The microstructure and phases of the obtained coating were analysed using an ultra-depth-of-field microscope and X-ray diffraction, respectively. The electrochemical corrosion properties of CoCrFeNiMo HEA coating in 3.5% NaCl, 0.1 M H2SO4 and 0.1 M NaOH solutions were comparatively evaluated using an electrochemical workstation, and the corrosion mechanisms were also discussed by the corrosion models. The results show that the CoCrFeNiMo HEA coating is mainly a solid solution structure of face-centered cubic, which forms mechanical bonding at the coating interface. The charge transfer resistance R ct of 597 × 1016 μA·cm–2 in 0.1 M H2SO4 solution is the highest and the corrosion current density i corr of 4.203 × 10–7 μA·cm–2 also presents the lowest among the three kinds of corrosive solutions, which shows the highest electrochemical corrosion resistance. As a result, the sequence of corrosion resistance is in 0.1 M H2SO4 solution > in 3.5% NaCl solution > in 0.1 M NaOH solution, in which the corrosion resistance is further improved by the passive film on the CoCrFeNiMo HEA coating.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"57 1","pages":"730 - 739"},"PeriodicalIF":1.8,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43251295","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}

Electrochemical results demonstrate that the inhibition increases with a high concentration of imidazole derivatives; the inhibitory efficiency reaches a maximum of 94% at 10–2 mol L−1 for BIM. SEM morphology and EDS analysis show that these derivatives are adsorbed onto the brass interface, the brass sample is effectively protected and the surface becomes relatively flat, which is more significant in the presence of 1H-benzimidazole. FTIR results confirm the retention of BIM on the interface of Cu-Zn alloys. In addition, quantum chemistry calculation manifests that the three derivatives can reveal high anticorrosion properties. Molecular dynamics simulation data manifest that the three imidazole derivatives can be adsorbed at the brass surface in a paralleled way, and have large binding energy. Highlights A new action of imidazole derivatives to mitigate brass corrosion was explored in HNO3. BIM showed inhibitory efficiency more than 94% in HNO3 solution. The inhibition mechanism is studied using SEM/EDS surface analysis and FTIR analysis. The calculated adsorption energies are ranked in the following order: BIM > MIM > IM. Theoretical and experimental results lead to used imidazole derivatives as potential corrosion inhibition for brass in solution.

Potentiodynamic polarisation (PD), electrochemical impedance spectroscopy (EIS) and electrochemical noise measurement (EN) were employed to investigate their corrosion behaviour in 3.5% NaCl solution. The results show that with bipolar pulse mode for PEO process, the growth rate of PEO coating on magnesium alloy first decreased and some micropores were present inside the PEO coating. With the increasing oxidation time, the PEO coating became much homogeneous and the porosity of the coating decreased largely, and the corrosion resistance of PEO coating was enhanced. The use of the bipolar pulse mode is beneficial to the improvement of the compactness and corrision performance of magnesium alloy with PEO treatment for the higher voltage stage and longer oxidation time.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"57 1","pages":"654 - 672"},"PeriodicalIF":1.8,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47177384","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}

In the present study, a Si-modified ferritic martensitic steel was exposed to oxygen-saturated LBE at 500°C at various times and the interface between the internal oxidation zone and matrix was investigated. Microstructural characterisation reveals that grain boundaries and martensitic lath boundaries provide a fast pathway for oxygen diffusion, resulting in the high amount of oxidation products, as well as cracks. The internal stress caused by the formation of oxidation products along grain boundary results in the proliferation of dislocations, which subsequently play as the new diffusion channel for oxygen. The chemical analysis demonstrates that Si preferably concentrates along the dislocations in a form of Si-rich oxide, suggesting the oxidation of Si is prior to the Cr-rich oxide.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"57 1","pages":"648 - 653"},"PeriodicalIF":1.8,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48681522","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}
