Tailoring the interfacial adhesion of anodised TiO2 nanotubes on Ti-6Al-4V alloy for medical implants

Abstract

Self-assembled nano-structure on the surface of bone/dental implants has attracted significant interest in the last few decades. In this context, anodic TiO2 nanotubes have been shown to have a beneficial effect on osteoblast differentiation and bone formation around implant [1-2]. However, there is uncertainty about the interfacial adhesion to substrate as a surface coating for medical implants [3]. In this study, the effects of anodising conditions on the morphology, composition and interfacial adhesion of the nanotubes grown on titanium alloy were investigated with various electrolytes, pH values and voltage seep rate.
