Abstract

Objective To improve the antibacterial properties of medical titanium alloys. Methods Ti-Cu-N films were deposited on Ti6Al4V substrates by magnetron sputtering. The antibacterial analyses employed the fluorescence staining method and bacterial-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.
