A Study on the Deposition of Hydroxyapatite Nano Thin Films Fabricated by Radio-Frequency Magnetron Sputtering for Biomedical Applications.

We have developed a HA nano-coating technology suitable for dental and orthopedic implants using RF magnetron sputtering method which can achieve excellent adhesion to titanium compared with other various PVD coating technologies. As a result, the HA thin film prepared by RF magnetron sputtering has a thickness of about 1.6 [μm] and its adhesion force to base metal is about 11.93 [N] or more and Ca/P ratio is about 1.64, which is suitable for dental and orthopedic implants.
