In this work; a plasma electrolytic oxidation process was applied to AZ91 and AM50 magnesium alloys and commercially pure magnesium to produce a protective surface layer. The plasma electrolytic oxidation process was carried out in an alkaline phosphate solution with a DC power supply; using relatively high current densities and short treatment times. The influence of some important process parameters such as current density; treatment time and voltage was studied. The layers were characterised by scansion electron microscopy; X-ray diffraction and X-ray photoelectron spectrometry; in order to investigate the effect of the process parameters on the microstructure and chemical composition. The corrosion resistance properties of the obtained layers were investigated by potentiodynamic anodic polarization and electrochemical impedance spectroscopy tests. The current density; applied during the treatment; influenced the morphology and the thickness of the coatings; and; consequently; the corrosion resistance. The corrosion tests evidenced that the layers obtained with plasma electrolytic process provided a good corrosion protection to the magnesium and magnesium alloys. © 2014 Springer Science+Business Media Dordrecht;
