Hydroxyapatite Coating on Alkaline-Treated Titanium Through Electrochemical Deposition
Hydroxyapatite (HA) has been successfully coated on alkaline-treated titanium (NaOH-treated Ti) through an electrochemical method using a solution containing Ca(NO3)2 × 4H2O and NH4H2PO4 at 80°C. Pure Ti substrates were immersed in 5M NaOH solution at 80°C for 24 h. XRD results confi rmed the formation of an HA layer on the surface of the Ti substrates. The SEM result has shown that the structure of the HA layer contains a ribbon-like morphology with a diameter of ~120 nm. HA coating enhanced the hydrophilic properties compared with the surface of bare Ti substrates. Moreover, HA coating showed excellent biocompatibility as demonstrated by cell attachment in vitro at 72 h of culturing, which is a promising coating method of HA on NaOH-treated Ti for titanium implants.
