Delta 3 Anode Plasma
The GTV Delta gun is a rugged industrial tool that produces high quality surface engineered coatings. Delta Plasma torch uses 3 anodes with one cathode. This configuration allows for systems in production in industries ranging from:
- IGT
- Printing Rolls
- Paper Rolls
- Steel Mill
- PVD Targets
- Large area spraying of ceramics
- Powder Spherodizing
- Powder Processing
Delta Gun and Coating Features
- 3 Anode, 1Cathode
- Cascading plasma for long arc, high voltage/low current operation
- 1 power supply
- Argon/ Hydrogen plasma gas mixtures (standard)
- Easy to change electrodes
- Fixed anode arc root locations, not depending on plasma gas flow rate and composition or current level
- 3 powder injectors focus into “hot spots” of plasma adjacent to the anode arc root
- Stable Arcs, voltage ± 3 V
- Low wear cathode
- Variable nozzle diameters for parameter optimization
Key Applications
- Thick TBC coatings (2 mm with > 20% porosity)
- Anilox Cr2O3 coatings
- Corona Treater Roll coatings (Al2O3, Al2O3/Cr2O3)
- Y2O3 coatings for semi-conductor tools
- MCrAlY/Al2O3 for steel mill hearth rolls
- Printing machine rolls (Al2O3/TiO2)
- Silicon, ZnO/Al2O3 for solar applications
- Si, Si/Al, TiO2 for PVD targets (Currently under licensed to Heraeus company)
- NiCr bond coats
