На твердый сплав ВК10КС способом электроискровой обработки наносится сплав ВК6­ОМ толщиной 20 мкм. При этом получается поверхностный упрочненный слой, состоящий из W2C. Твердость получаемого слоя составляет 22 000 МПа, коэффициент трения 0,23 (по сравнению с коэффициентом трения исходного твердого сплава 0,41), сохраняется прочная, но недостаточно износостойкая основа. В работе способом однокомпонентного электровзрывного легирования титаном был получен поверхностный слой на твердом сплаве ВК10КС толщиной 40 мкм, фазовый состав TiC, W2C. Нанотвердость данного слоя 25 000 МПа, коэффициент трения 0,14. На твердом сплаве ВК10КС способом многокомпонентного электровзрывного легирования титаном совмест­ но с бором получен поверхностный слой толщиной 3 – 4 мкм фазовым составом TiB2 , TiC, W2C. Нанотвердость упрочненного слоя 27 500 МПа, коэффициент трения 0,10. Применяя методику раздельных катодов, на поверхность твердого сплава ВК10КС было нанесено ионно­плазменное TiN + ZrN покрытие (50 % Ti + 50 % Zr) толщиной 20 мкм. В качестве реакционного газа использовался азот. Нано­твердость упрочненного таким способом поверхностного слоя составляет 38 500 МПа, коэффициент трения 0,07. Ионно­плазменное TiN + ZrN покрытие обладает хорошей адгезией с основой. Использование предлагаемых способов поверхностного упрочнения твердого сплава ВК10КС дает возможность выбора одного из методов упрочнения исходя из условий эксплуатации твердосплавного инструмента, продлить его эксплуатационный срок; сэкономить дефицитные материалы (вольфрам и кобальт).</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of surface hardening of tungsten­carbide hard alloys carried out using concentrated energy flows. The VK6­OM alloy with a thickness of 20 μm is applied to the hard alloy VK10KS by the method of electric spark treatment. In this case, a surface hardened layer consisting of W2C is obtained. The hardness of the resulting layer is 22,000 MPa and the friction coefficient is 0.23 (compared to the friction coefficient of the original hard alloy of 0.41); strong but insufficiently wear­resistant base is preserved. In the work, a surface layer on a hard alloy VK10KS with a thickness of 40 μm and phase composition of TiC and W2C was obtained by the method of single­component electro­explosive alloying with titanium. The nanohardness of this layer is 25,000 MPa and the friction coefficient is 0.14. A surface layer with thickness of 3 – 4 μm and phase composition of TiB2 , TiC, W2C was obtained on the hard alloy VK10KS by the method of multicomponent electro­explosive alloying with titanium and boron. The nanohardness of the hardened layer is 27,500 MPa and the friction coefficient is 0.10. Applying the technique of separate cathodes, an ion­plasma TiN + ZrN coating (50 % Ti + 50 % Zr) with a thickness of 20 μm was applied to the surface of the VK10KS hard alloy. Nitrogen was used as the reaction gas. The nanohardness of the surface layer hardened in this way is 38,500 MPa and the friction coefficient of is 0.07. Ion­plasma TiN + ZrN coating has good adhesion to the substrate. The use of the proposed methods of surface hardening of VK10KS hard alloy makes it possible to choose one of the hardening methods, based on operating conditions of the carbide tool, to extend its operational life, as well as to save scarce materials (tungsten and cobalt).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностная обработка</kwd><kwd>сплав</kwd><kwd>микроструктура</kwd><kwd>нанотвердость</kwd><kwd>износ</kwd><kwd>коэффициент трения</kwd><kwd>трек износа</kwd><kwd>фазы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surface treatment</kwd><kwd>alloy</kwd><kwd>microstructure</kwd><kwd>nanohardness</kwd><kwd>wear</kwd><kwd>friction coefficient</kwd><kwd>wear track</kwd><kwd>phases</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Табаков В.П.
