Creation of nanostructures on zirconium alloys
(Khmelnytskyi National University, 2020-09-16) Kostyuk, G.I.; Bruiaka, O.O.; Kostyuk, E.G.
It is shown that it is possible to obtain layers of nanostructures of sufficient size up to 0.1 mm by varying the energy of ions, its varieties and charges. To reduce the probability of passing unnecessary reactions can be used zirconium ions and niobium, it’s presents in the zirconium alloy Zr1Hb. Considering the neutrality of materials to water, oxygen and other reagents, you can choose the cheapest ions of heavy metals for the treatment of zirconium alloys.
Principles for creating a new class of cutting tools that ensure the highest possible efficiency of forming and productivity of milling
(Khmelnytskyi National University, 2020-09-16) Kostyuk, Gennadii Igorovich
Value of the ion energy and the ion charge states greatly affect the grain size (with increasing energy of the charge and the grain size increases). Increase the percentage composition of the tungsten carbide results in grain growth, and with the increasing mass ion reduction of the grain size is more significant that it can be used to obtain the required grain size. Designing a cutting tool material with the possibility of for-mation of nanostructures shows that not always increase the proportion of tungsten carbide tool enhances the performance and efficiency, and often the grain size has a decisive influence.
