In this paper, we describe the methods and results of mathematical simulation of the interaction between cosmic rays and detectors. This has increased the accuracy of determining the level of radiation impact on materials and components of spacecraft. The application of the results obtained in the design and production of advanced spacecraft will s...

Investigations of the influence of various modes of electrolysis on the speed of processes of electrodeposition of metals are conducted. On the basis of theoretical investigations, the main potential opportunities for process intensification when using an pulsed current for processes whose speed is defined by mass transfer and charge transfer are d...

The manufacturing technology of the composite filler rods based on babbit B83 by extrusion is developed. The filler rods have a uniform distribution of the high-strength reinforcing particles (silicon carbide) and the modified rock shungite. It is shown that the hardness and density values of the composite filler rods correspond to the properties o...

Design, manufacture, and test results are presented for laminated metal-polymeric hybrid fragments of a wing panel made of high-strength aluminum-lithium alloy V-1469T1 and of single-directed laminated aluminum fiberglass SIAL-1-1R. It is shown that the principle “material–technology–structure” can be implemented, and we demonstrate it by example o...

A method is developed for the preparation of mixed pentoxide Nb2(1–y)Ta2yO5 by rapid coprecipitation of a mixture of hydroxides of niobium and tantalum from a solution of hydrofluoric acid by ammonia water, followed by purification and calcination of the precipitate. The proposed method allows obtaining a homogeneously mixed pentoxide of niobium an...

The study aimed at revealing the main interaction regularities of powder mixtures of tungsten with a polymeric polytetrafluoroethylene matrix (PTFE) in shock-wave consolidation in cylindrical recovery fixtures. Three powder compositions based on tungsten and Teflon were subjected to shock-wave treatment: a two-component one (W + PTFE) and ones with...

The mechanism and the kinetics of the oxidation in an air flow of powdery Nb–Si eutectic alloy containing (wt %) 93.0 Nb, 6.7 Si, and 0.27 B are studied by X-ray diffraction (XRD), thermogravimetric (TG), and differential thermal analysis (DTA). The oxidation of alloy proceeds through three stages. At the first stage (600–923 K), the oxidation of a...

Thin films of Mo(Ni)Sex are synthesized using pulsed laser deposition (PLD) in a special mode of operation in which the laser ablation of a Mo(Ni)Se2 target releases a mixed deposition flux consisting of atomic Mo, Ni, and Se and Mo droplets. The size of deposited Mo particles is in the range of 20–100 nm. Incorporation of amorphous carbon phase (a...
