Synthesis, X-ray phase analysis, electron microscopy and investigations of the thermoelectric and thermal properties of nanocrystalline copper sulfide alloys contained sodium are presented. At room temperature, the alloys are a mixture of three phases of copper sulfide - the monoclinic phase of Na2Cu4S3 , the hexagonal phase of Cu2S and the cubic phase of Cu9S5 (digenite). The predominant phase is Na2Cu4S3 (with content from 57 to 85 volume %). The particle sizes in the compacted samples lie in the range from 20 to 400 nm. …

The paper presents the results of investigations of the structure and phase composition of titanium boride coatings deposited by magnetron sputtering from a target of a complex composition onto a steel substrate. The target for magnetron sputtering was obtained by sintering boron carbide and titanium powders. The structure and elemental composition of the coating were studied using X-ray diffractometry (XRD), scanning electron microscopy (SEM) and the energy-dispersive spectral (EDS). It was established that the coatin g structure is a mixture of Ti2B5 and TiB12 phases with the total boron content of ≈ 80 at %, which …
