Karazin popup.description2 Object of research: long planar arc sputtering system; power supply unit for arc sputtering system; hydride-forming metallic alloys based on lanthanum; parameters of the experimental sample of the IFS device; method of determining the composition of metal impurities in a substance. Aim of the work: broadening the technical capabilities of the technological complex of vacuum-plasma coatings deposition for the processing of industrial products; investigation of the influence of gas impurities on the hydride formation properties of alloys based on lanthanum in the process of interaction with hydrogen; production of the test bench for measuring the parameters of the experimental specimen by the IFS method and developing a method for determining the composition of the samples under study. Methods of investigation: secondary ions mass spectrometry, ion-photon spectrometry. The long planar arc sputtering system was created. The power supply unit of the arc sputtering system was upgraded. The study of the composition of the monomolecular surface layers of the hydrogen storage alloy LaNi5 was conducted during interaction with hydrogen in the presence of oxygen as an impurity. Studying the chemical composition of the surface, changing the composition depending on the experimental conditions, as well as determining the role of the alloy components in the hydride formation processes can provide useful information on the initial stages of interaction with gaseous hydrogen, which has gas impurities. The results of the study can be used to improve the metal hydride technologies of compressing, storing and transporting hydrogen in a chemically bonded state. On the basis of a miniature magnetron sputtering system, a test bench was created to measure the parameters of the experimental sample of the IFE source. The use of the magnetron sputtering system as an IFE source greatly increased the efficiency of the formation of the excited particles of the test substance. The use of a film recording of experimental information using a charge-coupled device (CCD-matrix) was proposed, which allowed significantly accelerating the process of data processing and obtaining results regarding the presence of metal impurities in the investigated material. A method for determining the composition of metallic impurities in a substance was developed. The spectra of the glow of excited particles sputtered from the surface of a series of metal samples were obtained and analyzed. Product Description popup.authors І. Афанасьєва І. Оксенюк А.
