Opis:: Temporal and spatial distribution of temperature field was studied in operating acousto-optic devices on base of large-size paratellurite crystals. The study was carried out in real time by means of thermal imaging technique. Dynamics of heat release in a hot deflector and a hot tunable filter was examined at different frequencies and driving electric power levels applied to piezoelectric transducers. The study was also based on measurements of standing wave ratio and analysis of the Smith charts.

Opis:: Results of structure, phase composition, physical and mechanical properties and tribological properties investigations of nitride high-entropy coatings (TiZrHfVNb)N are presented in the paper. Proton microbeam (μ-PIXE), X-ray diffraction method, including method of X-ray strains measurements, energy dispersive X-ray spectroscopy and scanning electron microscopy analysis, microhardness testing and nanoindentation were used. Thermal annealing (t=600°C) influence on defect profiles, structure and element distribution in the coatings was investigated. It was found that thermal treatment of coatings leads to changing of defect profiles and to element redistribution. Also we can say that it influences less on grain size changing. Investigated (TiZrHfVNb)N coatings demonstrate high values of hardness and excellent wear resistance.
