- Abstract
- Two variants of a new DC arc plasmatron's design, their assembly drafts and part specifications are presented. The main feature of the new plasmatron is very low anode erosion rate that was measured to be 4 through 5 orders of magnitude lower than the one for conventional devices. Arc Volt-Ampere characteristics, manifestations of the anode spot's diffuse character and technologic gas plasma-chemical activation are considered.
