Hydroxyapatite (HA) was coated onto titanium substrates using radio frequency sputtering, and the as-sputtered films were placed under hydrothermal conditions in distilled water solutions at pH 5.0, 7.0 and 9.0 and 110°C. The crystallinity, the Ca/P ratio, thickness, and the surface of the films were observed using XRD, EDS, and SEM, respectively.
