical methods. During grinding with granular abrasive belts, steel particles are generated, which become highly heated through friction in the grinding process and consequently fuse locally with the steel surface. These resulting particles form defects in the ground surface with critical crevice geometries, preventing the formation of the protective passive layer. These surface defects were identified as the starting points of local corrosion processes. The critical defects occur particularly when using the so-called granular abrasive belts and are attributed to their special surface topography, which causes significant localization of the grinding processes. A higher corrosion resistance was achieved with single-layered abrasive belts that have a more uniform topography.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 7","pages":"912-924"},"PeriodicalIF":1.6,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.202414733","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582453","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 proposes an effective strategy to enhance the corrosion resistance of the FMAN alloy in a neutral solution without loss of superelasticity via Ta-doping. The slightly improved corrosion resistance in 3.5 wt% NaCl solution is attributed to the coupling effect of the Ta-rich austenite and Ta-rich precipitates with a low corrosion rate. In situ Raman results demonstrated that Ta promotes the rapid formation of uniform Al oxyhydroxide (Al(OH)3), which protects the substrate in synergy with a Ta2O5 oxide film at the initial corrosion. Atomic-scan Kelvin probe force microscopic results demonstrated that corrosion production film including Ta2O5 oxide reduces the potential difference (from ~41 to ~16 mV) between the matrix and the Ta-rich phase, weakening the micro-cell corrosion.</div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 7","pages":"1019-1027"},"PeriodicalIF":1.6,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582436","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}
