| Abstract | CrAlN nanocomposite films with various Al contents were prepared by a reactive magnetron sputteringtechnique using Cr and Al targets in the reactive gas mixture. The micro-structure, mechanical properties andtribological behaviors of traditional CrN and newly-fabricated CrAlN nanocomposite films were compared.XRD results showed that single-phase fcc (face-centered cubic) CrAlN films formed a solid solution wherebyCr atoms were substituted by Al atoms. High resolution TEM results demonstrate that the CrAlN filmpossesses a unique amorphous/crystalline nanocomposite micro-structure with ∼5 nm crystalline uniformlyembedded into an amorphous matrix. In addition, CrAlN nanocomposite films exhibited relatively smallergrain size and denser structure when compared with CrN films. All the CrAlN nanocomposite films with thehighest hardness being approximately 33.4 GPa exhibited much higher hardness and better wear resistancethan traditional CrN films The excellent anti-wear performance of CrAlN nanocomposite films can beattributed to an amorphous/crystalline nanocomposite micro-structure and their high hardness. CrAlNnanocomposite films are considered as potential protective surfaces for such kinds of moving parts as gears,cutting tools and shafts used in engine and other mechanical mechanisms. |
