Abstract

Hydrogen peroxide (H2O2), which is produced during inflammation directly after the insertion of an implant, accelerates the corrosion process of Ti-based materials such as nanocrystalline bulk titanium. For this reason, there is a need to provide additional corrosion protection in the initial period following implantation. Coatings based on chitosan/bioactive glass were obtained by electrophoretic deposition (EPD) on nanocrystalline Ti. Results indicated that homogeneous, crack-free composite chitosan/bioactive glass EPD coatings effectively increased the resistance of nanocrystalline titanium to dissolution induced by H2O2.
