This study presents a novel method for incorporating graphene into diamond-like carbon (DLC) films using pulsed-DC plasma-enhanced chemical vapor deposition (PECVD) with an additional cathode. Unlike conventional PECVD methods, this approach enables direct in-situ incorporation of graphene into the DLC matrix via a glass-tube-assisted pulsed-valve system, ensuring uniform dispersion. The effects of graphene incorporation were examined by varying the glass-tube length. Results show that positioning the tube closer to the substrate holder enhances the DLC-graphene film properties, achieving a maximum hardness of 25.11 GPa and reducing the coefficient of friction to 0.0904. Additionally, a low wear rate of 1.03 x 10- 6 mm3/N & sdot;m was obtained. A scalable single-step method producing uniform, adherent, and wear-resistant DLC-graphene coatings. (AU) | |
