The aim of the work is to study the effect of silver doping on the structure and mechanical properties of porous titanium nickelide alloys obtained by self-propagating high-temperature synthesis (SHS). The structure of the samples was studied using X-ray diffraction analysis, scanning and transmission electron microscopy. The mechanical properties of X X porous alloys were studied in compression tests. An increase in the volume fraction of the B19' martensitic phase, intermetallic compounds based on the Ti 2 Ni and a decrease in the volume fraction of austenite with the B2 structure with an increase in the silver content were established. An increase in the plasticity of porous titanium nickelide alloys with an increase in the concentration of silver in the composition while maintaining the ultimate strength was revealed.

In this work, the effect of technological modes of applying coatings based on calcium-phosphate powder on substrates of titanium nickelide alloys was studied. Compacted powders of calcium phosphates were used as targets. The optimal modes of coating deposition were selected and the deposition rates were determined. The structure, morphology, and phase composition of the alloy surfaces were studied by X-ray diffraction analysis and scanning electron microscopy.X X According to the results of the atomic force microscopy, a significant decrease in surface roughness was found depending on the thickness of the calcium-phosphate layer. When assessing the cytocompatibility of the alloys, a correlation was found between the number of viable mesenchymal stromal cell cultures and the thickness of the Ca -P coating. When the coating thickness increases, the viability coefficient of cell cultures increases either.
