Summary: Magnesium has good biocompatibility but high corrosion rate. To reduce the corrosion rate, we coated the magnesium alloy with tannic acid (TA) and hyaluronic acid (HYA). The TA-HYA coating effectively reduced the corrosion rate and improved hydrophilic properties. In vitro tests showed that the coating could bind Mg2+ ions and promote new bone growth.

Summary: This study investigated the effect of surface indentation size on the corrosion behaviour of MAO coated AZ80 magnesium alloy. Various techniques, including laser confocal microscope, scanning electron microscope, X-ray diffractometer and electrochemical test, were used to study the corrosion process and damaged coatings. The results showed that the corrosion current density increased when the MAO coating was damaged with a certain impact height. Furthermore, the corrosion mechanism for coatings with different indentation sizes was clarified.

Summary: The rapid degradation of magnesium alloy limits its application as medical implant materials. Therefore, designing a protective coating with low degradation rate and excellent biological activity is crucial. In this study, a PLGA+MAO composite coating was prepared on a magnesium alloy and its degradation behavior and bone tissue growth were investigated. The results showed that the PLGA+MAO coating had better anti-corrosion performance and stimulated new bone growth. However, localized corrosion may still be an issue and needs further investigation for biocompatibility.

Summary: Ceramic coatings were prepared on the surface of R60705 zirconium alloy using the micro-arc oxidation (MAO) technique. The growth behavior of the MAO coatings at different stages was investigated, revealing both inward and outward growth. The composition of the coatings included m-ZrO2, t-ZrO2, and a small amount of SiO2, with Zr, O, and Si as the main elements. The corrosion resistance of the coatings increased initially and then decreased with increasing oxidation time, with the best corrosion resistance observed at 15 min.

Summary: A Zr-containing micro-arc oxidation-polylactic acid (MAO-PLA) composite coating was prepared to enhance the corrosion resistance of magnesium alloy as a medical implant. The study on the microstructure, phase composition, and corrosion resistance of the coating showed that PLA can seal the micropores and cracks on the surface of the MAO coating, resulting in the lowest corrosion rate for the sealed sample. In the immersion corrosion process with simulated body fluid (SBF), calcium and phosphorus deposits form on the surface of the composite coating, with PLA coating playing a vital role in substrate protection. The composite coating can be used for degradable magnesium-based orthopedic implants.

Summary: Micro-arc oxidation (MAO) is a promising method for enhancing the corrosion resistance of magnesium alloys, but the presence of pores and microcracks limits its effectiveness. In this study, layered double hydroxides (LDH) combined with rGO nanosheets were used to seal these defects on MAO coatings, improving their anti-corrosion properties and surface properties. Incorporating rGO led to reduced surface energy and enhanced performance of the coatings.

Summary: This study investigates the addition of fluoride to the electroless nickel-phosphorus plating solution to improve the corrosion resistance of MAO-coated AZ31B magnesium alloy. Fluoride reacts with Ni2+ ions and the MAO coating to form interphases, which enhance bonding and corrosion resistance. The presence of fluoride in the plating solution results in a more corrosion-resistant coating. The composition, structure, and morphology of the coatings are characterized using various analytical techniques, and their corrosion resistance is evaluated using different tests.

Summary: A novel Cu(II)-Chitosan/PVA electrospun coating with different concentrations of Cu(II) was applied to MAO-pre-treated AZ31 magnesium alloy samples to enhance antibacterial activity, cell viability, and corrosion resistance. The coatings exhibited crack-free, unbeaded, and uniform fibrous structures. They showed satisfactory antibacterial activities against both gram-positive and gram-negative bacteria. Higher Cu(II) concentrations resulted in improved antibacterial properties, but also caused significant cytotoxicity.

Summary: Ultrawide-bandgap semiconductor heterojunctions Sc2O3/GaN and theta-Al2O3/GaN were studied using density functional theory (DFT). The dielectric-dependent hybrid (DDH) functional, which accurately describes the dielectric screening in wide-bandgap materials, was used. The calculated band gaps matched with experimental measurements, and both heterojunctions exhibited type-I band alignments with specific valence/conduction band offsets. This study provides a method for predicting band offsets in other wide-bandgap semiconductor heterojunctions.

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.
