Hydroxyapatite (HAP, Ca10(PO4)6(OH)2) is a main mineral constituent of hard tissue, making up
93% of human bone with stoichiometric Ca/P ratio of 1.667. It is widely used in medical applications
such as tissue engineering, drug delivery and bone tissue repair. Nowadays, to enhance
biocompatibility of the metallic implants, mostly based on titanium, the surface modification by
deposition of bioactive and biocompatible HAP coatings has been proposed. The electrophoretic
deposition (EPD) is a versatile and cost-effective technique for fabricating advanced HAP coatings.
In this study, in situ synthesis of HAP/TiO2 coating on titanium was prepared on titanium substrates
via anaphoretic EPD of HAP and simultaneous anodization of Ti to strengthen the biocompatible
composite coating. The prepared coatings were characterized using optical miscroscope, scanning
electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. It was found
that controlling the depositi...on conditions it is possible to obtain HAP/anodized titanium dioxide
coatings of variable thickness and porosity. Since smaller size HAP crystals with highly porous
structure shows very high binding ability to various biomolecules, our coating is of excellent coverage
and compactness. The obtained coating appears promising candidate for further biomedical
applications with appropriate morphology for adhesion of osteoblasts.
