A new method of preparation of biomaterial composite coating by the technique of subsonic thermal sprayingwas discussed in this paper. Ti6A14V and pure Ti were chosen as substrate and sublayer material respectively and the work-ing layer was sprayed with biomaterial hydroxyapatite (HAP), forming the composite coating. The experiments of heatshock and tensile strength showed that the bonding strength between coating and substrate is almost as same as that of spe-cimen in which Ni/Al powder was adopted as sublayer. The phases of TiN, TiO2, and Ti2O3 were formed in the sublayer,which are free of toxic and have no side effects. The powder of working layer HAP was decomposed partly during spraying,but it can be solved by later treatment.
