摘　　要：采用正交试验,开发出一种新型环保镁合金阳极氧化的电解液配方,研究在此工艺下形成的阳极氧化膜的耐蚀性。采用EDAX、XRD、SEM对阳极氧化膜的成分、结构和形貌进行研究。结果表明,获得的陶瓷层分布均匀,表面光滑致密,耐蚀性显著加强。Through orthogonal test, a new environment--friendly electrolyte for anodizing of magnesium alloys were developed, and study of corrosion resistance in the formation of anodized film. The component, structure and surface micrograph of the film were studied by EDAX, XRD and SEM.The results show that the ceramic coating evenly distributed and surface more compact, corrosion resistance significantly strengthened.
