It is shown that with increasing test temperature, the plastisity of steel decreases. Based on the analysis results, it was concluded that a decrease in the ductility of steel with an increase in the test temperature may be due to a change in the fracture mechanism under the action of shear stresses, which was facilitated by local increase in the porosity of the material as a result of grains accommodation processes of the rotational type.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128441794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on new robot-assisted technologies for plasma coating of medical implants. This includes robotic microplasma spraying of Zr coatings on biomedical Ti implants. The design of the movement of the robot arm provides a coordinated and individual operation of the plasma coating. Scanning electron microscopy was used to analyse the structure of the coatings. The possibility of controlling the porosity of Zr microplasma coatings in the range from 2.8% to 20.3% by changing the parameters of microplasma deposition was established.

The films were obtained by deposition from “metal plasma” formed during ablation of the copper anode of the PF installation. The films were deposited in the atmosphere of the plasma-forming gas argon at a pressure of ~ 1 Torr. The film uniformity was controlled by measuring the transmission spectrum in the middle and at the edge of the glass plate and was ~ 10%. Transmission spectra of films on glass substrates were measured in the range of 0.3-1.0 µ at temperature 300K. The transmission spectrum of Cu films is mainly determined by light scattering on small particles < 0.3 µ. Good adhesion of films is due to the formation of a transition layer on the surface of glass plates. Depending on the number of plasma pulses optical copper films were obtained as dielectric and also electrically conductive.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116987117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surface alloys have a significant advantage over coatings since they provide the highest level of adhesion. Heat resistant alloys based on nickel-aluminum are widely used in engineering due to their low density, combination of high thermal conductivity and fracture strength at high temperatures. The application of the Ni and Al multilayer structure for the formation of the surface Ni-Al alloy by the method of liquid-phase mixing is studied. The effect of geometry parameters such as thicknesses of layers is considered. At a certain ratio of effective layer thicknesses the melting threshold of the multilayer structure is minimal.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117030986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emerging trend towards miniaturization of the various devices such as unmanned aerial vehicles requires deposition of thin and light-weight films that combine magnetic and dielectric properties. In this work we propose an advanced approach to formation of such thin magneto-dielectric coatings – by the use of a fore-vacuum plasma-cathode electron source. Using the electron-beam evaporation of dielectric (alumina ceramics) and magnetic targets in medium vacuum (several Pa), we create dense multicomponent plasma, which provides the flux of the particles of gas and the target materials, allowing to deposit magneto-dielectric coatings on a metallic substrate with a very high deposition rate (approximately microns per minute), and high degree of coating uniformity. We present here our preliminary results on the electron-beam evaporation of ceramic and magnetic targets.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117217413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method is based on the operation of the Marx generator of a coaxial design in the intermediate inductive storage mode. An analysis of the operation of the circuit is made. It is shown that the inductances Ls and the capacitance of the Cs steps relative to the conductive screen distributed over the steps of the Marx generator form a forming line, the energy of which, when using a current chopper, is stored in the circuit inductance. As a result, an impulse of duration $taucong$ 2N·(Ls·CS)1/2, where $N$ is the number of stages of the Marx generator, is formed on the active load (e-beam diode). The results of calculations and test experiments during the operation of the Marx generator located in a conducting screen with a current chopper based on an electric explosion of conductors (EEC) are presented.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125277915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
