Formation characterization of hydroxyapatite on titanium by microarc oxidation and hydrothermal treatment

Journal of Bioscience and Bioengineering, 2005
Microarc oxidation (MAO) was performed on titanium in an electrolyte containing calcium glycerphosphate (Ca-GP) and calcium acetate (CA) using a direct current power supply. It was found that the MAO method is suitable forming a ceramic coating containing Ca and P using titanium, and that films display a porous and rough structure on their surface ...

Bioactivity Study of the Titanium Plates Treated with Microarc Oxidation and Alkali

Journal of Nanoscience and Nanotechnology, 2011
Microarc oxidation (MAO) and alkali treatment was used to modify the surface of titanium, which prepared different microstructure and nanostructure TiO2-based coating on titanium. The samples were analyzed by scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and contact angle measuring instrument.

EFFECT OF EXCESS NEGATIVE IONS ON ANODIC OXIDATION IN MICROARC OXIDATION OF TITANIUM

Modern Physics Letters B, 2009
The effects of the electrical bias conditions on oxide film during titanium MAO (microarc oxidation) were investigated. Since DC voltage showed very low stabilized currents but produced oxide films with poor quality, the magnitude of applied voltages, duty cycles, and frequencies were modulated to control the quality of the oxide film.
