Abstract

Hydroxyapatite (HAp) nanoparticles synthesized by microemulsion technique were coated on Ti6Al4V substrates by electrophoretic deposition (EPD) method in this study. Sodium Dodecyl Sulfate (SDS) surfactant, calcium hydroxide water based solution, benzene organic medium and diluted orthophosphoric acid were used in synthesis of hydroxyapatite nanoparticles. HAp nanoparticles were synthesized in the water microemulsion formed by a rapid mixing process. Synthesized HAp nanoparticles were coated on Ti6Al4V substrates for 5, 10, 15, 20, and 30 minutes by an electrophoretic deposition method, dried slowly in the air environment and sintered 1000 ° C under 10-4 mbar vacuum for 20 minutes. Crystal structure formation of the synthesized hydroxyapatite nanoparticles and coatings were investigated using X-Ray diffraction (XRD). Microstructures of the coatings before and after sintering were examined with a light microscope. In addition, Scanning Electron Microscopy (SEM) investigations showed that the size of the synthesized Hap nanoparticles was in the range of 20-200 nm.
