Методами сканирующей электронной микроскопии и рентгеноспектрального микроанализа изучено влияние многокомпонентного легирования на микроструктуру околоэвтектического силумина. Многокомпонентное легирование эвтектического сплава Al–Si магнием, марганцем, железом, никелем и медью приводит к уменьшению уменьшение размеров первичных дендритов α-Al до 3—4 мкм. Триботехнические испытания проведенные в условиях сухого трения при возвратно поступательном движении индентора, показали, что легированние металлами быстрозатвердевших сплавов эвтектического силумина обеспечивает снижение коэффициента трения на 25 %. Анализ поверхностного состояния образовашегося трека показал, что в результате деформационного нагрева протекает окисление фазы α-Al, разрушение окисной плёнки, представляющей собой третье тело, и вынос её за пределы трека. Также было обнаружено раздробление пластин кремния в зоне трека в наноразмерные частицы. Воздействие индентора также приводит однородному распределению равноосных частиц интерметаллических соединении при сохранении их фазового состава.</p></abstract><trans-abstract xml:lang="en"><p>The results of a study of the tribological properties and microstructure of rapidlysolidified Al — 12.2 wt. % Si — 0.2 wt. % Fe (AK12vp) and Al — 12.5 wt. % Si — 0.8 wt. % Mg — 0.4 wt. % Mn — 0.7 wt. % Fe — 0.9 wt. % Ni — 1.7 wt. %, Cu (Al–Si–M) alloys are presented. The effect of multicomponent alloying on the microstructure of near-eutectic silumin was studied using scanning electron microscopy and X-ray spectrometry. Multicomponent alloying of the Al—Si eutectic alloy with magnesium, manganese, iron, nickel and copper leads to a reduction in the size of the primary α-Al dendrites to 3—4 μm. Tribological tests carried out under conditions of dry friction with reciprocating motion of the indenter showed that alloying by metals of rapidly solidified eutectic silumin leads to a reduction in the coefficient of friction by 25 %. An analysis of the surface state of the track showed that, as a result of deformation heating, the oxidation of the α-Al phase occurs, the destruction of the oxide film, which represents the third body, and its removal beyond the track. The fragmentation of silicon plates in the track area into nano-sized particles was also obtained. The impact of the indenter also leads to a uniform distribution of equiaxed particles of intermetallic com-pounds while maintaining their phase composition.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоскоростное затвердевание</kwd><kwd>силумины</kwd><kwd>микроструктура</kwd><kwd>коэффициент трения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rapid solidification</kwd><kwd>silumins</kwd><kwd>microstructure</kwd><kwd>coefficient of friction</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">Peeru Naika M. and Balaram Padal K.T.
