Different Morphology of Hydroxyapatite Coatings on Titanium by Electrophoretic Deposition
The objective of the present study was to define the optimal conditions and characterizations of hydroxyapatite (HA) coatings on titanium by electrophoretic deposition (EPD). The EPD processing parameters, such as deposition time, HA concentration level in the suspension, and applied voltage are experimentally determined. A good packing, crack-free and uniform HA coating on titanium was prepared. Then the coatings were sintered at 800 °C for 2 h. The sintered coatings presented a very homogeneous polycrystalline structure free of cracks. The results show that the application of EPD is an effective method in obtaining HA coatings with good properties.
