Abstract：In this study,the hydrogenated Ag-containing diamond-like carbon(DLC-Ag)films were prepared by adding acety-lene to the coating atmosphere of magnetron sputtering to inhibit silver precipitation at film surface.The addition effects on the antibac-terial properties of the films were investigated by scanning electron microscope(SEM),EDX,colorimetry and microhardness measure-ment,and agar plate counting antibacterial test.The results showed that when acetylene flow rate was increased,silver precipitation at film surface decreased,blackness increased,and hardness decreased.Even the sample with the lowest silver content(0.8 at%)showed good antibacterial activity against E.coli.
