Abstract: A good Ti-based joint implant should prevent stress shielding and achieve good bioactivity and anti-infection performance.
To meet these requirements, the low-elastic-modulus alloy—Ti–35Nb–2Ta–3Zr—was used as the substrate, and functional
coatings that contained bioceramics and Ag ions were prepared for coating on TiO2 nanotubes (diameter: (80±20) nm and
(150±40) nm) using anodization, deposition, and spin-coating methods. The effects of the bioceramics (nano-β-tricalcium
phosphate, microhydroxyapatite (micro-HA), and meso-CaSiO3) and Ag nanoparticles (size: (50±20) nm) on the antibacterial
activity and the tribocorrosion, corrosion, and early in vitro osteogenic behaviors of the nanotubes were investigated. The
tribocorrosion and corrosion results showed that the wear rate and corrosive rate were highly dependent on the features of the
nanotube surface. Micro-HA showed great wear resistance with a wear rate of (1.26±0.06)×10−3 mm3/(N·m) due to adhesive
and abrasive wear. Meso-CaSiO3 showed enhanced cell adhesion, proliferation, and alkaline phosphatase activity. The coatings
that contained nano-Ag exhibited good antibacterial activity with an antibacterial rate of ≥89.5% against Escherichia coli.
These findings indicate that hybrid coatings may have the potential to accelerate osteogenesis.
