摘要: Nanostructures have attracted increasing interest in modern development of hard coatings for wear-resistant applications. In plasma-assisted vapor deposited thin films, nanostructures can evolve during growth or a post-deposition annealing treatment. this review we demonstrate, using TiB 2.4 , TiN-TiB 2 Ti 0.34 Al 0.66 N, and Ti(N,B) as model-coatings, the its influence on mechanical properties ceramic films. For two-dimensional three-dimensional nanostructure, respectively, organizes itself by segregation driven processes. Growth N results formation supersaturated TiN based phase, which tends to decompose into stable constituents via nm-sized domains. As hardness material is determined resistance bond distortion dislocation motion, depend amount constitution obstacles provided, there direct relation between nanostructure.
