The weakness of wear resistance and corrosion resistance of titanium alloy has become a bottleneck restricting the use of titanium alloy. In this work, the micro-arc oxidation coating is performed on TC11 sample in electrolyte prepared by sodium silicate (Na₂SiO₃) and sodium tungstate (Na₂WO₄). Scanning electron microscopy (SEM), X-ray diffraction (XRD), micro-hardness tester are used to observe the coating surface and cross-sectional morphology, micro-hardness of the inner and outer ceramic coating. The coating is mainly composed of TiO₂, γ-Al₂O₃, and Al₂TiO₅. TiO₂ consists of anatase-TiO₂ and a small amount of rutile-TiO₂. The outer coating contains a large amount of amorphous SiO₂. The electrochemical corrosion and general corrosion of the coating are comparatively analyzed in 3.5% NaCl and 30% H₂SO₄ solution, and the coating obtained in the 30% H₂SO₄ solution has a lower self-corrosion current density. Finally, the wear mechanism of the coating is studied by the anti-wear experiment with SiC.
