Abstract

Solidificatioin of hydroxyapatite (HA:Ca10(PO4) 6(OH)2), and its bonding with titanium (Ti) was achieved simultaneously by using a hydrothermal hot-pressing (HHP) method with no special surface treatment of the Ti. In this study, the relationship between the HA/Ti bonding properties and the the HHP processing temperature is examined. Mixed powders of calcium hydrogen phosphate dehydrate and calcium hydroxide were used as the starting material for the HA ceramics. The powder mixture and the Ti disk were put into an autoclave for the HHP process. The applied pressure was maintained at 40 MPa. The autoclave was heated up to 373 - 573K at a heating rate of 10K/min., and then the temperature was held constant for 2 hours. The optimal operating temperature was 423K. The bonding of HA to Ti was not achieved at temperatures over 423K.
