The corrosion features of micro-arc oxidation coatings (MAO coatings) precipitated on 6061-Al alloy at a current density of 1.61 amp/ cm2 were examined in this work. To assess the resistance of corrosion of MAO coatings, simple immersion, and potentiodynamic polarization experiments were performed in 3.5 % NaCl. Long-term immersion testing of coated samples (up to 100 hours) revealed no weight change as compared to uncoated alloy. When associated with the bared alloy, the curves of anodic polarization for MAO-coated specimens showed a much reduced current of corrosion and greater positive potential of corrosion.
