Tóm tắt

Hydroxyapatite coatings on Ti6Al4V substrates were prepared by a sol–gel method, and characterized by X‐ray diffraction, scanning electron microscopy, and infrared reflection spectroscopy. The coatings obtained at 500°C in air had a hydroxyapatite phase, some of which was carbonated hydroxyapatite, and had a dense and smooth morphology. When the coatings were treated in a simulated body fluid, the coatings had an increase in large hydroxyapatite grains, and a rough and porous morphology. The adhesive strength of the coatings was more than 14 MPa.
