PLASMA SOURCE WITH A HOT FILAMENT "PINK"

A dense homogeneous plasma generated by a non self-sustained low-pressure arc discharge with a hot W-filament is used to intensify and stabilize technological processes of ion-plasma deposition of functional coatings on materials and articles.

Plasma source with a hot filament "PINK"

Parameters:
Discharge current	10—100 A
Discharge voltage	40—60 V
Operating pressure	0.05—1 Pa
Plasma density	10⁹—10¹⁰ cm^-3
Size	ø300—500 mm

Plasma source "PINK" could be used both independently for producing dense homogeneous plasma in big vacuum volumes and for modernization of industrial technological setups with the purpose of realization of complex technologies of surface treatment of materials, that essentially expands technological abilities of serial equipment and accordingly nomenclature of treated articles.

Fields of application:

Aerospace industry.
Motor industry.
Gas-and-oil producing and processing industries.
Instrumental industry.
and also other industries where technologies of hardening and surface protection of materials and articles are required.

The use of "PINK" allows:

To provide a high-energy efficiency of low-temperature bulk plasma generation;
To reduce a microdroplet fraction in plasma flow of the vacuum arc evaporators;
To produce a plasma cleaning, etching and activation of a surface without its contamination by cathode materials;
To realize complex treatment of articles in a single vacuum cycle including a final cleaning, activation, electron-ion-plasma nitriding of a surface and plasma-assisted deposition of functional coatings;
To provide formation of micro- and nanostructured coatings possessing high hardness (up to 30 GPa), increased (up to 2-3 times) wear-resistance, improved corrosion resistance and attractive appearance.
