Synthesis of bioactive ceramic on the titanium substrate by micro‐arc oxidation
Journal of Biomedical Materials Research Part A, 2008AbstractBioactive ceramic films on titanium substrate are prepared successfully by micro‐arc oxidation in electrolyte solution containing NaOH only. The coatings are prepared by micro‐arc oxidation at various applied current densities (200–400 mA/cm2) and in NaOH electrolyte with different concentrations. The XRD shows that they are composed of rutile,
