| 中文摘要 | Owing to the requirements of the stable oper- ation for mechanical components, the urgent challenges are to control tribological moisture sensitivity of protective coatings. In this letter, a-C:Si and a-C:Si:Al carbon-based coatings were successfully fabricated via magnetron sput- tering Si, Al, and C. The microstructure, mechanical properties, and tribological moisture sensitivity of as- fabricated carbon-based coatings were comparatively investigated. Results showed that the as-fabricated a-C:Si and a-C:Si:Al coatings were dominated by typical amor- phous structure. The co-introduction of Al could effec- tively relax internal stress and improve adhesive strength as well as maintain the moderately high hardness for the as- fabricated coating. The striking improvement in tribologi- cal moisture sensitivity of a-C:Si:Al carbon-based coating was mainly attributed to the superior mechanical properties and the formation of continuously compacted graphitized tribofilm under low relative humidity condition as well as low shear strength colloidal silica tribofilm under high relative humidity condition. The good balance between the hardness and toughness, low internal stress, and superior low tribological moisture sensitivity of a-C:Si:Al coating make it a good candidate for solid lubricating coating in engineering applications. |
