Abstract

Abstract: HA/BG composite films have been deposited on Ti-6Al-4V by pulse laser under O2 atmosphere, and EPMA-EDS, SEM, XRD, FTIR measurements have been performed. Under O2 atmosphere, the crystallinity of the deposited films increases and Ca/P atomic ratio slightly decreases with increasing the substrate temperature. When the film was deposited at 600 °C, the film was compact and crystalline HA was observed. Comparing with Ar atmosphere, O2 atmosphere is benefical for decreasing Ca/P atomic ratio of the films, and the in vivo test indicates that the film obtained under O2 atmosphere has excellent osteoinductivity. So O2 atmosphere is a promise alternative atmosphere to fabricate HA/BG composite films by pulsed laser deposition.
