Abstract

In this study, synthesis of hydroxyapatite (HA) coatings on Ti6Al4V substrates by biomimetic technique was investigated. In this context, thin and continuous HA coatings were first deposited onto Ti6Al4V implant plates by immersion in 1, 1.5 and 3 times concentrated simulated body fluid (SBF) at 37 °C for different times at pH=7.4. The HA layers were formed in the range of 6 and 19 μm thick. The obtained coatings were characterized by XRD, optical microscope, SEM, surface roughness and microhardness machines. The experimental results clearly show that the biomimetic approach has coated them with HA globular crystals having various diameters. It was found that the coating structure was affected by solution concentration.
