Thin calcium phosphate coatings on titanium alloy substrates were prepared by Ar+ ion beam assisted deposition (IBAD) from hydroxyl-poly-calcium sodium phosphate (HPPA) target. The coatings were analyzed by XRD, FTIR, XPS. These analyses revealed that the as-deposited films were amorphous or no apparent crystallinity. No distinct absorption band of the hydroxyl group was observed in FTIR, spectra of the coatings but new absorption bands were presented for CO 3 -2 . The calcium to phosphorous ratio of these coatings in different IBAD conditions varied from 0.46 to 3.36.
