Abstract

© 2022 Elsevier LtdIn this study, undoped, boron doped and graphene oxide doped TiO2 nanotubes (TNT) were synthesized on Cp-Ti (commercially pure titanium) samples. The aim of this research is to investigate the structural properties, surface wettability, corrosion resistance and tribocorrosion behavior of boron and graphene oxide doped TNT. XRD, Micro-Raman, XPS, SEM and a surface tension meter were used to characterize the nanotubes. It was found that the increasing surface roughness and contact area of the synthesized nanotubes improved the surface wettability. By preventing the SBF liquid from reaching the substrate material, the anodic films formed in all TNT-synthesized samples improved the corrosion resistance. The ceramic TiO2 structure formed on the surface increased the surface hardness and consequently, wear resistance improved. The best tribocorrosion resistance was obtained from the graphene oxide doped TNT, which has the longest tubular architecture.
