Benefits RF power coupling produces cleaner plasmas and ion implants. RF power sources available commercially, is easily controlled, and does not need expensive electronics. Even implant of ions on irregularly-shaped objects allows plasma processing of complex objects such as engine blocks. Works with a wide variety of corrosive gases, including O2 and corrosive BF3. Coating is non-reactive and lasts at least ten times as long as filament sources.
Coating is much more cost-effective.
Porcelain coating technique works on antennas from centimeters to a meter in diameter. Licensing options are available for the manufacture and distribution of this technology for specific and general applications.
