Abstract

Nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. Hydroxyapatite (Ca10 (PO4)6(OH)2, HA) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. Firstly, Ti-6Al-4V alloy was synthesized by mechanical alloy method with high energy ball milling plantery, HEBM. And then in this work began with preparing hydroxyapatite, HA, from bovine bones and continued with composite in nano clay powder .At the end a hydroxyapatite–clay (HA/Clay) nanocomposite ceramic, 80 wt.% of HA and 20 wt.% nano clay powder, was synthesized through a mechanical method , HEBM. The ability of apatite formation on the produced nanocomposite samples, as a yardstick for evaluation of the bioactivity, was estimated by using simulated body fluid. According to the results obtained mechanical and density values and bioactivity behavior, the sample containing 20 wt. % HA/Clay indicated the optimal properties in mechanical and bioactivity behavior. In fact, this nano composite sample, Ti-6Al-4V/20 HA-clay, is good candidate for medical purposes, bone tissue applications.
