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: The corrosion behavior and corrosion rate of friction stir welded AZ31B magnesium alloy and 6N01 aluminum alloy dissimilar joints were studied using real-time imaging, potentiodynamic polarization, EIS, and hydrogen evolution tests. The corrosion rate was found to increase in the order of Al base metal < Mg base metal < stirred zone. The galvanic coupling of the Mg phase to other phases enhanced the corrosion of both base metals, and intense corrosion at BM-AZ31B elevated the interfacial pH due to water reduction on the cathodic particles of BM-6N01.

Summary: A V/Ce conversion coating was deposited on the surface of AZ31B magnesium alloy using a solution containing vanadate and cerium nitrate. The composition and morphology of the coating were examined, revealing a thin and cracked coating with scattered spherical particles. The corrosion behavior of the substrate and conversion coating was studied through potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Compared to the bare AZ31B, the corrosion current density of the conversion coating decreased significantly, and the total impedance of the coating increased. The conductivity of the coating was found to be dependent on the semiconductor properties of the phase compositions.

Summary: In this study, an anodized coating was prepared at low voltage on AZ31B Mg alloy, followed by one-step hydrothermal treatment to produce stearic acid modified CeO2 coating with superhydrophobicity. The anodized coating combined well with the substrate, and the outer stearic acid modified CeO2 coating covered the inner anodized coating compactly. The composite coating showed excellent superhydrophobicity and self-cleaning performance, while greatly improving the corrosion resistance of the substrate. The Ce ions released from the coating upon scratching might prevent further corrosion, exhibiting self-healing behavior.

Summary: A novel method of ultrafast femtosecond laser surface processing combined with post thermal oxidation treatment was employed to improve the corrosion resistance of AZ31B magnesium alloys. The laser processing created nanostructures and hierarchical micro/nanostructures on the alloy surfaces, which weakened the corrosion resistance in chloride solutions. However, after the post thermal oxidation treatment, an enhancement in corrosion resistance was observed due to the formation of a dense film that improved the protective ability of the alloys and inhibited uniform corrosion.

Summary: This study investigated the influence of fluoride ions on the growth of PEO/Ni-P composite coating on magnesium alloy AZ31B. It was found that fluoride ions can increase the thickness and compactness of the PEO coating but hinder direct EN plating, with Ni-P nodules selectively nucleating in the micro-pores of the PEO layer. The PEO/Ni-P composite coating provides superior corrosion protection to the magnesium substrate.

Summary: Micro-arc oxidation (MAO) is an effective and environmentally friendly method for generating dense and homogeneous coatings with high corrosion resistance on magnesium alloys. However, the porous structure of MAO coatings can lead to reduced corrosion resistance due to the invasion of corrosive media. In this study, a novel one-step in situ growth of a pore-sealing coating on MAO-coated AZ31B alloy was achieved by hydrothermal treatment. The resulting coating effectively seals the micro-pores and micro-cracks of the MAO coating and exhibits improved corrosion resistance.

Summary: The outdoor corrosion behavior of AZ31B magnesium alloy in the Antarctic atmospheric environment was investigated in this study. The surface corrosion state of the specimens exposed for 1 month and 24 months differed significantly. The corrosion rate decreased from 19.82 g/m(2)·year after 1 month to 13.87 g/m(2)·year after two years' exposure. Corrosion initiates with pitting corrosion and evolves to uniform corrosion with prolonged exposure time. The skyward surface exhibits more severe corrosion than the groundward surface, attributed to the long-term existence of the adsorbed electrolyte layer. The dominant phases of the corrosion products formed on the alloy exposed in the Antarctica environment are MgCO3·3H(2)O initially and Mg2CO3(OH)2·0.5H(2)O after long-term exposure.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.
