Abstract

In ablation controlled capillary discharges, the inner ablating sleeve is usually made of an insulator such as polyethylene or Lexan. There has been almost no use of metals, alloys, or semi-conductor materials in capillary discharges as most of the studies were devoted to the generation of high enthalpy plasma flows using polyethylene as the liner material. The work of Shcolnikov et al. [1995] provided a theoretical study in which the authors proposed using the ET plasma to accelerate powder particles in order to coat substrates and produce coatings with strong adhesion and low porosity.
