The barium titanate films have been grown on the surface of the titanium alloy by the micro-arc oxidation.The effect of the electrolyte composition,oxidation time,and micro-arc voltage on the structure and morphology of the films were discussed,and the adhesive strength of the BaTiO3 films was evaluated.The results showed that with increasing the concentration of electrolyte composition and oxidation time the more barium titanate films were formed.The morphology of the BaTiO3 films was influenced by the con...
