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: A density functional theory (DFT) study was conducted to investigate various properties of (Gd1-xSmx)2Zr2O7, including mechanical stability, thermal conductivity, Debye temperature, electronic structure, and defect chemistry. The compounds exhibited excellent structural and mechanical stability, with (Gd0.25Sm0.75)2Zr2O7 showing the lowest Young's modulus, highest Possion's ratio, lowest Debye temperature, and lowest thermal conductivity. The study also examined the formation energies of various defects and observed that Sm-doped Gd2Zr2O7, especially GdSmZr2O7, exhibited improved irradiation tolerance. Furthermore, after ion irradiation, the crystal structure of GdSmZr2O7 transformed from pyrochlore to a defect fluorite without amorphous phase.

Summary: In situ sintering experiments performed in a transmission electron microscope show that the densification rate can follow interface nucleation rate limited kinetics. This study conducts in situ sintering experiments on immiscible Al2O3-GdAlO3 interfaces, allowing for statistical analysis of sintering at a single interface type as a function of time and temperature. The data provide a measure of the activation energy for the nucleation process, which is asymptotic to 4.8 eV. The development of a new sintering model based on interface nucleation rate limited kinetics demonstrates its effectiveness in predicting various sintering data.

Summary: The motion of grain boundary dislocations is responsible for grain boundary plasticity during processes like creep and stress relaxation. However, creep at low stress levels, known as non-Newtonian grain boundary creep, is not well understood. Previous models for nucleation rate limited creep have not been adequately developed. In this study, a model for nucleation rate limited kinetics is developed and shown to accurately describe existing creep data using realistic materials properties as inputs.

Summary: Preparation of coatings with excellent properties is an effective way to address the poor wear and corrosion resistance of aluminum alloys. Micro-arc oxidation (MAO) coatings exhibit high hardness, good adhesion, and excellent corrosion and wear resistance. However, defects such as micropores, cracks, overgrowth regions, and residual stress in MAO coatings are unavoidable, making it more difficult to control the surface properties associated with corrosion resistance, wear resistance, adhesion, and fatigue performance.

Summary: A NbSi2/SiO2-Nb2O5/HfSi2-HfO2 multilayer ceramic coating with Hf-rich out layers was designed and prepared on a dense NbSi2 surface to enhance oxidation resistance. The coating showed a lower mass gain (40%) compared to the NbSi2 coating after 100 hours at 1200 degrees C. The presence of HfO2 and HfSiO4 phases anchored in the SiO2 scale improved the structural stability of the ceramic phase and blocked oxygen penetration, inhibiting Nb-oxide growth and crack initiation.

Summary: This study investigated the characteristics of PEO processes on SiCp/Al composite in aluminate electrolyte under the influence of negative pulse, aiming to tailor the soft sparking discharge states, thus achieving the compact ceramic coating and providing a deep understanding of the mechanisms involved. The results showed that large negative voltage accelerates the transition from arc sparking discharge to soft sparking discharge, and when the PEO process completely enters the soft spark discharge state, the lowest electron density can also be kept at 1.06 x 10^22 m-3, reaching the local thermodynamic equilibrium condition. Additionally, the introduction of negative voltage effectively reduces the irregular convex structures and the macropores in the coating, due to inhibiting destructive high-intensity spark discharge by the soft sparking discharge.

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.
