In Situ Tantalum Doping of Titanium Dioxide Nanotubes via Electrochemical Method for Enhanced Mechanical and Biological Properties.

ABSTRACT: Titanium dioxide nanotubes (TNTs) have favorable biocompatibility and nanoscale morphologies, and they have been extensively explored for titanium implant surface modifications. However, they are limited by their mechanical strength and weak interfacial adhesion between the nanotube layer and the titanium substrate. This restricts their clinical applications. In this study, a two-step electrochemical anodization method is developed to achieve in situ tantalum (Ta) doping into TNT arrays to enhance their mechanical performance without altering their nanotubular structure. The surface morphology, element and crystal phase composition, surface roughness, wettability, and mechanical properties of the Ta-doped TNTs were then thoroughly characterized. Scanning electron microscopy revealed that t
