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.

“…Performance of metal parts often depends upon the quality characteristics of the surface layer. Different technologies are applied to change phase composition and structure of this layer, including, for example, elasto-plastic deformation [1], and treatment of the surface using different types of pulsed plasmatrons [2][3][4], and hardening of the surface using electro-acoustic sputtering [5], and using different types of laser devices for treatment of the surface [6][7].…”

“…Electric energy is used in the majority of the pulsed plasma devices, and they differ only in design characteristics, e.g. electric-discharge compressor [4] and electromagnetic accelerator [2], whereas devices using the kinetic energy of a metal piston have fundamental differences [3]. Adiabatic compression of gas in such a device imparts it a corresponding temperature and pressure.…”

Structuring of surfaces of metal parts is performed with the electric current commutated by the pulsed plasma. Alloying elements are added to plasma and participate in a micro metallurgical process occurring on the molten surface of a part. Heat capacity of metal of the part provides the high rates of cooling and solidification of the melt. Cycling of the melting and solidification process under conditions of pulsed physical fields provides stirring and crystallisation of alloy to form microcrystalline structures. The technology is implemented using ingenious accelerators of alloying elements, which are based on development of the non-stationary processes of detonation of combustible gas mixtures in the electric field. The surface is treated with the pulsed, electric, magnetic, acoustic and elastic-deformation fields, thus enhancing the "abnormal" heat and mass transfer processes and providing formation of new materials and alloys with microcrystalline structures in surface layer.
