High-performance rectilinear vacuum-arc cathode plasma source with filtration from particulates

Research area – plasma.

Purpose – for effective coverage of all kinds of surfaces.


– application of various types of coatings:

– wear-resistant coatings with a low coefficient on friction elements of machine parts and mechanisms in the tool industry, mechanical engineering, textile industry, etc .;

– multicomponent wear-resistant coatings based on nitride, carbides, oxides and their mixtures for strengthening precision tools, compressor blades and aircraft engine turbines;

– biologically inert coatings, optically transparent, dielectric, corrosive coatings, chemically inert coatings.

Description. The plasma source implements a configuration of a transporting magnetic field, a system of reflectors and traps for macroparticles, which makes it possible to provide high-quality coatings with a significant increase in the generation of purified plasma flows in comparison with existing filtration systems for vacuum arc plasma.
