Электрофрикционная обработка основана на совместном оплавлении поверхностей электрода из чугуна и лезвия почвообрабатывающего инструмента, путем ввода энергии низковольтных электрических дуг и охлаждения водой. Результаты исследования показали, что при электрофрикционной обработке скорость перемещения образца относительно к вращающему электроду влияет на толщину обрабатываемого слоя. Высокоскоростная обработка формирует сравнительно невысокую глубину упрочнения и большие размеры переходной области (около 1 мм) с плавным снижением микротвердости. При обработке на низкой скорости в наплавленном слое возможно образование микротрещин. Электрофрикционная обработка стали 65Г при токе 300 А увеличивает микротвердость поверхностного слоя в три раза, а для стали 40Х в четыре раза, по сравнению с исходными значениями 297 HV0.1и 238 HV0.1 соответственно. Интенсивность износа сталей 40Х и 65Г, упрочненных электрофрикционным способом при знамениях тока 100 А, 200 А и 300 А, в 2-3 раза меньше, чем неупрочненного сталей, что свидетельствует о значительной эффективности данного метода упрочнения при абразивном изнашивании.</p></abstract><trans-abstract xml:lang="en"><p>This work examines the influence of parameters of electrofrictional processing (current, processing speed) on the mechanical-tribological properties of construction steels 65G and 40Kh. Electrofrictional processing is based on the simultaneous melting of the surfaces of a cast iron electrode and a soil-processing tool blade, achieved by introducing energy through low-voltage electric arcs and cooling with water. The results of the study showed that during electrofrictional processing, the speed of sample movement relative to the rotating electrode affects the thickness of the processed layer.High-speed processing forms a relatively shallow hardening depth and large dimensions of the transition zone (about 1 mm) with a smooth decrease in microhardness. Low-speed processing can result in the formation of microcracks in the deposited layer. Electrofrictional processing of 65G steel with a current of 300 A increases the microhardness of the surface layer three times, while for 40Kh steel, it increases four times, compared to the initial values of 297 HV0.1 and 238 HV0.1, respectively. The wear intensity of 40Kh and 65G steels, hardened by electrofrictional processing with current values of 100 A, 200 A, and 300 A, is 2-3 times lower than that of non-hardened steels, indicating the significant effectiveness of this hardening method in abrasive wear.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрофрикционная обработка</kwd><kwd>средне- и высокоулеродистые стали</kwd><kwd>трибологическое испытание</kwd><kwd>микротвердость</kwd><kwd>абразивный износ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrofrictional treatment</kwd><kwd>medium- and high-carbon steels</kwd><kwd>tribological testing</kwd><kwd>microhardness</kwd><kwd>abrasive wear</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данное исследование финансировалось Комитетом науки Министерства науки и высшего образования Республики Казахстан (грант №BR24992876).</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">Abrasive wear behaviour of 27MnB5 steel used in agricultural tines / Á.
