NANOSTRUCTURED MULTILAYER COMPOSITE WEAR- AND CORROSION-RESISTANT VACUUM-PLASMA COATINGS

Description of the project: The processes of phase and structure formation of multicomponent systems based on refractory titanium compounds with various alloying additions deposited from separated plasma streams have been investigated. The synergistic effect of the ultradispersed structure of the coatings due to the introduction of alloying elements and the minimum roughness due to a decrease in the amount of the droplet phase in the plasma flow makes it possible to significantly increase the protective properties (corrosion resistance, thermal and wear resistance) of the formed layers. Compliance with the thermophysical and thermodynamic conditions of deposition by optimizing the technological parameters ensures the formation of coatings with high hardness and ultradispersed structure.

Benefits:

The advantages of the proposed technical solutions are as follows: a good combination of adhesion, physical-mechanical and protective properties, which provides an increase in wear resistance, for example, of a tool with coatings 2 or more times as compared to a tool without a coating.

Achieved results: 

Technological processes have been developed for the deposition of multilayer composite coatings on a number of products (non-grindable carbide plates, steel tools, heat-loaded products for various purposes, etc.)
