Abstract

It was attempted to implant hydroxyapatite granules into a superplastic Ti-4.5Al-3V-2Fe-2Mo-alloy substrate. In order to improve the biocompatibilityof the Ti-alloy, a pure titanium film was initially coated on the alloy substrate by reactive direct current (DC) sputtering method. Hydroxyapatite granules with 32-38 mum in diameter were spread over the coated Ti-alloy substrate and then pressed to implant the granules in the substrate. Upon implanting the granules at the temperature of 750 degreesC, many cracks on the coating film were observed centering around the implanted grannies, and theHAp granules themselves were observed to be damaged, too. In the meanwhile, upon implanting the grannies at the temperature of 800 degreesC, a pure titanium coating film was observed to become thin partially at the shoulder of the side wall in the vicinity of HAp granules; however, the grannies were implanted into the alloy smoothly without any crack: at all on the coating film and any damage to the grannies. The hydroxyapatite implanted Ti alloy is expected to be useful for biomaterials as artificial bones and dental roots.
