Paper Title:
Crystallization of Sputtered Hydroxyapatite Films by Hydrothermal Technique and Its Cytotoxicity
  Abstract

Hydroxyapatite (HA) was coated onto titanium substrates using radio frequency sputtering, and the coated HA films were crystallized in an autoclave at 110 °C using a low temperature hydrothermal method. The crystallinity, the Ca/P ratio, and the surface of the films were observed using XRD, EDS, and SEM, respectively. From the XRD patterns, a sputtered film after the hydrothermal treatment had crystallized after 24 h, and the Ca/P ratio decreased from 2.43 ± 0.07 to 1.75 ± 0.11. The growth rate of osteoblast cells was used for cell culture. Among control, titanium and hydrothermally treated film, there was no significant difference in the cell growth rate. However, the growth rate was suppressed on the as-sputtered film.
