The aim of the present work was to develop well-adhered and uniform hydroxyapatite-zinc coatings on titanium metal substrate, through an in vitro electro-chemical deposition method. The coating was characterized for functional chemical group, surface morphology, surface chemical analysis, surface roughness, and coat adhesive bonding by Fourier transform infrared spectrometer (FT-IR), scanning electron microscope (SEM), energy dispersive spectroscope (EDS), profilometer, and tape adhesive test respectively.
