    In this study, the anti-bacterial performance of modified diamond-like carbon (DLC) coatings with Si and F was investigated and compared with standard DLC coatings and stainless steel using Klebsiella pneumoniae as test bacterium. The experimental results indicated that the F and Si doped DLC coatings reduced the surface energy and improved anti-bacterial ability of DLC coatings. The extended DLVO theory was used to calculate the interaction energy between the coatings and the bacterium. The anti-bacterial mechanism was explained using the extended theory.
