Abstract HA/45S5 composite films were deposited by a KrF excimer laser on Ti-6Al-4 V, and a post annealing was carried out. HA/45S5 composite film deposited at 200 °C is amorphous, and the post annealing can’t promote the crystallization of 45S5 bioglass but can increase the crystallinity of HA greatly. The composition of the composite films and the annealing process play an important role on the formation of the oriented HA. Slight a-axis preferred orientation of HA structure was observed in the films treated at 700 °C for 2 h, and c-axis preferred orientation of HA structure was observed at 800 °C for 2 h or 4 h.
