Образцы подвергались различным методам обработки, включая электролитически-плазменную закалку, азотирование, цементацию, азотноуглеродное насыщение и процессы закалки. Для всестороннего описания структуры, фазового состава и механических свойств образцов было использовано несколько методов анализа: сканирующая электронная микроскопия, спектроскопия энергодисперсии, рентгеноструктурный анализ и микротвердостные измерения. Трибологические свойства материалов оценивали с помощью трибометра TRB3, а испытания на абразивный износ проводились в соответствии со стандартом ГОСТ 23.208-79. Результаты показали, что при электролитически-плазменной обработке образуются диффузионные слои толщиной 15-25 мкм. Этот процесс сопровождается образованием карбидной, нитридной и карбонитридной фаз (Fe₄C, Fe₇C₃, Fe₄N, Fe₂N и Fe₃(CN)). Указанная обработка значительно увеличивает твердость поверхности (до 810 HV) и улучшает износостойкость. Результаты исследования показали, что электролитически-плазменное азотирование обеспечивает оптимальный баланс твердости и вязкости, в результате чего снижается коэффициент трения и повышается износостойкость абразива. Разработка этой технологии позволит продлить срок службы деталей землеройного и горнодобывающего оборудования, снизить затраты на техническое обслуживание и время простоя оборудования.</p></abstract><trans-abstract xml:lang="en"><p>This study examines how electrolytic plasma treatment can improve the wear resistance of 30CrMnSi bucket teeth used in loaders operating under severe abrasive conditions. Samples were subjected to various processing methods, including electrolytic plasma hardening, nitriding, carburizing, nitrocarburizing hardening, and quenching. Multiple analytical techniques, including scanning electron microscopy energy dispersive spectroscopy, X-ray diffraction, and microhardness testing, were used to comprehensively characterize the structure, phases, and mechanical properties of the samples. The tribological properties of the materials were evaluated using a TRB3 tribometer, and abrasive wear testing was conducted according to GOST 23.208–79. The results show that electrolytic plasma treatment results in the formation of diffusion layers with a thickness of 15 to 25 μm. This process is accompanied by the formation of carbide, nitride, and carbonitride phases (Fe₄C, Fe₇C₃, Fe₄N, Fe₂N, and Fe₃(CN)). This process significantly increases surface hardness (up to 810 HV) and improves wear resistance. The study also showed that electrolytic plasma nitriding provides an optimal balance between hardness and toughness, resulting in low friction and increased resistance to abrasive wear. The development of this technology can extend the service life of earthmoving and mining equipment components, reducing maintenance costs and downtime.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ковшовые зубья</kwd><kwd>химико-термическая обработка</kwd><kwd>электроразрядная поверхностная химико-термическая обработка</kwd><kwd>абразивный износ</kwd><kwd>микротвердость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bucket teeth</kwd><kwd>chemical-thermal treatment</kwd><kwd>electric discharge surface chemi-cal-thermal treatment</kwd><kwd>abrasive wear</kwd><kwd>microhardness</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research has been funded by the Committee of Science Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant № BR24992879).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Florea V.A.
