Investigation on hydroxyapatite coatings formation on titanium surface

Abstract

This study presents an alternative coating method based on biomimetic approach to grow the hydroxyapatite layers on the titanium surface. In order to increase the bioactivity of the titanium surface the anodization and alkali thermal oxidation pre-treatments have been applied. Titanium implants were then coated with a hydroxyapatite layer under biomimetic conditions by using a Simulated Body Fluid (SBF) solution. The apatite deposits were investigated by means of scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR). The obtained results confirmed that the hydroxyapatite coatings on the titanium surface were obtained.
