The commercially pure Ti (cp-Ti) were blasted with Al_2O_3 grit blasting and HAp/Ti mixed powders at room temperature using sand and wet blasting machine. Then plasma spraying with Ti powder or HAp/Ti mixed powder was carried out as bond coat layers. The hydroxyapatite top coat was sprayed with 100μm thickness, subsequently. The cross-sectional observations of those coating layers exhibited unclear interface region between two coating layers. The XRD patterns of the as-sprayed double layers coating were mainly composed of HAp, Ti, and TiO_2 as minor components. EDS analysis also showed the co-existed of HAp and Ti at the HT intermediate layer. The higher bonding strength of HAp top coating layer was expected to result from the unclear interface of the two coating layers.
