Полученные данные свидетельствуют о том, что такая комплексная обработка приводит к созданию многофазной субмикро-нанокристаллической структуры высокоскоростной ячеистой кристаллизации алюминия в поверхностном слое. Объем кристаллизационных ячеек обогащен атомами алюминия, что свидетельствует об образовании твердого раствора на основе алюминия. Нанокристаллические слои, образованные частицами кремния и оксидом иттрия, расположены вдоль границ ячеек. Исследование показывает, что в результате комплексной обработки при плотности энергии электронного пучка 25 Дж/см2 происходит увеличение параметра износа модифицированных образцов в 7,9±0,6 раза и уменьшение коэффициента трения в 1,7±0,15 раза по сравнению с силумином в исходном состоянии. Кроме того, микротвердость модифицированного таким образом поверхностного слоя силумина возрастает по сравнению с исходным состоянием в 1,5±0,12 раза. Повышение плотности энергии электронного пучка до 35 Дж/см2 приводит к увеличению параметра износа силумина в 2,1±0,21 раза, коэффициента трения в 1,13±0,1 раза и снижению микротвердости в 1,3±0,13 раза, при этом все еще превышая заданные характеристики силумина в исходном состоянии. В исследовании предполагается, что многократное увеличение параметра износа при комплексной обработке связано с присутствием в поверхностном слое включений кремния, которые не растворились при модификации, в окружении высокоскоростной ячеистой кристаллизационной структуры. </p></abstract><trans-abstract xml:lang="en"><p>In this study, an integrated treatment approach was employed to modify hypereutectic silumin. This method involved electroexplosive alloying of the surface layer with yttrium oxide powder, followed by irradiation with a pulsed electron beam. The experimental data obtained demonstrate that this integrated treatment results in the formation of a submicron-nanocrystalline structure characterized by high-speed cellular crystallization of aluminum within the surface layer. This structure is composed of crystallization cells enriched with aluminum atoms, indicating the creation of a solid solution based on aluminum. The nanocrystalline layers, formed by silicon particles and yttrium oxide, are positioned at the cell boundaries. The study reveals that, as a consequence of integrated treatment with an electron beam energy density of 25 J/cm2 , the wear parameter of the modified samples increases by 7.9±0.6-fold, and the friction coefficient decreases by 1.7±0.15-fold compared to the initial state. Additionally, the microhardness of the modified silumin surface layer increases by 1.5±0.12-fold compared to the initial state. When the electron beam energy density is elevated to 35 J/cm2, the wear parameter of silumin is enhanced by 2.1±0.21-fold, while the friction coefficient increases by 1.13±0.1-fold. However, the microhardness decreases by 1.3±0.13-fold, while still surpassing the specified characteristics of untreated silumin. This investigation postulates that the substantial increase in the wear parameter during integrated treatment may be attributed to the presence of silicon inclusions in the surface layer that did not dissolve during the modification process. These inclusions are surrounded by the high-speed cellular crystallization structure mentioned earlier. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>силумин</kwd><kwd>электровзрывное легирование</kwd><kwd>импульсный электронный пучок</kwd><kwd>структура</kwd><kwd>параметр износа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silumin</kwd><kwd>electroexplosive alloying</kwd><kwd>pulsed electron beam</kwd><kwd>structure</kwd><kwd>wear parameter</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">Tutunchilar S., Besharati Givi M.K., Haghpanahi M., Asadi P.
