A kind of environmentally friendly anodizing route for magnesium alloys, based on a new kind of organic additive (AA) contained traditional alkaline borate solution and 50 Hz civil ac current, has been studied. It is found that the formation of the anodic films is always coupled with the additive depended sparking and oxygen evolution, and the optimized ivory-white smooth anodic film possesses high corrosion resistance and excellent binding strength to AZ31 substrate. Meanwhile, The results also show that the structure, the corrosion resistance and the morphology of the anodic films are mainly dependent on the anodizing voltage, time and additives.

- Anodizing of magnesium alloy AZ31 in alkaline solutions with silicate under continuous sparking (2008, background): “Recently, many researches focused on the selection of electrolyte, such as alkaline solution with additives just as phosphate, silicate, borate, and organic substances [7–10].”
- Study of the structure and corrosion behavior of PEO coatings on AM50 magnesium alloy by electrochemical impedance spectroscopy (2008, methodology): “Comparing the EIS data of PEO coatings obtained using phosphate solution and reported in the literature for AZ91 and AZ31 alloys [3,4,15,16] with that of AM50 alloy, it can be said that the present coatings exhibit reasonable Rf2 values and hence these coatings show appropriate corrosion resistance.”
