A one-step in-situ hydrothermal treatment is carried out on pure Mg to prepare magnesium hydroxide coating with enhanced corrosion resistance. A uniform and compact coating with about 17 μm in thickness was formed on pure Mg substrate by hydrothermal treatment at 150 ℃ for 5 h with pH value equaling to 10. The coating displayed a dense self-assembled cage-like braiding structure and well bonded with the substrate. The sample with this coating exhibited the most positive corrosion potential and the lowest corrosion current density during electrochemical test in simulated body fluid (SBF). The relationship between the morphology, packing models and size of particles with different preparation conditions was discussed.

对纯Mg进行一步式原位水热处理，以制备具有增强的耐腐蚀性的氢氧化镁涂层。通过在150℃下进行5h的pH等于10的水热处理在纯Mg衬底上形成厚度为17μm的均匀致密的涂层。该涂层表现出致密的自组装笼状编织结构，并牢固地结合在一起。基板。在模拟体液（SBF）中进行电化学测试期间，具有这种涂层的样品表现出最大的正腐蚀电位和最低的腐蚀电流密度。讨论了不同制备条件下颗粒的形貌，堆积模型与粒径的关系。
