The objective of the present manuscript was the synthesis of nano hydroxyapatite (n-HA) and its coating on orthopaedic implant material. The synthesis of n-HA has been achieved using wet chemical method. The elemental analysis and FTIR spectrum confirmed the formation of n-HA having a Ca/P ratio of 1.71. The AFM and XRD results showed the nano dimensions of hydroxyapatite (HA) in the range of 25–35 nm. Scanning electron micrographs (SEM) showed a flake-like structure of n-HA having sharp edges. The n-HA was further coated on orthopaedic implant material (titanium alloy, Ti6Al4V), using the electrostatic spray deposition (EDS) technique. The surface roughness of Ti alloy increased from 2.34 μm to 2.77 μm after coating with n-HA and corrosion resistance improved drastically. XRD pattern of n-HA coated Ti alloy however showed broadening of HA associated peak, reflecting change from crystalline to amorphous phase of n-HA.
