Установлена независимость фазового состава композиционных материалов (КМ) от метода спекания и температуры в интервале 900–1200 °С. Особенностями формирования структуры КМ при спекании являются деинтеркалирование кремния из карбосилицида титана, образование твердого раствора углерода на базе силицида титана Ti5Si3(С), небольших количеств карбида титана, карбида кремния и силицида TiSi2. Увеличение концентрации Ti3SiС2 в КМ приводит к некоторому снижению электропроводящих свойств, но значительному повышению твердости, прочности и электроэрозионной износостойкости электродов из КМ для электроэрозионной прошивки.</p></abstract><trans-abstract xml:lang="en"><p>The study covers the formation of structure and properties during infiltration, pressureless and spark plasma sintering in Cu – (12,5÷37,5 vol.%) Ti3SiC2 powder materials using electron microscopy, X-ray phase and energy dispersive analysis methods. The paper determines the independence of composite material (CM) phase composition from the sintering method and the temperature within 900–1200 °C. Special aspects of CM structure formation during sintering include deintercalation of silicon from titanium carbosilicide, formation of a solid carbon solution based on titanium silicide Ti5Si3(С), small amounts of titanium carbide, silicon carbide and silicide TiSi2. The increased concentration of Ti3SiC2 in CM leads to a certain decrease in electrical conductivity, but also to a significant increase in hardness, strength and wear resistance of the electroerosion electrode composites for EDM.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>структура</kwd><kwd>композиционный материал</kwd><kwd>медь</kwd><kwd>карбосилицид титана</kwd><kwd>спекание</kwd><kwd>SPS</kwd><kwd>инфильтрация</kwd><kwd>физико-механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>structure</kwd><kwd>composite material</kwd><kwd>copper</kwd><kwd>Ti3SiC2</kwd><kwd>sintering</kwd><kwd>SPS</kwd><kwd>infiltration</kwd><kwd>physical and mechanical properties</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">Елисеев Ю.С., Саушкин Б.П.
