Abstract :
Ti-6Al-4V was hydrothermal treated in the solution of sodium dihydrogen phosphate after the process of Micro-arc oxidization (MAO). The phase, composition morphology and biocompatibility of the coatings are characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM) with energy dispersive X-ray spectrometer (EDS). It was found that the adding of sodium dihydrogen phosphate in the hydrothermal solution can help optimal HA growth condition. Inside certain limits, higher concentration of sodium dihydrogen phosphate do not provide a more competitive HA growth condition. The samples treated by such process performance a good bioactivity. Many HA crystals formed after 0.5 day, and HA crystals were formed all through the film after 1 day.
