Study of the influence of the conditions of obtaining and further processing on the structural and surface properties of the film surface. Conducting qualitative and quantitative analysis of nanostructured coatings based on oxynitrides and tantalum oxides. Within the framework of the project's tasks, the development of techniques for the formation of biocompatible nano-structural coatings based on Ta oxides and oxynitrides by modern vacuum-plasma methods and research of these coatings in order to further determine the relationship of biological properties of coatings with their structural, surface and mechanical properties. The microstructure, surface roughness and chemical composition of the coatings Ta, Ta2O5 and two-layer Ta / Ta2O5 were investigated. Quantitative and qualitative analysis of nanostructured coatings based on oxynitrides and tantalum oxides was performed by electron microscopy with X-ray microanalysis (EDX), as well as X-ray (XRD) and photoelectron spectroscopy (XPS) methods.
