Abstract
In order to develop a biomaterial which has a hopeful bio-activity and a high mechanical strength, we tried to manufacture a composite material of hydroxyapatite(HAp) and titanium (Ti). Mixed powders of HAp and Ti were coated to a surface of Ti rod as a base metal. This composite material was fired by a high-frequency furnace. We observed that a coated layer of a mixture of HAp and Ti was joined closely to a surface of Ti rod. By electron probe microanalysis, we also recognized a density of Ca increased and that of Ti decreased from a contact area to a surface in a coated layer of a mixture of HAp and Ti.
