Настоящее исследование посвящено изучению влияния плазменного жидкофазного легирования на физико-механические свойства приповерхностного слоя вольфрама и его сплавов. Экспериментальные образцы вольфрама с покрытиями из меди и циркония подвергались воздействию компрессионными плазменными потоками (КПП). Элементный состав образцов определялся методом энергодисперсионной рентгеновской спектроскопии (ЭДС), а деформация кристаллической решетки и остаточные напряжения оценивались методом рентгеновской дифракции. Результаты ЭДС показали, что плазменное воздействие приводит к формированию однородного сплава вольфрама и циркония в приповерхностном слое. Обработка вольфрама КПП вызывает увеличение уровня деформации решетки. В приповерхностном слое W-КПП обнаружены растягивающие напряжения величиной до 6 ГПа, тогда как для системы легированной медью W-Cu наблюдаются сжимающие напряжения, стремящиеся к нулю. Для системы W-Zr максимальные растягивающие напряжения достигают около 5–6 ГПа. Установлено, что введение меди в вольфрам существенно снижает уровень остаточных внутренних напряжений по сравнению с легированием цирконием. Полученные результаты могут способствовать разработке новых сплавов вольфрама с улучшенными эксплуатационными характеристиками для применения в термоядерной энергетике и других областях.

This study is devoted to studying the influence of plasma liquid-phase alloying on the physical and mechanical properties of the surface layer of tungsten and its alloys. Experimental samples of tungsten with copper and zirconium coatings were exposed to compression plasma flows (CPF). The elemental composition of the samples was determined by energydispersive X-ray spectroscopy (EDS), and lattice deformation and residual stresses were assessed using X-ray diffraction. The results of EDS showed that plasma exposure leads to the formation of a homogeneous alloy of tungsten and zirconium in a near-surface layer. Treatment of tungsten by CPF causes an increase in the level of lattice deformation. In the surface layer of W-CPF tensile stresses with a value up to 6 GPa were observed, while for the system alloyed with copper W-Cu, compressive stresses tending to zero were observed. For the W-Zr system, the maximum tensile stresses reached around 5–6 GPa. It has been established that the introduction of copper into tungsten significantly reduces the level of residual internal stresses compared to alloying with zirconium. The results obtained may contribute to the development of new tungsten alloys with improved performance characteristics for use in fusion energy and other fields.
