Double Glow Discharge Phenomenon and Its Applications
The double glow discharge phenomenon has led in the invention of “Double Glow Plasma Surface Alloying Technology”. This technology has overcome the limitation of the plasma nitriding technology which can only use nonmetallic gas elements for surface alloying. This chapter mainly introduces the double glow discharge phenomenon with its discovery, functionalities, discharge modes, and applications. The double glow hollow cathode discharge and its discharge characteristics are also introduced and discussed. The initial set of experimental setup and the result of the double glow plasma surface alloying technology have been described.
