Один из образцов исследуемого материала был подвергнут обработке лазерным излучением, с локальным лазерным разогревом поверхностного слоя до 2800—3000 °C. Другой образец композита был термически обработан при температуре T &gt; 2000 °С. Были проведены триботехнические испытания и получены значения коэффициентов трения и изнашивания в паре со стальным и керамическим контртелами. С целью определения особенностей механизмов трения и изнашивания модифицированных материалов, поверхность композитов после трения была исследована методом сканирующей электронной микроскопии с рентгеноспектральным анализом. Установлено, что лазерная обработка значительно улучшает антифрикционные свойства углеродного композита в паре со стальным контртелом (уменьшение коэффициента трения в два раза, уменьшение износа в три раза). Выявлено, что такая обработка значительно меняет характер плёнки вторичных структур (ВС), формирующейся на поверхности трения композитов в паре со сталью. В составе плёнки не обнаруживаются элементы материала контртела, что свидетельствует о его минимальном износе в процессе трения. Сама плёнка ВС становится толще и плотнее, полностью покрывая поверхность композита. Это позволяет ей в большей степени проявлять твёрдосмазочные и противоизносные свойства, улучшая триботехнические характеристики композита.</p></abstract><trans-abstract xml:lang="en"><p>The study of structure and tribotechnical characteristics of composite material based on carbon PAN fabric and matrix obtained by vapor deposition method has been carried out. One of the samples of the investigated material was subjected to laser treatment, with local laser heating of the surface layer to 2800—3000 °C. The other composite sample was heat treated at a temperature T &gt; 2000 °C. Tribotechnical tests were carried out and values of friction and wear coefficients were obtained in the pair with steel and ceramic counterbodies. In order to determine the peculiarities of friction and wear mechanisms of modified materials, the surface of composites after friction was investigated by scanning electron microscopy with X-ray spectral analysis. It was found that laser treatment significantly improves antifriction properties of carbon composite in pair with steel counterbody (friction coefficient reduction by two times, wear reduction by three times). It is revealed that such treatment significantly changes the nature of the film of secondary structures (SS) formed on the friction surface of composites paired with steel. In the composition of the film elements of the counterbody material are not found, which indicates its minimal wear in the process of friction. The BC film itself becomes thicker and denser, completely covering the composite surface. This allows it to a greater extent to show solid-lubricating and anti-wear properties, improving tribotechnical characteristics of the composite.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>углерод-углеродный тканевый композит</kwd><kwd>лазерная термообработка</kwd><kwd>коэффициент трения</kwd><kwd>износостойкость</kwd><kwd>трибология композитов</kwd><kwd>структура композитов</kwd><kwd>сканирующая электронная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbon-carbon fabric composite</kwd><kwd>laser heat treatment</kwd><kwd>friction coefficient</kwd><kwd>wear resistance</kwd><kwd>composite tribology</kwd><kwd>composite structure</kwd><kwd>scanning electron microscopy</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">Sarower K., Chowdhury A.S., Sazzad H.A., Imtiaz A.C., and Faiz A.
