The aim of this work is to study how applied voltage in stages incorporates into the prepared micro arc oxidation (MAO) coatings on titanium and control the characteristics and resistances. The microstructure of MAO coatings were characterized by scanning electron microscope (SEM) and laser scanning confocal microscopy, and the coating composition were analyzed by energy dispersive spectrometer (EDS) and X-Ray diffraction (XRD). Thickness, roughness and corrosion resistance of coatings were evaluated. Compared with the coating obtained in different applied voltage stages, the coating formed on substrate alloy with first applied voltage is 320V for 180s and second applied stage is 420V for 720s showed a minimal roughness. The coating with first applied voltage is 320V for 120s and second applied stage is 420V for 780s exhibits a dense micro structure and the best corrosion resistance. The XRD result shows that the MAO coating is composed with TiO2 and Ti2O3 in metastable state.
