Abstract

Biocompatible porous titanium was fabricated by powder sintering. Hydroxyapatite (HA) coating was deposited on surface of porous titanium by treatments of acid alkali and immersion in simulated body fluid in turn. The pre calcification treatment before immersion in SBF was performed to accelerate the HA formation process. The results show that pre calcification assisted biomimetic method is a n effective approach to deposit HA layer. The porous titanium with unique porous structure, proper mechanical property and bioactive HA coating is a promising candidate for hard tissue implant..
