Application of HF discharge for nitriding of various surfaces
The experimental results on nitriding of flat and inner surfaces of cylindrical specimens made from Ti and stainless steel (SS) are presented. The HF discharge was applied for nitriding with and without the application of an external magnetic field. The changes of specimensβ properties dependent on process conditions were investigated
Production of metal and dielectric films in a combined RF and arc discharge
In the presentation we investigate the possibilities to deposit metallic and dielectric films on metal and dielectric materials by means of vacuum technology with application of high frequency (RF) electric fields. As a base-model the device βBulat-6β was used with proper arc evaporators. The leading-in of a RF power (3 kW, f=1-10 MHz) was realized by connecting the RF generator to a planyclic system of the device. Before the film deposition the samples were conditioned by plasma of RF discharge (without arc discharge) at the gas pressure p=10β»β΄ Torr. The multi-layer coatings of the type Cr-CrN, Cr-TiN-Cr, Ti-TiN-Ti deposited on complicated shape wares of aluminum alloys had a microhardness value up to 2000 kg/mmΒ². The properties of such coatings were studied depending on the vacuum conditions in the process of deposition. Taking into account the potential well developing under RF field, the experiments were provided on depositing the drip-free coatings by placing the wares in that region of vacuum chamber, which is closed from the direct ingress of particles from the arc vaporizer. The AlβOβ and AlN dielectric coatings were obtained and their characteristics were studied by using the electron microscope technique.ΠΠΈΠ²ΡΠ°Π»ΠΈΡΡ ΠΌΠΎΠΆΠ»ΠΈΠ²ΠΎΡΡΡ Π½Π°Π½Π΅ΡΠ΅Π½Π½Ρ ΠΌΠ΅ΡΠ°Π»Π΅Π²ΠΈΡ

Elite burial of the golden horde era in the samara volga region: Man, horses and ritual complex
The article presents some preliminary results of a comprehensive study of a unique archaeological site of the Golden Horde time - a single burial mound Svetloe Pole III, excavated in the Samara region in 2020.In the only burial, despite the destruction, extraordinary objects have been preserved: a massive (gilded) bronze belt overlay with the image of a dragon, a horn pommel depicting a bird of prey gnawing at a large bird - possibly a bustard; gold earrings and stripes into clothes, coins, iron arrowheads (some of them gilded), etc.The sub-kurgan area was surrounded by a wooden ring structure 15 m in diameter, on the eastern side of which there was a sacrificial complex with 14 skulls of horses without lower jaws.The anthropological study showed that the buried man, 50-60 years old, of the Mongoloid anthropological type, had numerous pathologies.Interesting paleozoological observations were made when analyzing bone remains of the animals found not only on the sacrificial site, but also in the filling of the mound
