В этой статье рассмотрены влияния диффузионного электролитно-плазменного борирования на структуру и трибологические характеристики стали 40Х. Методами рентгеновской дифракции и сканирующей микроскопии были исследованы структурно-фазовый состав, а механические и трибологичекие свойства стали были оценены твердомером и трибометром. Были сравнены характеристики стали 40Х в исходном состоянии и после диффузионной электролитно-плазменной обработки с последующим удалением оксидов электрохимическим полированием. После диффузионной электролитно-плазменной обработки на рентгеновских дифрактограммах были обнаружены боридные фазы FeB и Fe₂B, которые подтверждают процесс диффузии. Так же было определено повышение микротвердости в 5 раз и снижение интенсивности изнашивания до 3 раз в зависимости от исходного состояния. Установлено, что морфология структуры после борирования имеет зональность, состоящяя из 3-зон: борированный слой, дифузионная зона и зона термического влияния. Данные исследования свидетельствует о перспективности использования диффузионной электролитно-плазменной обработки в машиностроении и обработке деталей горно-рудной промышленности.

This article studies the effects of diffusion electrolytic plasma boriding on the structure and tribological characteristics of 40Kh steel. X-ray diffraction and scanning microscopy were used to investigate the structural and phase composition, while the mechanical and tribological properties of the steel were measured using a hardness tester and tribometer. The characteristics of 40Kh steel in its initial state and after diffusion electrolytic plasma treatment followed by oxide removal by electrochemical polishing were compared. After diffusion electrolytic-plasma treatment, FeB and Fe₂B boride phases were detected on X-ray diffractograms, proving the diffusion process. A 5 times increase in microhardness and a 3 times decrease in wear intensity were also determined, depending on the initial state. It was established that the morphology of the structure after boriding has a zonality consisting of three zones: the borided layer, the diffusion zone, and the heat-affected zone. The research data indicates the potential of using diffusion electrolytic-plasma treatment in mechanical engineering and the processing of parts for the mining industry.
