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: In this study, a micro-arc oxidation (MAO) process with calcium was introduced to improve the interfacial strength of Titanium with a bioceramic hydroxyapatite (HA) coating. The MAO coating comprised porous TiO2 with Ca or CaTiO3, and the HA coating on the MAO coating was confirmed to be plate-like Ca-deficient HA. The MAO coating containing Ca as a connecting interlayer showed promising results in improving the HA adhesion strength with an adhesive strength of 2.326 MPa.

Summary: In this study, Al2O3-ZrO2 ceramic coatings were prepared on 6061 Al alloy using MAO and SLM methods. The MAO coatings exhibited a porous structure and progressive oxidation of the substrate, while the SLM coatings were denser with cracks observed on the surface. XRD analysis revealed that the ceramic coating in the MAO process consisted of m-ZrO2, t-ZrO2, and gamma-Al2O3 phases, while a Zr3O phase was also present in SLM. The MAO Al2O3-ZrO2 coating exhibited higher hardness compared to the SLM coating, and the Young's modulus of the MAO coating was lower due to higher porosity. The in-situ oxidation, heating, and solidification processes and transformation mechanisms were discussed and compared for MAO and SLM.

Summary: This study introduced copper into the MAO coating on TC4 alloy to enhance its wear performance and antibacterial properties. The addition of copper created a porous structure with Cu mainly concentrated around micropores, forming CuO and Cu2O in the coating. Despite a reduction in hardness, the presence of Cu helped reduce friction and improve wear resistance in simulated seawater. Additionally, the antibacterial effects of Cu were evident in the 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.
