Mg alloy is the preferred material for lightweight development of manufacturing industry. However, its application limited due to poor wear resistance and corrosion resistance. In this experiment, Mg–Al layered double hydroxide/steam coating (LDH/SC) composite coatings are prepared on surface LA43M Mg–Li by steam treatment in‐situ hydrothermal method different times (12, 18, 24, 30, 36 h). The morphology structure characterized scanning electron microscopy, energy dispersive spectrometry,...
Abstract A layered double‐hydroxide (Mg–Al LDH) film was grown in situ on an LA103Z magnesium alloy aluminum nitrate solution at 90°C by adjusting the hydrothermal reaction time. The Mg–Al LDH comprised and Mg(OH) 2 , which obtained after treatment for 24 h, thick dense, with a uniform compact sheet growing perpendicular to surface. showed best corrosion resistance, both R p i corr values were two orders of magnitude higher than those substrate. Nevertheless, resistances films 12 30 h poor...
In order to explore the effect of corrosion inhibitor modification on microstructure and resistance MgAl layered double hydroxide (LDH) film LA43M Mg-Li alloy, LDH films were successfully obtained by ion exchange method at different hydrothermal temperatures. Microstructure with anion intercalation characterized SEM, EDS XRD, tested EIS, polarization curve hydrogen evolution experiments. The results showed that modified nanosheets are larger in size, denser slightly thicker than film....
Inhibiting oocyte spontaneous activation (SA) is essential for successful rat cloning by nuclear transfer (NT). This study tested the hypothesis that activities of Na+/Ca2+ exchanger (NCX) would decrease with aging and SA oocytes could be inhibited if intraoocyte Ca2+ rises were prevented activating NCX through increasing Na+ concentrations in culture medium. Elevating levels medium supplementing NaCl oocytes, while maintaining a constant level maturation-promoting factor mitogen-activated...
The heteronuclear metal oxide complexes are of great significance in heterogeneous catalytic oxidation CO. However, previous studies mainly focused on the composition oxide, charge state, support and active oxygen species, with little attention paid to adsorbed CO ligands. Herein, ligand-mediated reactivity niobium–nickel monoxide carbonyl has been successfully identified. NbNiO(CO)n– (n = 5–6) anions determined be O-bridged complexes. In contrast, 7–8) characterized η2-CO2-tagged crucial...
In order to improve the corrosion resistance of magnesium-lithium (Mg-Li) alloy, a micro-arc oxidation (MAO) ceramic layer was first prepared on LA103Z Mg-Li and then MAO coating alloy sealed by layered double hydroxide (LDH) hydrothermal treatment. The obtained samples were subjected immersion test in 3.5% NaCl solution for 8 days. growth characteristics different coatings before studied XRD, SEM EDS. Morphology composition observed after corrosion. Electrochemical composite film performed...
Abstract Magnesia‐alumina layered double hydroxide (Mg‐Al LDH) films grown in situ on LA43M magnesium‐lithium (Mg‐Li) alloy were synthesized utilizing the hydrothermal method. Scanning electron microscopy (SEM), energy‐dispersive spectrometry (EDS), and X‐ray diffraction (XRD) used to characterize surface morphologies, composition, phase of Mg‐Al films. The corrosion resistance was estimated via immersion experiment hydrogen evolution test, tribological properties investigated using wear...
