摘要：
The commercial Ti-6Al-4V and Al-6Al-7Nb are finding numerous applications as metallic biomaterials because of its biocompatibility and functionality. However, the optimum surface conditions that enhance the bone conductivity of such materials are not well established. The current work aimed and exploring the different surface conditions/treatments which enhance the bon conductivity of such alloys as revealed by the selective precipitation of hydroxyapatite / calcium phosphate compounds on their surface from the simulated body fluid solution. The alloy samples were produced by forging and casting. The surface conditions investigated were the mechanically-polished, furnace oxidized, alkaline-treated surfaces. The results showed that surface oxidation and alkaline treatment highly enhanced the precipitation of hydroxyapatite on the sample surfaces, with evident differences being observed between alloy compositions and production processes. © 2017 The American Ceramic Society.
