Description

For production of stable protectors against thermal and chemical influence, we introduce the technology of their spraying on technological surface. Everybody knows that metallic compounds are combustible. This fuel produces the flame of plasma. The processes of oxidation, which take place of burning chamber, are directed to the creation of ideal mixtures for oxy-ionic gases. In the gaseous phase, the constituents react and build the initial compounds for condensation on coated details. The duration of thermal treatment for our agglomerates could be prolonged with discharge of voltage capacitor. The plasma is super conductor and used as working body for generating of energy and formation of electric arc, which is the area of increased temperature and pressure.
Let us regard a generator of plasma. It is the short circuit between aluminum electrodes in the environment of combustion gases, ionized with thallic and ferric oxy-substances. We calculate static pressure in correspondence with the term for burning temperature at a constant volume. There is the point of equality of thermodynamic functions for components and phases at minimum of Gibbs energy. It becomes higher and the reaction products are moving in the direction to a surface, which is prepared for covering. The acceleration of plasma propulsion is succeeded with dynamic pressure of streaming fluids, which are executed with Lorentz force after impulse of electric current.
In the conditions of high pressures for our ionized conglomerates, we expect an invention of new modifications for the routine compounds after the technological collision with defended surfaces, the crystal cells of which introduce the closed packed symmetries. In this extreme state of matter, we combine Tl-Fe-Al-O-gaseous quantities of the complex polymers with opportunity of preparation for homogeneous compositions of the stoichiometric oxides and the precise mixtures for condensation of crystal structures.
