Protective oxide coatings on Mg-Mn-Ce, Mg-Zn-Zr, Mg-Al-Zn-Mn, Mg-Zn-Zr-Y, and Mg-Zr-Nd magnesium-based alloys

Protective coatings are formed on different magnesium-based alloys (Mg-Mn-Ce, Mg-Zn-Zr, Mg-Al-Zn-Mn, Mg-Zn-Zr-Y, and Mg-Zr-Nd) by plasma electrolytic oxidation. Electrochemical and mechanical properties of the coatings are studied, as well as their chemical and phase compositions and structures. Analysis of the data obtained revealed the reasons for the differences in the corrosion and mechanical characteristics between plasma electrolytic layers formed on different magnesium alloys used in aviation and space engineering.
