| 英文摘要 | TiO2 coating has been widely applied in orthopaedic and dental implants owing to its excellent mechanical and biological properties. However, one of the biggest complications of TiO2 coating is implant-associated infections. The aim of this work is to improve the antibacterial activity of plasma-sprayed TiO2 coatings by plasma immersion ion implantation (PIII) using zinc (Zn) ions. Results indicate that the as-sprayed TiO2 coating is mainly composed of rutile phase. Zn-PIII modification does not change the phase compositions and the surface morphologies of TiO2 coatings, while change their hydrophilicity. Zn-implanted TiO2 coatings can inhibit the growth of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), and the ability to inhibit S. aureus is greater than that to E. coli. Zn ion release and reactive oxygen species may be attributed to improving the antibacterial activity of TiO2 coating. Therefore, Zn-PIII TiO2 coatings on titanium suggest promising candidates for orthopaedic and dental implants. |
