Abstract
Solidificatioin of hydroxyapatite (HA) and its bonding with titanium (Ti) alloys was achieved simultaneously by using a hydrothermal hot-pressing (HHP) method. The reaction temperature used for the HHP treatment was as low as 150 °C. Two types of Ti alloys; Ti-15Mo-5Zr-3Al and Ti-6Al-2Nb-1Ta were tested to examine the effect of NaOH hydrothermal treatment. The NaOH treatment was shown to be useful to enhance the interface fracture property in the bonded HA/Ti body for both Ti alloys. The use of Ti-15Mo-5Zr-3Al was more effective in the NaOH treatment and the bonded HA/Ti body provided approximately three times higher interface toughness compared with that for the non-treated Ti alloy.
