Abstract

Electrophoretic deposition (EPD) was used to prepare hydroxyapatite (HA) coatings on titanium. The influence of suspension pH on the formation of cracks in coatings was studied. Results show that the pH of suspensions plays an important role in the EPD of HA coatings and cracks in the green coatings were minimized at pH 2.9. Biomimetic mineralization and self-assembled collagen were developed to modify the EPD HA coatings for biomaterials improvement. Results show that the surface of HA coatings was modified with a layer of apatite/collagen composite by the combination of self-assembled collagen and biomimetic mineralization.
