Generation of Surface-Treating Plasma by a Superadiabatic Compression Ballistic Plasmatron

Abstract

The concept of fast high-temperature surface processing (FHTSP) different materials by using compressed homogeneous dense plasma, produced by superadiabatic gas compression in a ballistic plasmatron (BP), is developed. The theory of the superadiabatic compression BP was developed and the experimental installation was created. It is shown that dense plasma can be generated with unique parameters: the temperature more than 10000 K under the compression pressure up to 1000 atm. This plasma is capable of emitting the powerful radiation flux providing the surface energy density up to 80 J/cm 2 . This radiation flux can be used for surface treatment. The advantages of new technology are discussed.
