Fedorenkova L. Mechanisms of saturation of metals and alloys in nonequilibrium conditions of electrolyte plasma with increased heating and cooling rates.

The object of research is a physical regularities of the influence of electrolysis conditions and composition and state of the near-cathode layer, alloy composition on the structure and properties of the diffusion layer is formed on the surfaces of metals and alloys. The aim of research is a the of physical laws and new opportunities for the process of saturation of metals and alloys using electrolytic heating. The methods of research are standard research methods (XRD, MRSA, metallographic, spectral analyzes, corrosion tests, mechanical and magnetic tests, etc.). The determination of the coherent scattering regions of boride crystallites was carried out by the Selyakov-Scherer method; calculations of the diffusion coefficient for the layer depth were carried out using the Grube method. The theoretical and practical results are physical mechanism of the saturation of the metals and alloys surface in the nonequilibrium conditions of electrolyte plasma was developed, taking into account of the cathode layer structure, the mechanism and kinetics of diffuse processes under the action of a local temperature were established, a new method for obtaining diffusion layers on aluminum and its alloys under conditions of electrolyte plasma with high physical characteristics, which include nanoscale inclusions of aluminum borides. The field of use is the results of the research can be used in the development of multicomponent coatings with high physical and mechanical characteristics, increased corrosion resistance, the ability to absorb radiation, thermal stability.
