英文摘要	In this study, a new synergy lubricating system was designed by combining the surface texture and film deposition technology to improve the tribological performances of amorphous hydrogenated carbon (a-C:H) films in a ball-on-disk tribometer under vacuum conditions. Tribological behaviours of the untextured and textured films in a vacuum environment were investigated in detail. The results suggest that the wear life of a-C:H film is dramatically prolonged by surface texture with appropriate interval distances. A comprehensive friction and wear mechanism model is proposed based on substantial structural characterization and wear trace analyses. In this model, the generation of the hard and brittle wear debris is considered as the key unfavourable factor resulting in the rapid failure of a-C:H films, while the surface texture is beneficial in reducing the formation of wear debris, and further trapping it during the friction process.
