Multycomponent (Ti-Zr-Hf-V-Nb)N nanostructure coatings fabrication, their properties and structure

摘要

One of the most important tendencies of modern science is creation of new materials, in particular, creation of multycomponent nanocomposite coatings with the grains characteristic dimensions between 2 and 50 nm. Nanocomposite coatings are a new generation of materials. They consist at least of two phases with nanocrystal and/or amorphous structure. Due to small (< 10 nm) grain size and more important role of surrounding boundary zones, nanocomposite materials acts differently and show absolutely different properties in comparison with usual materials (with grain sizes ≥100 nm). Therefore, creation of new nanocomposite (nanostructure) coatings is a topical problem.
