Обычно для получения изделий из этой бронзы используется метод наполнительного литья в металлические формы. В настоящей работе исследовали возможность получения заготовок из бронзы БрО10С2Н3 методами горячей экструзии и непрерывного литья вверх. Были установлены температура и скорость горячей экструзии, а также скорость вытягивания при непрерывном литье, позволяющие избежать возникновения дефектов. Показано, что горячая экструзия очень сильно измельчает зерно до 1,7 мкм, а при литье вверх, наоборот, размер зерна увеличивается в сравнении с методом наполнительного литья. Что же касается микроструктуры, то при горячей экструзии и непрерывном литье вверх происходит измельчение кристаллов интерметаллидной фазы Y-Cu3Sn. При этом в структуре бронзы после горячей экструзии можно наблюдать крупные скопления частиц (Pb), что, по всей видимости, приводит к снижению коэффициента трения. Максимальная твердость и прочностные свойства при растяжении характерны для прутков, полученных методом горячей экструзии при 600 °С, а наибольшее относительное удлинение было обнаружено в прутках, полученных методом непрерывного литья вверх. Трибологические исследования, проведенные по схеме «вал — частичный вкладыш» в среде керосина со стальным контртелом, показали, что применение горячей экструзии для получения прутков приводит к 10-кратному увеличению износостойкости и 3-кратному снижению коэффициента трения в сравнении со слитками, изготовленными наполнительным литьем. При этом для прутков, полученных методом непрерывного литья вверх, наоборот, наблюдается уменьшение износостойкости. В связи с вышесказанным можно рекомендовать метод горячей экструзии для получения заготовок из бронзы БрО10С2Н3 наравне с литьем.</p></abstract><trans-abstract xml:lang="en"><p>In mechanical engineering, the antifriction tin bronzes, and C92900 bronze for instance are used for parts subjected to wear. The permanent mold casting into steel molds are commonly used to produce parts from C92900 bronze. This work investigates the possibility of C92900 bronze rods production by hot extrusion and upcasting methods. It has been discovered the hot extrusion temperature and ram speed, as well as the casting speed for upcasting that promote no defects in rods. It has been shown that hot extrusion leads to severe grain refinement up to 1.7 gm, and when casting upwards, on the contrary, an increase in the grain size occurs in comparison with the permanent mold casting. After hot extrusion and upcasting, the crystals of the Y-Cu3Sn intermetallic phase are refined in the bronze microstructure. At the same time, large agglomerations of (Pb) particles can be observed in the extruded bronze microstructure, which leads to a decrease in the coefficient of friction. The maximum hardness and tensile strength were obtained for rods produced by hot extrusion at 600 °C, and the highest elongation in rods obtained by the upcasting method. Tribological studies were carried out according to the «shaft — partial insert» scheme in a kerosene medium with a steel counter body showed that hot extrusion leads to a tenfold increase in wear resistance and a threefold decrease in the friction coefficient in comparison with rods obtained by permanent mold casting. At the same time, for the rods obtained by the upcast method, on the contrary, a decrease in wear resistance is observed. In connection with the mentioned results, it is possible to recommend the hot extrusion method for producing C92900 bronze rods in addition with casting technique.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антифрикционная бронза</kwd><kwd>БрО10С2Н3</kwd><kwd>горячая экструзия</kwd><kwd>литье вверх</kwd><kwd>интенсивность износа</kwd><kwd>механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antifriction bronze</kwd><kwd>C92900</kwd><kwd>hot extrusion</kwd><kwd>upcasting</kwd><kwd>wear rate</kwd><kwd>mechanical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена при финансовой поддержке Министерства науки и высшего образования РФ по материалам работ, выполняемых в НИТУ «МИСиС» в рамках комплексного проекта по созданию высокотехнологичного производства: «Разработка технологии производства уникальных литых деталей из сплавов цветных металлов для летательных аппаратов на базе цифровых технологий и применения перспективных импортозамещающих материалов с целью повышения конкурентоспособности отечественного авиастроения» (Соглашение от 22 ноября 2019 г. № 075-11-2019-045, заключенное в целях реализации комплексных проектов по созданию высокотехнологичных производств в рамках подпрограммы «Инфраструктура научной, научно-технической и инновационной деятельности» государственной программы РФ «Научно-технологическое развитие Российской Федерации», утвержденных постановлением Правительства РФ № 218 от 9 апреля 2010 г.).</funding-statement><funding-statement xml:lang="en">This research received financial support from the Ministry of Science and Higher Education in the Russian Federation (Agreement № 075-11-2019-045 from 22 November 2019) under the program «Scientific and technological development of the Russian Federation» according to governmental decree № 218 dated 9 April 2010.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Груздева И.А., Сулицын А.В., Мысик Р.К., Сокунов Б.А.
