The structure and properties of materials based on alloys and thin films of niobium with tin were investigated by means of differential thermal (DTA), X-ray, energy dispersive analysis. The synthesis conditions and temperature ranges of oxidation resistance were determined from the DTA data. The study of the stability of films in the air was carried out when keeping the films at room temperature for 1-3 months and when heating them at 100 and 250 ° C for 2 hours. Alloys were obtained by direct fusion of the components at 800 ° C with further grinding, pressing, and sintering at 500 ° C for 100 hours. The phase composition of the alloys was investigated by the X-ray phase analysis. X-ray phase analysis of thin films showed that thermodynamically most stable compounds in the system are usually deposited on the surface of the substrate during deposition from the gas phase. The study of the surface relief using an AFM atomic force microscope showed that the surface of the films remains unchanged when exposed to a normal temperature of up to 3 months. The resistance values determined by the four-probe method demonstrated the increase of resistance of the films by about 20-30% when compared to compact substances.
