摘　　要：以纳米碳化钛(TiC)为添加剂,研究其对镁合金阳极氧化过程的作用机制,通过扫描电子显微镜、X射线衍射试验、塔菲尔腐蚀试验等表征氧化膜的形貌结构与性能。结果表明:添加纳米碳化钛能有效改善镁合金的阳极氧化过程,提升镁合金氧化膜的耐腐蚀性能;当添加3~4 g·L^(-1)纳米碳化钛时,获得的氧化膜性能最佳。Nano-titanium carbide(TiC)was used as additive to study the mechanism of its action on the anodic oxidation process of magnesium alloy.The morphology,structure and properties of the oxide film were characterized by scanning electron microscopy,X-ray diffraction test and Tafel corrosion test.The results show that the addition of nano-titanium carbide can effectively improve the anodic oxidation process of magnesium alloy and enhance the corrosion resistance of magnesium alloy oxide film.When 3~4 g·L^(-1)nano titanium carbide is added,the performance of the oxide film is the best.
