With the aim of improving the corrosion and wear resistance of pure magnesium, La₂O₃ nano-particles are added into the PEO electrolyte. The influence of the particles on coating formation, morphology and performance is investigated. Results indicate that the porosity and thickness decrease remarkably after the particle incorporation which influences the corrosion and wear resistance in return. The coating with 1 g particle addition shows lowest porosity and highest hardness value, resulting in superior corrosion and wear performance, which implies the feasibility of the proposed strategy in fabricating functionalized PEO coatings on Mg-based materials.

纯镁表面掺杂La2O3等离子电解氧化涂层的腐蚀和磨损性能

为了提高纯镁的耐腐蚀性和耐磨性，在PEO电解液中加入了La ₂ O _{3纳米粒子。}研究了颗粒对涂层形成、形态和性能的影响。结果表明，颗粒掺入后孔隙率和厚度显着降低，反过来影响了耐腐蚀性和耐磨性。添加 1 g 颗粒的涂层显示出最低的孔隙率和最高的硬度值，从而具有优异的腐蚀和磨损性能，这意味着所提出的策略在镁基材料上制备功能化 PEO 涂层的可行性。
