В данной статье исследована технология получения сплава на основе LaNi₅ методом искрового плазменного спекания (ИПС) для хранения водорода. Предварительная механическая активация и механический синтез проводились с использованием металлических порошков лантана (La) и никеля (Ni) в массовых соотношениях 20:1 и 30:1. Подготовленные порошковые смеси помещались в графитовую матрицу диаметром 20 мм, предварительно подпрессовывались и спекались на установке искрового плазменного спекания ISKRA при температуре 1250°C и постоянном давлении в среде вакуума.Для фазового анализа синтезированных образцов использовался метод рентгеновской дифрактометрии, в результате чего были определены фазовые превращения и кристаллические особенности структуры сплава. В результате было установлено, что наблюдается образование фазы LaNi₅. Помимо основной фазы, обнаружен также оксид La₂O₃, что свидетельствует о частичном окислении материала. Кроме того, морфология и микроструктура материала были исследованы с помощью сканирующего электронного микроскопа, что позволило охарактеризовать поверхностную структуру и распределение размеров частиц полученных образцов. Результаты исследования подтвердили эффективность метода механического синтеза и искрового плазменного спекания для получения материала на основе LaNi₅ для хранения водорода и позволили определить влияние параметров синтеза на фазовый состав и микроструктурные характеристики полученного материала.

In this paper, we study the technology of producing a LaNi₅-based alloy by spark plasma sintering (SPS) for hydrogen storage. Preliminary mechanical activation and mechanical synthesis were carried out using lanthanum (La) and nickel (Ni) metal powders in mass ratios of 20:1 and 30:1. The prepared powder mixtures were placed in a graphite matrix with a diameter of 20 mm, pre-pressed and sintered on an ISKRA spark plasma sintering unit at a temperature of 1250 °C and constant pressure in a vacuum environment.

X-ray diffractometry was used for phase analysis of the synthesized samples, as a result of which phase transformations and crystalline features of the alloy structure were determined. As a result, it was found that the LaNi₅ phase is formed. In addition to the main phase, La₂O₃ oxide was also detected, which indicates partial oxidation of the material. In addition, the morphology and microstructure of the material were studied using a scanning electron microscope, which allowed us to characterize the surface structure and particle size distribution of the obtained samples. The results of the study confirmed the effectiveness of the mechanical synthesis and spark plasma sintering method for obtaining a LaNi₅-based material for hydrogen storage and made it possible to determine the effect of synthesis parameters on the phase composition and microstructural characteristics of the obtained material.
