Summary: Localized plastic deformation has been found to make nuclear reactor components more susceptible to stress corrosion cracking (SCC). By analyzing the surface reactivity and corrosion behavior of deformed stainless steel specimens, research has shown that regions with higher dislocation concentrations exhibit increased reactivity due to a reduction in corrosion activation energy. The combination of surface reactivity and strain distributions suggests that SCC cracking is likely to occur in areas with localized strain where micro-galvanic corrosion is favored.

Summary: Al2O3 ceramic coatings prepared via micro-arc oxidation on AlSi10Mg selective laser-melted components showed that energy density and (NaPO3)(6) content have significant effects on the microstructure and corrosion properties of the coatings. Changes in coating composition, surface roughness, and corrosion resistance were observed with the increase in energy density and (NaPO3)(6) content.

Summary: The influence of sodium fluoride (NaF) concentration in silicate basic electrolyte on the corrosion resistance and biodegradability of micro-arc oxidation (MAO) coatings on Mg2Zn-Mn (ZM21) alloys was investigated. The results showed that increasing NaF concentration to 1.0 g/L resulted in a thicker and more hydrophilic MAO coating. Adding 1.0 g/L NaF enhanced corrosion resistance and adhesion, while excessive NaF concentration (> 1.0 g/L) reduced breakdown voltage and degraded coating quality. The MAO samples demonstrated reduced weight loss rate and pH value after immersion, indicating certain biological safety; and cytotoxicity and cell adhesion tests confirmed their biocompatibility.

Summary: In this study, Mg-2Zn-Mn alloy was surface modified using micro-arc oxidation (MAO) technique. The influence of potassium fluotitanate (K2TiF6) concentration in silicate basic electrolyte on the corrosion resistance and degradation of MAO coatings was investigated. It was found that TiF62- has a thickening effect on the coatings, and adding 0.25 and 0.50 g/L K2TiF6 results in better corrosion resistance. TiF62- concentration also affects the coating quality through the generation of F-. Anatase TiO2 formed by ionization of TiF62- plays a role in sealing the micro-pores of the MAO coating. The surface-modified Mg alloy exhibits improved hydrophilicity, reduced weight loss rate and pH value after immersion, and improved biocompatibility.

Summary: The material of the EIS-based sensor was optimized in this study to monitor the in-situ electrolyte layer thickness (hs) under marine atmosphere. It was found that using easy-corrosion materials could introduce high-frequency dispersion in EIS curves and cause unpredictable changes in electrolyte conductivity, leading to inaccurate measurement of hs. However, a Ni sensor with a thin and corrosion-resistant oxide film could eliminate these distractions and achieve accurate hs response in dynamic environments. Finally, methods for optimizing EIS-based sensor were summarized, providing a new approach for hs monitoring.

Summary: This study extensively investigated the passive film formation mechanisms on Ti-xNb alloys using electrochemical techniques such as EIS and MS measurements, as well as XPS and TEM analysis. It was found that Ti40Nb had lower corrosion resistance due to a thinner passive film compared to commercial pure Ti and Ti12Nb. The passive film formed on Ti12Nb and Ti40Nb alloys under steady-state conditions consisted of amorphous phases of TiO, Ti2O3, TiO2, Nb2O5, and crystalline phases of TiO2 (anatase) and Nb2O5.

Summary: 2,3-pyrazine dicarboxylic acid (PDA), when mixed with potassium iodide (KI), shows promising efficiency as a corrosion inhibitor for Cu-Ni alloys in 2% HCl. An optimum PDA concentration of 1500 ppm provides protection against corrosion, with an average impact of 39% on 90Cu-10Ni and 55% on 70Cu-30Ni. The addition of 5 mM KI significantly enhances the efficiency of PDA, reaching 73% (90Cu-10Ni)/92% (70Cu-30Ni) at room temperature.

Summary: In this study, a passive sealant (PSG) was prepared using the sol-gel method to seal and repair the passive film of Fe-based amorphous coating. The results showed that PSG penetrated the coating with a depth of over 180 μm, increasing the density of the coating. The decrease in donor density and the increase in passive film thickness indicated a slower diffusion rate of point defects. Additionally, the concentrations of Fe2O3 and Cr2O3 increased as the immersion time extended, showing the improved passive ability of the coating.

Summary: The long-term corrosion resistance of conventional micro-arc oxidation (MAO) coatings on magnesium alloy is limited by the inherent micro-scale pores. Zeolitic imidazolate framework-8 (ZIF-8) and zinc gluconate (ZnG) loaded ZIF-8 (ZnG@ZIF-8) were synthesized and incorporated into the MAO coating to enhance the corrosion resistance. The (ZIF-8 + ZnG@ZIF-8)/MAO composite coating showed significant improvement in corrosion protection compared to the blank MAO coating.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
