Покрытия формировались на поверхности шлифованной высокоуглеродистой стали методом электроосаждения из водного электролита на основе сульфата никеля (NiSO4) и молибдата натрия (Na2MoO4) с дисперсным GrO. Покрытия получали при плотности тока 2,5 А/дм² и концентрациях GrO от 0,05 до 0,2 г/л. Триботехнические испытания показали, что введение GrO в концентрации 0,1 г/л способствует формированию покрытия с равномерной структурой, обеспечивающей минимальный коэффициент трения (0,38—0,45) и ширину дорожки трения (25—110 мкм) при нагрузке 0,25—1,0 Н. Выявлена зависимость триботехнических характеристик от концентрации частиц графена в рабочем растворе: при 0,1 г/л достигается равномерное распределение частиц GrO, что приводит к снижению коэффициента трения на 30–40 % и уменьшению ширины дорожки трения на 40—55 % по сравнению с базовым Ni–Mo покрытием. При увеличении концентрации частиц выше 0,1 г/л наблюдается рост шероховатости покрытий, что очевидно вызвано агломерацией и избыточным включением частиц наполнителя в структуру покрытия, что в совокупности приводит к формированию более грубой и неоднородной поверхности и ухудшающий его триботехнические свойства. Полученные результаты подтверждают перспективность использования GrO в составе электролитических Ni–Mo покрытий для снижения трения и увеличения износостойкости.</p></abstract><trans-abstract xml:lang="en"><p>The effect of co-deposited graphene oxide (GrO) modified with COOH groups on the tribological characteristics of electrolytic nickel-molybdenum coatings has been studied. The coatings were formed on the surface of polished high-carbon steel by electrodeposition from an aqueous electrolyte based on nickel sulfate (NiSO4) and sodium molybdate (Na2MoO4) with dispersed graphene oxide. The coatings were obtained at current densities 2,5 A/dm² and GrO concentrations from 0.05 to 0.2 g/L. Tribotechnical tests have shown that introduction of GrO at a concentration of 0.1 g/L promotes the formation of a coating with a uniform structure, ensuring a minimum friction coefficient (0.38—0.45) and a wear track width (25—110 µm) under a load of 0.25—1.0 N. A dependency of tribological characteristics on the concentration of graphene particles in the working solution was revealed: at 0.1 g/L, a uniform distribution of GrO particles is achieved, leading to a 30—40 % reduction in the friction coefficient and a 40—55 % decrease in wear track width compared to the base Ni–Mo coating. When the particle concentration exceeds 0.1 g/L, an increase in coating roughness is observed, likely caused by agglomeration and excessive inclusion of filler particles in the coating structure, which results in the formation of a rougher and more heterogeneous surface, thereby degrading the tribological properties of the coating. The obtained results confirm the promising use of GrO in the composition of electrolytic Ni-Mo coatings to reduce friction and increase wear resistance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>никель-молибденовые покрытия</kwd><kwd>электроосаждение</kwd><kwd>нанонаполнители</kwd><kwd>оксид графена</kwd><kwd>трение</kwd><kwd>износостойкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel-molybdenum coatings</kwd><kwd>electrodeposition</kwd><kwd>nanofillers</kwd><kwd>graphene oxide</kwd><kwd>friction</kwd><kwd>wear resistance</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">Сайфуллин Р.С.
