The corrosion resistance of the Al–Al2O3-coated steel was investigated using potentiodynamic tests, electrochemical impedance spectroscopy tests and measurement of galvanic current density in a bimetallic cell. It was found that the anodic oxidation resulted in the formation of a porous Al2O3 coating on the surface of the Al-coated steel, improving both its corrosion resistance and galvanic corrosion resistance when coupled with carbon fiber reinforced nylon 6 composite (Cf/PA6). Silane treatment effectively sealed the pores within the Al2O3 coating, resulting in improved corrosion protection for Al–Al2O3-coated steel due to the exceptional insulation, impermeability and hydrophobic properties of silane coating. Compared to the Al-coated steel/carbon fiber reinforced polymer (CFRP) couple and Al–Al2O3-coated steel/CFRP couple, stable galvanic current density decreased by approximately 75% and 45%, respectively.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 1","pages":"87-98"},"PeriodicalIF":1.6,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180254","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}

Corrosion kinetics was studied by thermogravimetric analysis at 710°C for 100 h under three gas conditions. After isothermal exposure, the corroded coupons were characterized in detail by X-ray diffraction, scanning electron microscopy, an electron probe microanalyzer, and transmission electron microscopy. CO addition to wet CO2 resulted in lower oxygen partial pressure and lower oxide growth kinetics. It also suppressed iron-rich oxide nodule formation, as compared to the wet CO2 gas environment. A Cr-depletion zone was observed underneath the oxide scale in the substrate, but no obvious internal carburization was observed in all three gas environments. A thin, protective oxide scale consisting of an outer layer of a Cr-rich spinel and an inner Cr-rich chromia layer was developed in CO-containing gas conditions, with or without SO2. The effect of CO on oxidation and scale formation is discussed in comparison with that in wet CO2 conditions.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"75 12","pages":"1652-1660"},"PeriodicalIF":1.6,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.202414312","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141869950","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}

An analysis of the environment around the excavated artefacts is presented, followed by geochemical modelling of the likely corrosion products and subsequent comparison with real phases in the corrosion layer estimated by X-ray diffraction. A total of 16 archaeological sites with fine clay soils and the potential for long-term flooding were evaluated. Although the soil pore solution contained high levels of silicates, no such phases with iron in the corrosion products were confirmed. Carbonate corrosion products, typical of bentonite environments, were also not observed. Although oxygen access is very limited in the environments of all sites, even low concentrations shifted the equilibrium of corrosion products formed in favour of (hydroxy)oxides.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 1","pages":"137-154"},"PeriodicalIF":1.6,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141784166","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 composition of the TCP solution was as follows: 45 g/L Cr(NO3)3, 14 g/L CoCl2, 1.3 g/L NiCl2, 10 g/L citric acid, 10 g/L succinic acid and 1 g/L sodium dodecyl sulphate. The properties of TCP were characterised by a range of techniques, including macroscopic observations, scanning electron microscope, energy-dispersive X-ray spectrometer, three-dimensional (3D) morphometry, electrochemical impedance spectroscopy, polarisation curves and conductivity tests. The TCP prepared in this experiment exhibits a uniform black colour and bright appearance, predominantly composed of Zn, Ni, O, Cr and Co. The TCP enhances the impedance of Zn–Ni alloys, reduces the corrosion current to 1.99 × 10−5 A/cm2 and maintains a flatter surface 3D morphology and less surface roughness following electrochemical testing. It has better corrosion resistance. Following the preparation of the TCP on a suitably sized shell sample, the shell resistance was 1.2 mVDC with good electrical conductivity, which meets the requirements for electrical connector applications.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"75 11","pages":"1463-1471"},"PeriodicalIF":1.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141743157","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}
