Summary: This study aimed to achieve and improve the dual self-healing and corrosion resistance properties of Micro-arc oxidation (MAO) coatings. By incorporating ternary Mg-Al-La layered double hydroxides (LDHs) and graphene oxide (GO) into the coating, a hybrid coating with excellent anticorrosion ability and self-healing properties was formed. The coating exhibited strong barrier properties from GO and LDHs and was able to self-heal when exposed to corrosion ions, making it an effective corrosion protection material.

Summary: In this research, high-performance ZnAl-layered double hydroxides (ZnAl-LDHs) with different Zn2+ concentrations were prepared on the surface of an anodized 1060 aluminum alloy. The influence of Zn2+ concentration on corrosion resistance and tribological behavior was explored. The results showed that with the increase in Zn2+ concentration, the thickness and bonding strength of the coatings increased, while the hardness decreased. The ZnAl-LDHs/AAO composite coating with a Zn2+ concentration of 0.3 mol/L exhibited the best anti-corrosion ability and excellent friction-reduction and anti-wear properties.

Summary: The MgAl Layered double hydroxides (LDHs)/graphene oxide (GO) composite film was synthesized in situ on the micro-arc oxidation (MAO) film of AZ31 magnesium alloy using hydrothermal chemical conversion method. The growth behavior and corrosion properties of the composite film were investigated. The results showed that the composition and morphology of the composite film changed gradually with the extended hydrothermal treatment time, utilizing the self-dissolved cation in the MAO film as the LDHs source. The MAO/LG-12 h coating exhibited higher corrosion resistance (1.28 x 10-9 A/cm2) compared to the MAO coating (8.49 x 10-6 A/cm2), thanks to the synergistic effect of GO and LDHs.

Summary: Zinc-aluminum layered double hydroxides (Zn-Al LDHs) coatings were prepared on the surface of micro-arc oxidized ZK60 magnesium alloy. The coating characteristics were analyzed by scanning electron microscopy, X-ray diffraction, electrochemical impedance spectroscopy, laser scanning confocal microscopy, and Fourier-transform infrared spectroscopy. Ion exchange experiments showed that methionine and cysteine were successfully inserted into the interlayer structure of LDHs. The LDHs-Met and LDHs-Cys coatings exhibited improved porosity, surface roughness, hydrophilicity, and corrosion resistance compared to MAO and MAO/LDHs coatings. The amino acids in LDHs played a significant corrosion inhibition role, effectively enhancing the corrosion resistance of MAO.

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: Mg-Cu alloys show promise as antibacterial implant materials, but their clinical applications are hindered by their high initial biodegradation rate. This study addresses this challenge by using nanotechnology to obtain a gradient nanostructured surface layer, resulting in a significantly lower initial biodegradation rate. The surface nanocrystallization and the fragmentation and re-dissolution of Mg2Cu particles contribute to the reduced degradation rate. Additionally, the nanomodified Mg-0.2 Cu alloy exhibits good antibacterial efficacy. Overall, this study creatively applies surface mechanical grinding treatment (SMGT) to produce a high-performance Mg alloy implant material.

Summary: This review paper introduces a research project that aims to quantify the inhibition of gaseous hydrogen embrittlement by oxygen, with potential application in gas transmission pipelines. It summarizes compelling laboratory evidence that oxygen may inhibit gaseous hydrogen embrittlement. Quantification of the oxygen inhibition of gaseous hydrogen embrittlement is necessary in order to evaluate the effectiveness of this approach in inhibiting hydrogen embrittlement in gas transmission pipelines. The experimental approach involves quantifying the amount of hydrogen entering the steel from hydrogen-containing gas mixtures using a purpose-built gas phase permeation cell.

Summary: This study investigated the effects of annealing heat treatments on the microstructure, corrosion, and mechanical behavior of wires made from Mg alloy WE43 and Zn alloy Zn7Ag. The strain rate had minimal influence on the mechanical properties of WE43, while decreasing strain rate decreased the strength and increased the ductility of Zn7Ag due to creep. Annealing heat treatments had little effect on the corrosion rate of both alloys, and had minimal impact on the mechanical properties of WE43, but tended to decrease ductility and eliminate strain softening in Zn7Ag.

Summary: The effect of Cu alloying on hydrogen embrittlement (HE) in TWIP steel was investigated. Cu alloying influenced HE resistance through several mechanisms including the increase in stacking fault energy, refinement of austenite grains, reduction of diffusible hydrogen content, and dispersion of mechanical twins by Cu precipitate/Cu-rich clusters. Among these mechanisms, (iv) exhibited the greatest improvement in HE resistance in the 700°C annealed Cu-alloyed TWIP steel.

Summary: A novel coating on the Mg1Mn alloy was produced by anodic polarization combined with hydrothermal treatment (AP + H) in 0.1 M Na2CO3 solution. The coating consisting of MgCO3, Mg(OH)(2), and MgO provided satisfactory protection in 3.5 wt% NaCl, but showed increased corrosion rate after 72 hours. The failure of the coating was attributed to second phase particles or impurities in the matrix. The AP + H coating is considered suitable as a primer coating for Mg applications in kitchen ware, biomedical areas, or industry.

Summary: The present study compares the grain-refining efficiencies of Ti nanoparticles and LaB6 nanoparticles as inoculators in a 2024 Al alloy during additive manufacturing (AM). The experimental results reveal that Ti nanoparticles have a more pronounced refinement effect and lead to a fine, fully equiaxed microstructure, while LaB6 nanoparticles have almost no refining effect on the alloy. Further analysis suggests that the higher refining efficiency of Ti inoculation is attributed to the incorporation of Ti solute and the in situ-formed L1(2)-Al3Ti nucleation particles. This work highlights the importance of incorporating appropriate solutes to generate sufficient undercooling for the activation of heterogenous nucleation in AM.

Summary: The corrosion behavior of Nd alloyed magnesium alloy AZ80 in three simulated concrete pore solutions (SCPs) was investigated. The composition and pH value of the SCPs were found to have an effect on the corrosion properties of AZ80 and AZ80-1.0Nd. Corrosion mainly occurred in the form of localized corrosion along the transverse direction in the SCP solutions. AZ80 and AZ80-1.0Nd showed the best corrosion resistance in the SCP2 solution due to the formation of a dense protective film. AA6061 corroded severely in the SCP1 solution and suffered less corrosion in the SCP2 and SCP3 solutions.
