Актуальность данного исследования обусловлена необходимостью разработки эффективных методов восстановления и упрочнения деталей специальной техники, эксплуатируемых в экстремальных условиях. В качестве материала подложки использовалась сталь 12Х18Н10Т. Основное внимание уделено влиянию дистанции напыления (300 мм-400 мм) на физико-механические свойства слоев. С использованием методов XRD, SEM детально изучены микроструктура и фазовые превращения исследуемого покрытия. Установлено, что оптимизация параметров HVOF-процесса позволяет уменьшить уровень декарбидизацию WC до W₂C, сохраняя высокую концентрацию первичных твердых фаз в кобальтовой матрице. Экспериментально доказано, что сформированные покрытия обладают сверхплотной структурой с пористостью менее 1%. Результаты трибологических испытаний и электрохимической коррозии подтвердили высокое качество разработанных покрытий: микротвёрдость возросла в 7 раз, а скорость коррозии снизилась на порядок. Полученные данные расширяют научные представления о механизмах адгезионного и когезионного взаимодействия в композитах WC-Co и предлагают готовое технологическое решение для повышения ресурса узлов военной техники.</p></abstract><trans-abstract xml:lang="en"><p>This work presents the development and experimental validation of a technology for producing WCCo metal-ceramic coatings by high-velocity oxygen-fuel (HVOF) spraying, intended for strengthening and restoring components of military equipment. The coatings were deposited on 12Kh18N10T stainless steel substrates at various spraying distances (300-400 mm). The microstructure, phase composition, surface roughness, microhardness, as well as the tribological and corrosion properties of the obtained coatings were investigated. It was established that the spraying distance has a decisive effect on the formation of the coating structure and its service properties. The optimal spraying regime ensures the formation of a dense lamellar structure with minimal porosity, preservation of the primary WC carbide phase, and limited decarburization to W₂C. It was shown that the microhardness of the coatings is 6-7 times higher than that of the base steel, while the friction coefficient and corrosion rate are significantly reduced compared to the substrate. The obtained results confirm the prospects of WC-Co HVOF coatings for improving the wear resistance, corrosion resistance, and operational reliability of military equipment components operating under high mechanical loads and aggressive environments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>HVOF</kwd><kwd>WC-Co покрытия</kwd><kwd>микроструктура</kwd><kwd>износостойкость</kwd><kwd>коррозионная стойкость</kwd><kwd>упрочнение деталей</kwd><kwd>военная техника</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HVOF</kwd><kwd>WC-Co coatings</kwd><kwd>microstructure</kwd><kwd>wear resistance</kwd><kwd>corrosion resistance</kwd><kwd>surface strengthening</kwd><kwd>military equipment</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование финансировалось Комитетом науки Министерства науки и высшего образования Республики Казахстан (грант № 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">Pawlowski L.
