The calculation accuracy of the theoretical model of corrosion amount was verified by measuring the corrosion amount of steel bars under different magnetic field strengths through the accelerated corrosion test of steel bars. The electrochemical parameters of polarization curve in the process of steel bar corrosion was measured by electrochemical test, and the influence of magnetic field on corrosion potential of steel bar was discussed. The results show that: 1) With the increase of magnetic induction intensity, the degree of steel corrosion increased, and the influence of vertical magnetic field on steel corrosion was greater than that of parallel magnetic field. 2) With the increase of magnetic induction intensity, the corrosion potential gradually shifts negatively, and the resistance of oxidation products on the surface of steel bar gradually decreases. 3) The theoretical corrosion amount based on MHD was closer to the measured corrosion amount than the theoretical corrosion amount based on Faraday.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"255 ","pages":"Article 113082"},"PeriodicalIF":7.4,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144239510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparing the SiC-Si,B and SiC-Si model composites clearly demonstrates the boron's protective effect. Yet, the SiC-Si,B sample shows a macroscopic reactivity gradient related to the progression of the Si,B alloy through the porous SiC network. Electron energy loss spectroscopy (EELS) and atom probe tomography (APT) were used to assess elemental composition at the quasi-atomic and trace scales, in the different phases and at SiC/Si,B interfaces. Boron diffuses into bulk SiC, in agreement with thermodynamic calculations, but also concentrates at structural defects in polycrystalline CVD SiC. EELS and APT both revealed a high boron overconcentration over a few nanometers at SiC/Si,B interfaces, without intermediate layer visible by TEM. Raman spectroscopy also evidenced a microscale gradient of substituted boron in the Si,B alloy, near SiC/Si,B interfaces, which was related to a high carbon concentration and an unexpected carbon environment. These results led to conclude that the addition of boron cumulates three beneficial effects limiting SiC reactivity: (1) a volume effect in SiC, stabilizing and accommodating structural defects (2) an interfacial effect, with B atoms concentrating and stabilizing SiC/Si,B interfaces, and (3) a volume effect in the Si,B alloy, forming B-C clusters inhibiting carbon diffusion.

Effect of Sn modification on the corrosion resistance and electrical conductivity of coatings was particularly focused on under simulated PEMFCs conditions. The results indicated that the Ti₂(Al, Sn)C coating significantly improved electrical conductivity and corrosion resistance compared to the pristine Ti₂AlC coating. The observed phenomena in Ti₂(Al, Sn)C coating could be attributed to the unique appearance of passivation layer, where three layers—TiO₂, Al₂O₃ and SnO₂— were identified distinctly. One benefit was that the outermost SnO₂, resulting from the oxidation of Sn, partially inhibited the penetration of corrosive media. This enhancement improved the protective efficiency of the subsequent Al₂O₃ layer, which has a higher density than that of TiO₂ layer. On the other hand, the microstructure evolution of the passivation film was also well consistent with the capability of atomic diffusion, as indicated by the atomic vacancy formation energy and the migration energy by density functional theory simulation.

The incorporation of 0.3 g/L ST effectively stabilized the colloidal state of Ti₃C₂T_<em>x</em> nanosheets, ensuring their uniform dispersion within the urushiol matrix.

However, the protective mechanisms remain unclear. This study investigated the role of different <em>A</em>₆<em>B</em>₂O₁₇ oxide scales formed on five multicomponent carbide ceramics (Zr_0.75Nb_0.25C, Zr_0.75Ta_0.25C, Hf_0.75Nb_0.25C, Hf_0.75Ta_0.25C, and Zr_0.375Hf_0.375Nb_0.125Ta_0.125C) during oxyacetylene ablation.

The protective performance of these oxides depends on the <em>A</em>/<em>B</em> elements.

Notably, the (Zr, Hf)₆(Nb, Ta)₂O₁₇ scale formed on Zr_0.375Hf_0.375Nb_0.125Ta_0.125C shows exceptional ablation resistance and achieves the thinnest thickness.
