Preparation and apatite layer formation of plasma electrolytic oxidation film on titanium for biomedical application

Porous and rough titania film containing Ca and P on titanium was prepared by plasma electrolytic oxidation. The film was composed of titania and a little CaTiO3. Apatite layer was formed on the titania film when the film was immersed in the simulated body fluid, indicating the potencial capability for formation of the plasma electrolytic oxidation film on titanium.
