The coated HAp films are deposited on Ti substrate by use of the pulsed laser deposition (PLD) method under the different water atmosphere pressure, and are treated by using a post-annealing method under condition of the different annealing temperature. The coated HAp films are characterized using the scanning electron microscopy (SEM), electron probe X-ray microanalysis (EPMA), X-ray diffraction (XRD) and atomic force microscope (AFM). The ratio of Ca to P (Ca/P) in the coated films fabricated under the water pressure of 0.1 Torr is shown a quite high value, and is decreased as the value of water pressure increase. Furthermore, the HAp films treating with an annealing temperature of 400 ℃ are shown high crystallinity.
