Preparation of Hydroxyapatite Coatings by Anodizing-Electrodeposition on Pure Titanium

Abstract

The surface of pure titanium was coarsened by anodizing. Hydroxyapatite (HA) coatings were electrodeposited on the anodized pure titanium in a simulated body fluid. Complementary characterization methods (SEM, XRD, static contact angle, roughness tester, universal testing) were used to investigate the features of the coatings. The results of this study indicate that porous surfaces can be achieved on the pure titanium by anodizing, and the HA coatings show a relatively regular network structure. Moreover, HA coatings exhibit a certain roughness, good wettability and rather high shear strength.
