Schematic diagram illustrating the addition of metal ions to the surface coating of titanium and its alloys using micro-arc oxidation technology. (A) Micro-arc oxidation process: electrolytic tanks are placed in the electrolyte containing metal ions, and a titanium sheet or titanium alloy is connected to the anode. By adjusting the voltage, current, and time parameters, a stable coating of metal ions can be prepared on the surface of the titanium sheet or titanium alloy. (B) Top view of the surface of titanium alloy without micro-arc oxidation treatment. (C) Top view of the surface of titanium alloy prepared by micro-arc oxidation treatment with a metal ion coating.
