Abstract

A hydroxyapatite coating with nano-structure on the roughened titanium surface was prepared by electrophoretic deposition process. To decrease sintering temperature the HAp nanoparticles synthesizedby a wet chemical method was used. It is observed that the coating is uniform without cracks. After sintering the nano-strueture of HAp coating remains unchanged. The surface treatment of Ti is applied to form a distribution of small pits and TiO_2thin layer that improve the adhesion of coatingto Ti substrate. It is shown that the bonding strength of coating is as high as 18±2.5MPa. The hardness and Young's modulus are 40.6 and 0.42 GPa, respectively.
