Abstract Dense ceramic coatings were fabricated on TA15 by micro-arc oxidation for improving its hardness and corrosion resistance with NaAlO₂, NaF and KOH as electrolyte. Surface morphology, chemical composition and phase composition of coatings were analyzed. Microhardness, surface roughness and corrosion resistance of coatings for different oxidation time were investigated. The results show that tiny honeycomb-like micro-nano pores could be seen on coatings. With the increase of oxidation time, the surface of coatings gradually became smooth. When the time was too long, pits, bulges and other defects were appeared. The surface roughness of the coatings firstly decreased and then increased. The coating was composed of TiO₂, Al₂O₃ and Al₂Ti₃ phases. The surface microhardness of the coating always increased with the increase of oxidation time. The microhardness of the 50 min treated coating was 332.82HV, which increased by 59.2% compared to the matrix. The corrosion potential of the 40 min treated coating was +222.24 mV, which was 530 mV higher than that of the matrix. The corrosion current density of the 40 min treated coating was 1.73×10^-9A/cm², which was reduced to 3% of the matrix. The 40 min treated coating exhibited the best corrosion resistance.
