Protective surface layers with high corrosion resistance (R p = 3.3•105 ohm cm 2 ) and significant microhardness (H = 4.8 GPa), as compared to the substrate material, were obtained on MA8 magnesium alloy by bipolar Plasma Electrolytic Oxidation (PEO) in a silicate-fluoride electrolyte. The phase and
