Item type:Item, Mechanism of Formation of Plane Surfaces with an Electric Arc(Allerton Press, Inc., 2019) Bokov, V.; Sisa, O.; Mirzak, V.; ΠΠΎΠΊΠΎΠ², Π. Π.; Π‘ΡΡΠ°, Π. Π€.; ΠΡΡΠ·Π°ΠΊ, Π. Π―.A new method is offered for high-performance dimensional treatment by an electric arc (DTEA) of two similar plane surfaces in the components of hard-for-treatment materials in a bipolar mode without the traditional application of an electrode, which in contrast to the method of DTEA, with the application of an electrode, provides the rise in the efficiency of treatment by 230 %. It is shown that while transfering from the unipolar DTEA of the hard alloy BK-15 by the graphite electrode-tool to the bipolar DTEA of two samples of the same alloy, there is a considerable increase of thermal energy of the cathode area due to the energy of the arc column, which can overrun the thermal energy of the anode area and invoke the inversion, that is, the change of the direction of prevailing electric erosion. This increase of the thermal energy of the cathode area of the arc explains the increase of productivity of the bipolar DTEA of the two samples of the hard alloy BK-15 in contrast to the unipolar one.

Modern methods of electro-erosive dispersion of electrically conductive materials that use non-stationary forms of electrical discharges in fluid have low productivity. That is associated with long pauses of discharges. The objective of this research is to raise the productivity of obtaining metal powders. From a methodological point of view, a metal powder was obtained during in the process of research using an electric arc in the transverse hydrodynamic flow of the working fluid as a product of dispersion of specially prepared work-pieces and as a waste item (electrodes erosion products) of implementing the method of electric-arc treatment of two flat surfaces in the bipolar mode. During the research work, powders from the BT3-1 titanium alloy and the BK-15 hard alloy were obtained and investigated. The proposal was put forward on a possibility of their industrial use, especially for surface spraying. The high-performance methods and appliances were suggested to obtain metal powders using an electric arc in the transverse hydrodynamic flow of the working fluid that burns without a pause. They make it possible to increase dispersion productivity in a fixed-bed layer by an order of magnitude and more as compared with the electro-erosive dispersion, as well as to reduce the number of terminal process waste (i.e. electrodes) by 4 to 6 times.
