Objective To improve the antibacterial properties of medical titanium alloys. Methods Ti-Cu-N films were deposi-ted on Ti6Al4V substrates by magnetron sputtering. The antibacterial analyses employed the fluorescence staining method and bac-terial-viability tests on agar plates. The microstructure and the chemical composition were characterized using scanning electron microscope (SEM), X-ray diffraction (XRD) and glow discharge optical emission spectroscope (GDOES) technique. Results The Ti-Cu-N coating exhibited excellent antibacterial properties against Escherichia coli. Conclusion The Ti-Cu-N coating prepared could greatly improve the antimicrobial properties of the Ti6Al4V alloy.
