    Improved hard alloys for efficient milling
    (2015) Zhigalov, A. N.; Maslov, A. R.; Shaturov, G. F.
    Milling efficiency is improved by aerodynamic modification of the surface structure of hard-alloy tools. A physical interpretation of this method is outlined. Test results for the proposed tool and a standard tool are compared.

    Investigation of the wear of a tool with carbide tips, hardened by the method of aerodynamic impact
    (Lviv Polytechnic National University, 2017) Zhygalov, A. N.; Stupnytskyy, V. V.; Жигалов, А. Н.
    Theoretical calculations and experimental studies of the influence of wear on the cutting process and the precision parameters of machining by hard alloys during milling are described in the article. The method of aerodynamic hardening is designed to increase the durability of tools, which are heterogeneous compositions of tungsten carbides, titanium and tantalum with cobalt ligature operating under severe process conditions with varying impact loads. The effect of hardening by the ADH method is achieved due to the influence of sound waves on the structure of hard alloys. The results of imitation studies of the wear process in the DEFORM system are described.

    A method of increasing hard-alloy wear resistance via aerodynamic impact
    (2014) Maslov, A. R.; Jigalov, A. N.
    The paper presents the effect of an increase in wear resistance after several operating cycles of hard-alloy plates is investigated and the results of investigations. The plate is heated to one-third of the melting temperature and subjected to air fluctuations with frequencies of 160–800 Hz. A hypothesis on how aerodynamic impacts occur on hard alloy surfaces is presented. An experimental way to strengthen the surface layer of metal cutting plates is described. It is revealed that under industrial condition the mean time between failures for the plates processed by mentioned procedure is 1.8–2.2 times higher than for the standard delivery plates.

    Самоорганизация структуры системы ТiС-Со при аэродинамическом упрочнении
    (МГТУ «СТАНКИН», 2018) Жигалов, А. Н.; Маслов, А. Р.; Zhigalov, A. N.; Maslov, A. R.
    Рассмотрены основные превращения субструктур в твердых сплавах, подвергнутых воздействию волнами звуковой частоты. Изложен принцип самоорганизации в кристаллических и дислокационных структурах твердых сплавов. The basic transformation of sub-strukture in solid alloys subjected effects waves of sound frequency. Lays down the principle of self-organization in crystalline and dislocation structures of hard alloys.
