The corrosion rates of carbon steel 1010 and zinc coupons at the buffer areas of ten stations and five cross passages along the NEL were monitored over a period of one year. The median temperatures were between 31 and 36°C while the median relative humidity varied between 43 and 53%. At all exposure sites, the values of relative humidity corresponding to the 75th percentile values were below 60%, with very few data points registering above 80%. The cross passages showed a lower degree of fluctuations in the temperature and relative humidity compared to the buffer areas. The corrosivity levels showed some differences between exposure sites, but their values were generally low and could be categorised as C1 according to the ISO 9223:2012 categorisation. A set of procedures for an accelerated laboratory test to approximate the corrosion in the tunnel was also studied. The test procedures involved the exposure to a salt fog containing 0.12% Na2SO4 + 0.05% NaCl, followed by a drying phase and subsequent exposure to a constant temperature of 40°C and a constant relative humidity of 60%. It was found that after exposure for 80 h, the accelerated tests were able to generate the degree of corrosion observed in the most severe conditions in the field.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"230 - 242"},"PeriodicalIF":1.8,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48909605","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}

Their surface morphology and corrosion resistance immersed in 3.5 wt-% NaCl solution are explored. Our results suggest that the double doping of [Demim]Br and SDBS will change the surface morphology of the coating and a uniform and dense film is observed in the double-doped MgAl-LDHs, which is denser than those of the two single-doped MgAl-LDHs coatings, thus providing a superior corrosion resistance. Such an improvement can be ascribed to the synergetic inhibition effect of [Demim]Br and SDBS against the corrosion of the Mg alloy substrate. More importantly, the charge transfer resistance of the sample coated with the double-doped MgAl-LDHs is still high after 3 d of immersion, benefiting from the excellent self-healing effect.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"259 - 269"},"PeriodicalIF":1.8,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46138892","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}

Inhibition efficiency decreases with temperature. The presence of 1-heptatriacotanol, the diterpene alcohols like phytol and 3, 7, 11, 15 tetramethyl-2-hexadecen-1-ol are identified as major constituents through GC-MS analysis of CIW. The electronic properties and inhibition efficiency of these compounds were evaluated using DFT and material studio software. The donor–acceptor type interactions resulting from the migration of lone pair of electrons of the ‘O’ atom of these molecules to the vacant ‘d’ orbital of the metal is evident from these calculations. The reduction in the double-layer capacitance with the incremental addition of CIW is noticed. CIW offers mixed inhibition with anodic predominance. CIW forms a multimolecular layer on the metal surface obeying the Temkin isotherm model. Surface perturbations were followed qualitatively by SEM, stereomicroscope and XPS.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"243 - 258"},"PeriodicalIF":1.8,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46541660","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}

And the reasons for the differences in corrosion resistance were investigated in terms of microstructure, electrochemical behaviour and oxide film. The results show that the two alloys exhibit different corrosion characteristics, with CoCrFeNi alloy displaying typical passivation characteristics and CoCrFeNiMn alloy exhibiting activation behaviour. The CoCrFeNi HEA with compact and protective passive film has lower corrosion current density, larger film resistance and polarisation resistance, meaning a lower corrosion rate and superior corrosion resistance compared with those of CoCrFeNiMn alloy. Moreover, CoCrFeNiMn alloy forms a discontinuous and loose corrosion product film with higher Mn content and lower contents of Cr, Fe and Co compared to the matrix, which decreases its protection performance. The addition of Mn changes the electrochemical behaviour, and higher Mn oxides/hydroxides within oxide film are unfavourable to forming a stable passive film.
