Calcium hydroxyapatite, HA, (Ca10(PO4)6(OH)2) bioceramics, owing to their similarity with the human bone
and dentin minerals, attract significant interest for orthopaedic and dental applications. Biological apatites, on the other
hand, are carbonate substituted and calcium-deficient. Biomimetic coating of titanium and related alloys with carbonated
apatitic calcium phosphate is an important area of research in implantology. While this paper specifically refers to coating
Ti-6Al-4V, (TAV) the obtained results are valid with other related alloys as well.
An attempt was made in the current research to accelerate the biomimetic coating process through precalcification of the
alkali and heat treated alloy. The precalcification resulted in a homogenous layer of calcium precursors on the surface of
the alloys. Such precursors accelerated the biomimetic deposition of carbonate hydroxyapatite (CHA) coat resembling that
of the biomineral apatite upon soaking in Kukubo corrected simulated body fluid (1.5 x c-SBF). The development of coats
on Ti-6Al-4V surfaces were assessed by step by step diffuse reflectance infra-red spectroscopy and scanning electron microscopy.
The essential information of biodeposition was obtained by following the uptake or release of calcium and inorganic
phosphorus, Ca, iP, ionic species biochemically and mirrored by parallel electrical conductivity measurements of the
