In this study, nano-particle formation of Mn/HA on the Ti-35Ta-xNb alloy by electrochemical methods has researched using various experiments. These alloys were performed by arc-melting furnace and then heat treated for 1000 degrees C at 12 h in Ar gas atmosphere and quenched at 0 degrees C water. Hydroxyapatite precipitation has been synthesized from 5 mM Ca(NO3)(2)center dot 4 H2O+3 mM NH4H2PO4 at 80 +/- 1 degrees C. Manganese doped Hydroxyapatite precipitation has been synthesized from 4.95 mM Ca(NO3)(2)center dot 4 H2O+3 mM NH4H2PO4+0.05 mM MnCl2 center dot 4 H2O at 80 +/- 1 degrees C. Morphology and structure were examined by FE-SEM, EDS and XRD. The microstructure of Ti-35Ta-xNb alloys was transformed from alpha phase to beta phase as Nb content increased. The nano-scale HA shapes were plate-like precipitates and Mn doped HA shapes were net-like precipitates on Ti-35Ta-xNb alloys, and Ca, P and Mn peaks were detected on the Mn/HA deposited surface.
