Abstract. The relevance of the research topic lies in the fact that currently there is a steady tendency to increase the amount of electromagnetic radiation (EMR) occurring in the human environment, which negatively affects the healthy indoor environment and determines the focus of experimental research on protecting humans from factors hazardous to health. This article is devoted to the possibility of creating radioprotective building materials from man-made waste from various deposits of Armenia. Research is aimed at creating a comfortable living area inside buildings through the development of radioprotective sandwich-type materials that reduce the impact of EMR on human health. Work was carried out in the direction of developing samples of radio-absorbing structures and selecting radio-absorbing fillers. The laboratory obtained samples from stone processing waste and waste from the extraction of ore minerals with a density from -1500 to 2000 kg/m3, as well as samples based on expanded perlite and a mineral binder with a density of 250-300 kg/m3 as an internal heat-insulating layer and transferred to the National Scientific Laboratory named after A.I.Alikhanyan (Yerevan Institute of Physics) for proton irradiation. In this work, the samples were subjected to proton irradiation, since it is a component of cosmic radiation, as well as EMR and is capable of penetrating through layers of matter depending on its composition and properties. Some physical and mechanical properties of the resulting materials, such as compressive strength and water absorption, were also studied. In addition, the article contains a review of foreign experience in obtaining radioprotective materials with various types of radiation. At this stage, only proton irradiation has been studied, but work in this direction continues. Subject of study: development of radioprotective materials of the “sandwich” type. Materials and methods: waste of aluminosilicate rocks (tuffs) and waste from the extraction of ore minerals were used. The method of proton irradiation of the obtained materials was used. Results: radioprotective materials have been developed that reduce EMR. Conclusions: The possibility of obtaining radioprotective materials by introducing ore mineral mining waste into the composition of the composite material has been confirmed.

“…In addition to fullfledged reactors, fast neutron research reactors are widely used, with the help of which operating conditions are simulated, structural and fuel materials are tested, new technological solutions are tested and justified, calculation programs and models are verified. In this regard, the issue of creating new materials that will ensure reliable, long-term and safe operation of the reactor throughout the entire life cycle remains relevant [1].…”

The article proposes a method of magnetron vacuum deposition of tungsten carbide coatings on spherical hydride granules. The article also illustrates the features of the microstructure and the uniformity of the resulting coating. The effect of heat treatment on the oxygen content in the near-surface areas of titanium hydride coated with tungsten carbide is investigated. The features of the coating structure were studied using by scanning electron microscopy (SEM) with a built-in energy dispersion spectrometer. Comparative data on thermal oxidation of uncoated spherical granules and granules coated with tungsten carbide are presented.

Increasing the Adherence of Metallic Copper to the Surface of Titanium Hydride

et al. 2021

Studies have been carried out to increase the adhesive interaction between a titanium hydride substrate and a copper coating. An additional layer containing chemically active groups was created on the surface of the spherical titanium hydride by chemisorption modification. This paper discusses the results of scanning electron microscopy (SEM) using energy-dispersive X-ray spectroscopic mapping of coatings obtained on spherical granules of titanium hydride before and after adsorption modification. The mechanism of interaction of the surface of spherical granules of titanium hydride and titanium sulfate salt is proposed. It is shown that the creation of a chemisorbed layer of hydroxotitanyl and the subsequent electrodeposition of metallic copper contribute to the formation of a multilayer shell of a titanium–copper coating on the surface of spherical titanium hydride granules (≡Ti-O-Cu-) with a high adhesive interaction. Results have been given for an experimental study of the thermal stability of the initial spherical granules of titanium hydride and granules coated with a multilayer titanium-copper shell.
