In recent years, the importance of energy-saving technologies has increased in response to environmental issues such as global warming and resource depletion. In this study, nanodiamond (ND) and graphene powder (GP) were combined with hydrogenated amorphous carbon (a-C:H) films to improve their tribological properties under dry and water-lubricated conditions. Under dry lubrication at 120 °C, GP addition achieved a low friction coefficient of 0.05, while under water lubrication, highly concentrated ND-dispersed water enabled an ultralow friction coefficient below 0.05. These results demonstrate that the appropriate selection of carbon nanomaterials according to the operating environment is an effective approach for reducing friction in DLC films.
