Катоды изготавливали методом самораспространяющегося высокотемпературного синтеза. Ассистирующее воздействии газоразрядной плазмы при нанесении покрытия обеспечивалось автономным плазменным источником с накалённым катодом. При этом варьировали потенциал смещения на подложке, время осаждения, состав рабочей газовой среды — аргон и/или смесь аргона с азотом в соотношении 1:1.</p><p>Установлено, что воздействие газоразрядной плазмы на покрытия обеспечивает 2—3-х кратное повышение их твёрдости. Методом энергодисперсионной рентгеновской спектроскопии выявлено наличие в катодах и в покрытиях элементов Mo, S и Ti, C, образующих сульфиды и твёрдые карбиды соответственно. Рентгеноструктурный анализ подтвердил синтез соединений по типу Mo2S3 и TiC и в катодах, и в покрытиях. Наиболее эффективный вариант покрытия, полученного с применением смеси аргона и азота содержит упрочняющую фазу TiN. Триботехнические испытания проводили при трении без смазочного материала. Установлено, что наиболее эффективный вариант покрытия с добавлением азота в плазме, по сравнению с исходным сплавом ВТ5, показал снижение коэффициента трения при нагрузке на контртело 1 Н — в 2 раза, при нагрузке 5 Н — в 3 раза; показатель износа в обоих случаях уменьшился на порядок и более. Таким образом, такой технологический способ обеспечивает формирование градиентно-слоистого покрытия и представляется перспективным для промышленного применения.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work is to identify the most effective conditions and modes for the synthesis of Mo–S–Ti–C coatings on titanium alloy VT5, providing the best tribological characteristics.</p><p>The coatings were applied by vacuum arc evaporation of cathodes on a modernized NNV-6.6-I1 installation. The cathodes were produced using self-propagating high-temperature synthesis. Assistance to the gas discharge plasma during coating application was provided by an autonomous plasma source with a heated cathode. In this case, the bias potential on the substrate, the deposition time, and the composition of the working gas environment — argon and/or a mixture of argon and nitrogen in a ratio of 1:1 — were varied.</p><p>It has been established that the use of assisting action of gas discharge plasma on deposited coatings provides a 2—3 times increase in their hardness. Using energy-dispersive X-ray spectroscopy, the presence of both sulfide-forming elements (Mo, S) and elements capable of forming solid carbides (Ti, C) was revealed in the evaporated cathodes and in the applied coatings. X-ray structural analysis confirmed the synthesis of compounds of the Mo2S3 and TiC type in both cathodes and coatings. In the most effective version of a three-layer coating using, along with argon, additionally nitrogen in gas discharge plasma, the formation of a strengthening phase TiN was also recorded. Tribological tests were carried out under friction conditions without lubricant. It was established that the most effective version of a three-layer coating with the addition of nitrogen in a gas discharge plasma, compared to the initial VT5 alloy, showed a decrease in the friction coefficient under a load on the counterbody of 1 N — by 2 times, under a load of 5 N — by 3 times; the wear rate in both cases decreased by an order of magnitude or more. Thus, the presented technological method ensures the formation of a gradient-layered coating architecture and appears promising for industrial application.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коэффициент трения</kwd><kwd>износ</kwd><kwd>вакуумно-дуговое осаждение</kwd><kwd>газоразрядная плазма</kwd><kwd>многокомпонентное покрытие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>friction coefficient</kwd><kwd>wear</kwd><kwd>vacuum arc deposition</kwd><kwd>gas discharge plasma</kwd><kwd>multicomponent coating</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">Крагельский И.В., Добычин М.Н., Комба-лов В.С.
