Экспериментально установлено, что после ЭПО микротвёрдость увеличивается в 2–2,5 раза, а коэффициент износа уменьшается более чем на три порядка. Для оценки поведения зубьев борон в условиях эксплуатации выполнено численное моделирование в среде COMSOL Multiphysics. Применённая модель, основанная на законе Арчарда, позволила рассчитать контактные напряжения при взаимодействии зуба бороны с тяжёлым суглинком, а также спрогнозировать толщину и объём износа при различных режимах нагрузки. Вычисленные значения контактного напряжения (4,58·107 Н/м2 при движении по горизонтали и 5,31·108 Н/м2 при погружении в почву) использовались для расчётов износа. Расчёты показали, что упрочнённые зубья демонстрируют значительно меньший объём износа (≈11,7–11,8 мм3/км), тогда как для исходной стали 45 без ЭПУ этот показатель составляет ≈79 см3/км. Результаты исследования подтверждают, что электролитно-плазменное упрочнение эффективно снижает износ зубьев борон, увеличивает их эксплуатационный ресурс и позволяет прогнозировать срок службы без проведения натурных испытаний. Представленный метод упрочнения является перспективным для применения в сельскохозяйственной технике, так как он не только повышает долговечность рабочих органов, но и может способствовать снижению эксплуатационных затрат.</p></abstract><trans-abstract xml:lang="en"><p>The paper investigates the impact of electrolytic plasma treatment (EPT) on the wear resistance of harrow teeth fabricated from grade 45 steel. Experimental results demonstrate that EPT leads to a 2–2.5 fold increase in microhardness and a more than three-order-of-magnitude reduction in the wear coefficient. Numerical modeling using COMSOL Multiphysics was employed to assess the behavior of harrow teeth under operational conditions. The model, based on Archard's law, enabled the calculation of contact stresses during the interaction of a harrow tooth with dense soil, as well as the prediction of wear thickness and volume under various load conditions. The computed contact stress values were utilized to estimate wear (4.58·107 N/m2 when moving horizontally and 5.31·108 N/m2 when immersed in soil). The calculations reveal that hardened teeth exhibit significantly lower wear volumes (≈11.7–11.8 mm3/km), while for the original steel 45 without EPT, this figure is approximately 79 cm3/km. The study findings confirm that electrolytic plasma hardening effectively reduces harrow tooth wear, extends their service life, and allows service life prediction without full-scale testing. This hardening method holds promise for agricultural machinery, as it enhances the durability of working components and can help lower operating costs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электролитно-плазменная закалка (ЭПЗ)</kwd><kwd>микротвердость</kwd><kwd>износ</kwd><kwd>сталь 45</kwd><kwd>контактные напряжения</kwd><kwd>зубья борон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrolytic plasma hardening (EPH)</kwd><kwd>microhardness</kwd><kwd>wear</kwd><kwd>grade 45 steel</kwd><kwd>contact pressure</kwd><kwd>harrow teeth</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research was supported by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan under the grant project No. BR24992870.</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">Акимбекова Г.
