摘要：
Carbon films were synthesized on biomedical 316L stainless steel through twinned microwave ECR plasma source enhanced magnetron sputtering system. Visible Raman spectra show the films are typical amorphous DLC films. By measuring the static contact angles with the sessile-drop method, the wettability of DLC films was characterized. The surface energy of the DLC film is 40mN/m or so, and the polar component of surface tension is greater than the dispersive p art, which is hydrophobic. The fact indicates that the solutions with strong acidic and alkali properties, exert a weak destructive action on DLC films. The surface energy of DLC films is dependent on the carbon bonds and surface roughness.
