Abstract
A cost-effective film deposition technique called electrostatic spray deposition (ESD) was used to prepare bioactive calcium phosphate thin films. The hydroxyapatite - forming ability of calcium phosphate films after different immersion times has been investigated in Eagle's minimum essential medium solution. The microstructure of the newly-formed layer on the films was established by a combination of X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. The results show that the layers are carbonated hydroxyapatite after immersion for 15 days.
