The article presents the results of a study for gear transmission on parallel axes with gear axoids and wheels in the form of truncated cones (KZPt). The tangential gear teeth and KZPt wheels in the longitudinal direction coincide with the conical helical lines lying on the truncated cones, which are the axes of the KZPt. In this case, the angle of these cones is invariant with respect to the transfer value of the KZPt, which allows them to vary widely. The length of the KZPt teeth is determined, the growth of which will lead to a decrease in bending and contact stresses in the teeth of the KZPt. As a result, there will be an increase in the load capacity of the KZPt in comparison with a cylindrical gear transmission with chevron teeth (ZZPsh) with the same dimensions according to the basic criteria for the performance of this type of transmission - bending and contact fatigue strength. For the practical calculation of the KZPt, an enlarged scheme of the algorithm for calculating the KZPt is proposed, with reference to the current calculation procedure for the ZZPsh. The design features of the KZPt are noted

A study of the process of high-speed consolidation of powder materials with the simultaneous formation of a welded joint with the surface of the metal base is presented. Thermal and power effects are used as a result of passing the current pulse through the powder composition and the inductor. The electric circuit of the gradual connection of the processing zone and the magnetic hammer, consisting of a flat inductor and a pusher, is proposed. The electric impulse welding-pressing device (EIWP) is connected to a impulse current generator (ICG) with a capacitive energy storage. Impulse currents of 200 - 300 kA allow to obtain Joule heat, warming up the composition to pre-melting temperatures (0,6-0,8) T m , and magnetic pressure of 500∙10 6 N/mm 2 during the process (100-200)∙10 -6 s. The equipment with energy consumption up to 10 kJ with a discharge frequency of 5 kHz is used. The study of the connection zone showed that the welding of the composition with monolithic materials occurs in the solid phase, new structures are not formed. The implemention of a monolithic material in the form of a wire into the pressing zone allows to obtain a connection of dissimilar materials keeping the original structure. In this case, the powder composition is a connecting element. Thus, copper compounds with steel, aluminum, brass and other materials are obtained. The dependences of the strength of compounds on the discharge energy of ICG are obtained

The paper presents the results of investigations of welded joints made of 32G2 and 30HGSA steels made by rotational friction welding on a Thompson 60 welding machine. The structure is analyzed in the initial state and after various temperature modes of heating. The results of the hardness measurement in various zones of the welded joint are given, the results of the tensile and toughness tests are presented. The features of phase transformations occurring in welded materials during welding and subsequent heating at different temperatures, which affect the degree of mechanical inhomogeneity and the level of mechanical properties are shown. It is shown that the integral mechanical properties of a welded joint of 32G2-30HGSA steels during a tensile test are determined by the properties of the zone of thermomechanical influence or induction heating of 32G2 steel, as the least durable area in which deformation is localized and subsequent destruction. On the basis of the studies carried out, the optimal temperature annealing regime is recommended from the position of equal strength and reliability of the structure.

The paper deals with the problem of studying the influence of the parameters of laser processing of a metal surface on the formation of a color gamut in the zone of influence of a laser beam. Prospects for the use of laser marking and engraving the surface of metal products can be significantly expanded due to the possibility of controlling the color of the applied image. The aim of the work is to determine the parameters of laser treatment of a metal surface to create a controlled formation of color images. The ex- periments were performed on a setup based on a pulsed ytterbium fiber laser. During the experiment, it was revealed under what parameters a particular color is achieved. The main drawback that limits the wider use of the laser color marking method is the lack of predictability of the resulting color processing, which implies the need for further research and experiments. Obviously, in order to study the formation of color should be selected the main characteristics of the laser. Experiment planning methods can be used to optimize labeling modes. The difficulty lies in the fact that for each steel grade, it is necessary to select its most optimal marking regimes.

The processes of interaction of exogenous nanoparticles Al 2 O 3 and MgAl 2 O 4 with iron melts containing surfactant-copper have been studied. Thermodynamic calculations confirmed the choice of these nanoparticles. The dependence of the degree of copper removal during heterophase interaction on size factors was studied: the time of isothermal holding after nanoparticle introduction, the type of nanoparticles, and the concentration of copper in the metal. It was shown that the introduction of Al 2 O 3 nanoparticles led to a decrease in the copper content from 9 to 20 rel. %, and MgAl 2 O 4 - from 10 to 24 rel. %. After the introduction of Al 2 O 3 into stainless steel, the degree of copper removal was from 6 to 23 rel. %, depending on the holding time of nanoparticles in the melt and their concentration.

The paper presents the results of testing the technique for obtaining Al-substituted strontium hexaferrite SrFe 12-x Al x O 19 by spontaneous crystallization method. Using the scanning electron microscope JEOL JSM7001F equipped with an energy dispersive X-ray fluorescence analyzer INCA X-max 80 (Oxford Instruments), the chemical composition of the samples was established: for SrFe 12 O 19 – 61,54%O, 35,53%Fe, 2,93%Sr; for SrFe 12-0,67 Al 0,67 O 19 – 61,99%O, 33,27%Fe, 2,76%Sr, 1,98%Al. A uniform distribution of iron, strontium and aluminum ions was detected. It was found that the samples obtained are monophasic. The crystal structure was studied by X-ray phase analysis using a Rigaku Ultima IV diffractometer.

Agglomeration of the bed materials is one of the significant problems in the biomass fluidized bed combustion, especially for agricultural waste with a very high content of sodium and potassium oxides in the ash, which can form fusible eutectic with silicon oxides. The study of the agglomeration conditions of the bed materials for four types of biomass was carried out. The influence of temperature on the proportion of formed agglomerates was established. It is shown that at concentrations of alkaline elements in the bed (more than 0.4 %) agglomeration occurs even at low temperatures of 750-800 o C. Replacement of sand (part of sand) with iron oxides leads to a sharp decrease in the proportion of formed agglomerates even under conditions of potassium and sodium concentration of more than 1 %. The microstructure and chemical composition of agglomerated particles were studied using a scanning electron microscope equipped with an energy dispersive microanalysis system. New data on the structure of the surface layer of agglomerated particles are obtained.

Analytically, on the basis of the differential equations of material balance, the equations of working lines and mass transfer in the distillation column for binary mixtures for the strengthening and exhaustive parts of the packed distillation column with a diffusion structure of the flow in a continuous liquid phase are derived. Comparative examples of the calculation for typical structures of the flow of ideal displacement are given using the derived equations that take into account the longitudinal diffusion for a “ethanol – ethyl alcohol” binary mixture. A calculation algorithm is proposed and technological and geometrical parameters are compared with similar parameters of the same column, calculated according to a typical algorithm, when the dispersed gas phase has the structure of an ideal displacement flow, and the continuous liquid phase is an ideal mixing. The scheme of material flows and their concentrations is presented in the exhaustive part of the rectification column taking into account the longitudinal diffusion.
