Abstract
Hydroxyapatite(HA) film was prepared on stainless steel(SUS316L) plate using radio-frequency magnetron sputtering and treated by the hydrothermal method. The hydrothermal treated HA film was characterized by an X-ray diflractometer(XRD) and a scanning electron microscope(SEM). Adhesion test of HA film performed pullout test. Adsorption of albumin on HA film was measured. The XRD results showed high crystallinity. The crystal growth of HA was observed by a SEM. Adhesion test results of HA film indicated that bond strength of HA film was improved by the hydrothermal method. Adsorbed albumin on HA film increased with hydrothermal treatment times.
