Complex study of structural state and properties of ion-plasma functional coatings

Abstract

Abstract Based on the justified methodological complex the study of the multilevel structural state of coatings and surface layers created by the ion-plasma modification was made. A comparative quantitative assessment of structural changes and the chemical composition of coatings by SEM, XPS, EDX methods and the physical and mechanical properties of coatings based on titanium nitride was carried out. It was found that for all variants of coating formation there is no titanium in the metallic state and, therefore, the formation of a droplet phase does not occur. Layer-by-layer XPS analysis has determined that coatings are heterogeneous in its composition in depth. It is shown that the modification of steel surfaces with a TiN-based composition can be used to form wear-resistant coatings on the working bodies of road milling machines that are actively used in the overhaul and maintenance of the highways.
