Synthesis of the hydroxyapatite coatings on the Ti substrates by mechanical alloying

The hydroxyapatite coatings were deposited by mechanical alloying on Ti substrates using vibratory and planetary ball mills. The structure and morphology of the deposited coatings were analyzed by X-ray diffraction and scanning electron microscopy. The tribological properties and biocompatibility of the deposited coatings were also studied. A relatively high density and adhesion coating were observed for the coating obtained in a vibratory ball mill for powder mixture ratio of hydroxyapatite to α-Ti as 1:1, respectively. The average value of the hemolysis of the obtained coating was about 6.98%, which was statistically significant.
