| Description |
Nanostructured coatings of (Ti-Zr-Hf-V-Nb)N were obtained by the Cathodic Arc Vapor Deposition (CAVD) method. To investigate these coatings, a number of complementary methods of elemental and structural analysis were used, namely, slow positron beam (SPB), proton microbeam (PIXE),micro- and nanoelectron beam(EDS and SEManalyses), and X-ray difraction method (XRD), including method of ““alpha-sin2ψ” measurement of a stress-strain state (X-ray strain measurement). Additionally, the texture of coatings before and ater annealing up to 873K (for time of annealing �= 30min) was also investigated. It was shown that increasing of stress-strain state in the coating during deposition increases the resistance to oxidation at high temperatures of annealing. It was also found that the redistribution of elements and defects, as well as their alignment (segregation), appeared due to thermally stimulated difusion. It is also connected with the process of spinodal segregation near grain boundaries and interfaces around the grains and subgrains.
