VACUUM ARC COATING FACILITY (VACF)

The vacuum arc coating facility is intended for deposition of functional (wear-resistant, anti-corrosive, heat-resistant, anti-friction, anti-emission, protective, etc.) coatings on large-size products (tubes, sheets, antennas, etc.). The facility provides vacuum pumping, heating and finishing ion cleaning of deposited products, production of gas medium required for technological deposition processes, deposition of coatings on three types of products:

– tubes 1 m - 3 m in length, 10 - 60 mm in diameter, with a maximum loading of 40 pieces; ¬

– sheets 2 m x 1 m in dimensions, with a maximum loading of 5 pieces; ¬

– antennas up to 2 m in diameter.
