Investigation on antibacterial property of Cu-coating on pure titanium fabricated via plasma surface alloying

摘要

This paper describes the fabrication of a Cu-coating on pure titanium via plasma surface alloying technology. The surface morphology, cross-sectional microstructure and elemental distributions of the coating were analyzed by scanning electron microscope (SEM) and glow discharge optical emission spectroscope (GDOES). The antibacterial property of the Cu-coating was assessed via in vitro bacterial adhesion test. The results showed that the Cu-coating was continuous and compact. The Cu-coating endowed pure titanium with a promising antibacterial property.
