The article is devoted to the organization of management of the application of wear-resistant materials on the formative tool at set intervals by the method of electro-acoustic spraying. A complex highly concentrated effect of the ultrasonic method in a permanent process, based on the pulse energy, which leads to an increase in the plasticity of the material and is not associated with its heating. The law of electro-plastic deformation for a conducting material, taking into account the high density of the acting amperage in the process of active deformation at a constant rate, considered in this article, establishes a clear dependence of the strengthening of the substrate material. The process of concentration of electromagnetic and thermal fields in a conductive material with defects such as a crack makes it possible to use this technology to slow down the propagation of cracks while reducing the concentration of mechanical stresses.
The article is devoted to the synthesis of multifunctional composite coatings with improved antifriction properties in a complex acoustic field realized by means of two quasi-coherent sources of ultrasonic vibrations. The developed device for acoustic synthesis, which is based on the cavitation effect, allows developing high effective pressure values from 100 to 1000 bar in the shock wave, when the cavitation cavity collapses. The highly concentrated effect of the device on the composition ingredients synthesizes new compounds, are impossible to obtain under ordinary conditions. The process is fully controllable and allows imparting unique properties to the finished product, among which a special place should be given to the variable value of the friction coefficient. It depends on the external load and the high wear resistance value of the surface layer of the multifunctional composite protective coating. There is a problem of improving the energy efficiency of agricultural machinery and equipment. The solution to this problem is associated with the use of innovative technologies based on implementing the highly concentrated energy sources. The aim of the research is to optimize the process of obtaining multifunctional composite coatings with improved antifriction properties based on mass transfer of the electrode material and the subsequent formation of structures with predicted physical and mechanical properties. In order to achieve this goal, a generalized model of applying multifunctional composite coatings using the electro-acoustic spraying method has been developed.
The paper is devoted to the expediency of using ultrasonic treatment in combination with laser hardening for U8, U10, X12M steels and the study of the effect of ultrasonic longitudinal and torsional acoustic vibrations on the intensification of an increase in the concentration of point defects in the crystal structure. The introduction of a longitudinal and torsional ultrasonic field by transforming longitudinal ultrasonic vibrations made it possible to form a highly concentrated effect, which led to an increase in the effects of laser hardening.
The problem of obtaining predicted physical and mechanical properties and a given service life of multifunctional composite protective coatings in the form of barrier layers that increase the service life of mechanical engineering products and formative tools are inherently interconnected. Among all the variety of innovative highly efficient technological processes, a special place should be given to the method of electro-acoustic spraying (ELAN). This method is innovative in the field of synthesis of multifunctional composite coatings, which allows the formation of protective films of an amorphous material on any conductive substrates [1]. This technology is based on the use of the complex energy of an electric spark and a complex ultrasonic field. The aim of this work is to optimize the process of obtaining multifunctional composite protective coatings based on the complex mass transfer of the electrode material and the subsequent formation of amorphous structures with predictable physical and mechanical properties by the method of electro-acoustic spraying based on the effect of electro-plasticity during deformation and pulsed action of a high-energy electromagnetic field.
