Summary: Magnesium alloys have excellent mechanical and physical properties, but their poor corrosion resistance hampers their application in aqueous and atmospheric environments. To address this issue, a new sol-gel coating using polydopamine was developed, which significantly improved the corrosion protection performance of magnesium alloy AZ31. This coating demonstrated enhanced durability and provided long-term corrosion protection for over 20 days in an aqueous NaCl solution, compared to unmodified coatings that failed after only 3 days of immersion.

Summary: This study investigates the effect of pH on the structure and corrosion protection properties of sol-gel coatings, with a special focus on a broad pH range (pH = 1-10) during the sol synthesis process. Measurements of sol viscosity, molecular weight, particle size, and structural analysis of the sol-gel coatings reveal the highest condensation degree in samples with pH = 4. Electrochemical, localized electrochemical techniques, and morphology characterization demonstrate that the coatings with pH = 4 exhibit the best corrosion resistance. The results indicate that a high condensation degree leads to a compact and stable three-dimensional sol-gel network with a high crosslinking density and less silanol content, providing highly effective corrosion protection.

Summary: In this work, post-treatment sol-gel methods using acidic and alkaline TEOS solutions were applied to refine the porous network of ZrO2 coating and improve corrosion resistance. The alkaline TEOS solution resulted in the formation of a dense SiO2 interlayer and narrowed pores in the coating, providing the best barrier performance. On the other hand, the acidic TEOS solution mainly formed thin SiO2 layers on the ZrO2 coating surface, leading to poor barrier performance due to electrostatic repulsion forces.

Summary: Autonomous healing coatings based on hybrid organic-inorganic sol-gel coatings impregnated with chrome-free corrosion inhibitors such as Zr4+ and various rare-earth elements were investigated. The effects of direct addition of corrosion inhibitors and halloysite nanoclay encapsulated corrosion inhibitors on coating performance and self-healing action were evaluated. The study showed that coatings derived from the direct addition of Zr4+ and Ce3+ exhibited excellent performance, while all Z/RE-H coatings had a higher current density of 10(-6) A/cm(2) compared to other rare-earth elements and nanoclay encapsulated coatings.

Summary: In this study, a Si/Zr based sol-gel coating was deposited on 316L stainless steel plates with different surface states produced by passivation or electropolishing. The coating thickness and topography were affected by the initial surface state of the substrate, but did not significantly alter the tribocorrosion response of the SG systems. Both systems showed an increase in current during sliding contact cycles, indicating corrosion activity.

Summary: Due to the porous nature of the coatings produced through the plasma electrolytic oxidation (PEO) process, sol-gel coatings have been widely studied as a post-treatment to enhance the protective characteristics. This study investigated the sealing ability and corrosion resistance properties of four types of PEO/sol-gel coating systems on AA2024 alloy using different sol-gel precursors. The performances of the coatings were evaluated through electrochemical impedance spectroscopy (EIS) and Scanning Vibrating Electrode Technique (SVET) analysis. The results showed that the sealing ability and corrosion resistance of the duplex PEO/sol-gel coating were greatly influenced by the sol-gel precursors and their network properties.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
