Исследуемые композиты получали методом спекания под давлением, а содержание армирующих включений TiC–Ti составляло 3 об. %, 5 об. %, 7 об. %, 9 об. % и 11 об. %. Показано, что твёрдость исследуемых композитов увеличивается при добавлении металлокерамических включений TiC–Ti до 15 HBW 10/250/30, что более чем на 40 % превосходит твёрдость матричного композита. Выявлено, что композиты, армированные включениями TiC–Ti, обладают большей стойкостью к изнашиванию, по сравнению с матричным композитом без введения упрочняющих включений. Установлено, что наибольшей стойкостью к изнашиванию обладает композит, содержащий 7 об. % включений TiC–Ti, размер которых составляет 100—140 мкм, а увеличение содержания включений до 9 об. % и 11 об. % приводит к увеличению интенсивности изнашивания композита. При введении более 7 об. % композиционных включений TiC–Ti, размер которых составляет 140—200 мкм, также происходит снижение стойкости к изнашиванию. Максимальный коэффициент трения демонстрирует композит, армированный 11 об. % включений TiC–Ti размером 100—140 мкм, который составляет 0,36 ± 0,03, а при увеличении размера включений до 140—200 мкм наибольший коэффициент трения наблюдается при введении 7 об. % TiC–Ti.</p></abstract><trans-abstract xml:lang="en"><p>The paper studies the microstructure, phase composition, mechanical properties and tribological characteristics of copper matrix composites of the Cu–Fe–FeCr–MoS2–C system reinforced with TiC–Ti composite inclusions sized 100—140 and 140—200 μm. The composites under study were obtained by sintering under pressure, and the content of reinforcing TiC–Ti inclusions was 3 vol. %, 5 vol. %, 7 vol. %, 9 vol. % and 11 vol. %. It is shown that the hardness of the composites under study increases with the addition of metalceramic inclusions TiC–Ti increases to 15 HBW 10/250/30, which is more than 40 % higher than the hardness of the matrix composite. It is revealed that composites reinforced with TiC–Ti inclusions have greater wear resistance compared to the matrix composite without the introduction of reinforcing inclusions. It was found that the composite containing 7 vol. % TiC–Ti inclusions 100—140 μm in size has the highest wear resistance, and an increase in the inclusion content to 9 vol. % and 11 vol. % leads to an increase in the wear intensity of the composite. With the introduction of more than 7 vol. % TiC–Ti composite inclusions 140—200 μm in size, a decrease in wear resistance also occurs. The maximum friction coefficient is demon-strated by the composite reinforced with 11 vol. % TiC–Ti inclusions 100–140 μm in size, which is 0.36 ± 0.03, and with an increase in the inclusion size to 140—200 μm, the highest friction coefficient is observed with the introduction of 7 vol. % TiC–Ti.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тормозные системы</kwd><kwd>железнодорожный транспорт</kwd><kwd>металломатричные композиты</kwd><kwd>износ поверхности</kwd><kwd>коэффициент трения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brake systems</kwd><kwd>rail transport</kwd><kwd>metal matrix composites</kwd><kwd>surface wear</kwd><kwd>friction coefficient</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">Xiao J.
