Plasma electron sources and cathode-ray installations for engineering
Competitive advantages:
- increased resource by 5-10 times
- improved performance
- design simplicity and the absence of expensive and rare metals
Performance
- Accelerating voltage, 10...30 kW
- Beam current; up to 0,5 A
- Beam diameter: - focused, 05... 1 mm - broad, up to 180 mm
- Operating pressure, 10-3...10-5 mmHg
- The depth of welding penetration (depending on the beam power) is 0.8-10 mm
- Depth of hardening (depending on the surface area) is up to 1 mm
Source description
The sources contain a low-temperature plasma generator based on low-voltage discharge with a cold hollow cathode, (hollow anode for broad beams forming) electrode accelerating and focusing systems. As a power supply system, a power supply system for technological cathode-ray installations with hot cathode guns can be used when replacing the cathode glow block in them with a discharge power supply unit, which does not cause significant difficulties.
Application
Instrument and mechanical engineering In the Republic of Belarus - gear welding, in Russian Federation - electron beam welding installations, coatings, liquid, and solid-state hardening, composite material sintering.
Patent protection
The construction of the plasma electron source is protected by the patents of the Republic of Belarus.
Suggestions
- development and transfer of a set of engineering documents for sources and a discharge power supply unit
- shipping, installation, and adjustment of the sources at the customer's plant
- Co-production of installations based on the proposed plasma electron sources
