Abstract:An experimental set-up was designed for the fabrication of composite coating containg titania and Ag on the surface of titanium and make the titanium has bioactive and antibacterial synchronously. The SEM, XRD, bioactive test and antibacterial test were imployed to researched that how the method of the heat treatment work on the formation and capability of the titania-Ag composite coating. The results show that titanium with titania nanotube arrays diped in the saturated silver nitrate solution and heated under 500癈 or 600癈, the titanium can obtain bioactive and antibacterial synchronously because of the existence of titania-Ag composite coating.
