The nano-structured hydroxyapatite (HA) coating decreases the fixation time of the bone substitute implant in the host tissue by accelerating the osteoconduction and osteoinduction processes. In this study, the sol-gel derived HA coating was applied on the Ti-6Al-4V alloy substrate. By employing the FTIR, XRD and STA tests on the obtained powder, a suitable heat treatment cycle was determined to achieve a stable and pure nanocrystalline HA coating. The SEM and AFM images showed that the HA coating has cauliflower morphology with nanometric dimensions. The XRF test suggested the selected heat treatment cycle resulted in a high purity HA and a Ca/P molar ratio close to a stoichiometric value of 1.67.
