Major achievements:

The kinetics of phase redistribution in the MoSi₂–W system at 1500 – 1800°С was studied. The kinetic parameters for the growth of lower silicides (Mo,W)₅Si₃ and the decrease in the layer of higher silicide MoSi₂ depending on the oxidation temperature were determined. It was found that the stability of the MoSi₂–W system exceeds the stability of the MoSi₂–Mo and WSi₂–W.

The influence of alloying additions of rhenium on the strength characteristics of tungsten-rhenium alloys was studied. It is shown that additions of rhenium injected into tungsten during co-deposition from the gas phase of their fluorides lead to the increase in bending strength from ∼ 340 MPa for tungsten to ∼ 800 MPa for tungsten-rhenium alloys with the rhenium content of ∼ 11 wt.%. In this case, the brittle-plastic transition temperature Т_х is decreased from 600 to ∼ 200°С.

The barrier tightly adherent coatings based on refractory metals and applied in accordance with the developed technologies on the Zr or V cladding of fuel elements are obtained. The coatings provide their protection from the impact of nuclear fuel based on uranium carbides or uranium metal and increase their reliability.

Strength characteristics of uranium dioxide particles coated with chromium, vanadium, Al₂O₃–Cr and Al₂O₃–V alloy in the temperature range of 20 – 900°Сwere studied by testing for diametrical compression between two parallel planes. It is shown that the strength of the particles depends on the thickness and material of the coating, strength of the fuel kernel, loading rate and test temperature. The strength of particles is increased together with the coating thickness and test temperature reaching the maximum value at 700 – 900°С. The nature of coating rupture varies from intercrystalline (20 – 150°С) to plastic (650 – 900°С). The method for statistical processing of test results and probabilistic estimation of particle strength is proposed. It is shown that the stability of coated particles is well described by the Weibull probabilistic dependence, which makes it possible to predict the destruction of particles under any load. The probabilistic estimation of the particle strength dependence on the load at different temperature values was carried out.

The research on obtaining a cavitation-resistant coating based on boron carbide was carried out using hydrogen reduction of boron trichloride BCl₃ and toluene C₇H₈. The experimental results on determining the magnitude of erosion damage show that the specimen with the boron carbide based coating undergoes 2.5 times less cavitation wear than austenitic steel.

Sublimation source

The source of Si–Ge–B and Si–Ge–P atoms on Mo and W substrates for sublimation deposition of Si_1–x–Ge_x(0.01 ≤ x ≤ 0.05) doped with B and P was obtained for the first time using the gas-phase method. The source allows expanding the range of applied substances, ranges of operating temperatures for evaporation and vapor pressures of Si–Ge–B and Si–Ge–P, which significantly improves the operational properties and deposition effectiveness.

It is shown that the obtained multilayer heteroepitaxial structure on the single-crystal Si and Si_0.97–Ge_0.03:B(∼ 10¹⁸ cm⁻³) substrates with the Si_0.95–Ge_0.05:B(∼ 10¹⁸ cm⁻³) buffer layer and Si_0.95–Ge_0.05:B(10¹⁷ – 10¹⁸ cm⁻³) and Si_0.99–Ge_0.01:B(∼ 10¹⁸ cm⁻³) upper epitaxial layers are characterized by photo-EMF and photosensitivity in the near-IR radiation region at the wavelength of ∼ 0.8 – 1 μm, which is important for further development of optoelectronic devices.

The structure and composition of the carbide-chromium coatings obtained from the OCL "Barhos", as well as their corrosion and erosion resistance, depending on the deposition process parameters, were studied. For the first time, the formation of two-level layered structure of carbide-chromium coating and the effect of reducing the surface roughness for the products after coating deposition from R_a = 0.7 – 1.2 μm to R_a = 0.4 – 0.6 μm were revealed. It is found that the increased coating resistance can be explained by the nano-size of coating structural elements and their layered structure, and the maximum values of adhesion, corrosion and erosion resistance are achieved at the deposition temperatures of 500 – 550°С.
