“…The theory of the formation of coating (nuclei) initial phase during the metals crystallization is based on position of the new phase formation in the preparation-solid system. As the zinc coating nucleus, we should understand the crystalline, which consists of the minimum number of atoms necessary to build one unitary crystalline cell [4][5][6][7]. According to Gibbs theory, for the new phase formation, a certain supersaturation of the preparation with respect to the equilibrium value is necessary.…”

“…As the coating grows, small groups of crystals grow along the metal surface. Under the influence of vibrowave and collision of the working medium, micro/nanoparticles of zinc powder, falling into of electric forces action sphere, are simultaneously compacted by it with a growing precipitate, forming a continuous coating [6] (Fig. 2).…”

“…The broad technological capabilities of vibrowave technological systems are the most effective means for obtaining high-quality, from the point of view of ensuring operational properties, coatings for various functional purposes on the surface [1][2][3][4][5][6][7][8][9][10][11][12]. Feature of the coating method considered in the article is that it is formed on the metal surface as a result of shock-pulse interaction of free-moving indenters in a closed volume under the influence of low-frequency oscillations.…”

The control of obtaining the predicted physico-mechanical properties of protective coatings of machine parts in a complex acoustic field by the method of electroacoustic spraying is carried out through the use of highly concentrated sources of electrical energy. The prediction of the physico-mechanical properties of the hardened surface of machine parts is made on the basis of the experiment planning methodology with non-orthogonal planning matrices. The adequacy of the obtained mathematical models was carried out using the criterion of adequacy of Fisher. Physical fundamentals of mass transfer of materials to a substrate in a complex acoustic field, realized through the transformation of longitudinal vibrations, to longitudinal-torsional, have been developed, while the amplitude of oscillation of the acoustic system is 5 to 15 micrometers. The use of longitudinal-torsional ultrasonic waveguides in this process and ultrafast cooling temperatures make it possible to form elements such as carbides, carbonitrides, and intermetallic compounds on the surface of a conductive material. The subsequent impact with a shift against the surface produced by the waveguide - electrode leads to irreversible microplastic deformations of the surface layer, which provide the specified parameters of surface quality and its physico-mechanical properties.
