| Abstract | Due to severe operating conditions and long lifetime requirements for mechanical components, the great challenge is to develop coatingswith anti-wear and high load support capability. The designs for nanocomposite protective coatings are very promising and provide an attractive alternative to take into account the multilayer architecture. In thiswork, a-C(Al)-basednc-TiC/a-C(Al), nc-CrC/a-C(Al) andnc-WC/a-C(Al)nanocompositeswere constructed by Cr/CrN/CrCN multilayer. The microstructure, mechanical properties, friction and wear behaviors for thesemultilayer coatingswere systemically investigated. Results showed that the top-layered nc-TiC/a-C(Al), nc-CrC/a-C(Al) and nc-WC/a-C(Al) nanocomposites were dominated by typically nanocrystallite/amorphous microstructure, and these nanocomposites constructed by multilayer approach presented superior mechanical properties which possessed relatively high hardness, low internal stress as well as high adhesion strength. Particularly, the as-fabricated nc-TiC/a-C(Al), nc-CrC/a-C(Al) and nc-WC/a-C(Al) multilayer coatings exhibited superior anti-wear capability under relatively high appliedHertzian contact pressure compared to corresponding monolayer coatings. The improvement in friction andwear performances of as-fabricatedmultilayer coatingswas mainly attributed to superior mechanical properties and formation of graphitized tribofilm as well as high load support capability by multilayer architecture, indicating that these coatings might be good candidates as solid lubrication materials in engineering applications. |
