Approximate calculation relations are obtained to find the breakdown time, Td, breakdown (discharge) voltage, Ud, and breakdown strength, Ed of a strong electric field for this DEDS, averaged over a minimum length of lmin ≥ 1 m of these gaps. The proposed engineering approach to determining the values of Td, Ud, and Ed is based on the results of an approximate calculation in a long air gap of a point-to-plane DEDS of a sharply inhomogeneous strong electromagnetic field that produces a spherical zone with a radius ri of active impact ionization of its atmospheric air by electrons. This occurs near the lower sharp edge of the upper potential electrode point of the DEDS, wherefrom a positive discharge leader develops towards the lower grounded electrode plane of the DEDS.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 6","pages":"912 - 924"},"PeriodicalIF":0.7,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706159","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}

Based on the given model, the system of differential equations was obtained regarding the time dependences of amplitudes of the probability of finding an electron on different centers of a pentamer. This model was used to describe the pentamers of linear and square-planar configurations. For those two types of the pentamer configuration, the numerical calculations were performed at different values of model parameters. The proposed model is characterized by the fact that the centers of the nanocluster are considered as weakly tunnel-coupled, and the electron-vibrational coupling with the ligand environment on each of its centers plays a significant role. Moreover, tunneling is taken into account only between the nearest centers of the nanocluster, while the cluster centers are considered equivalent. The control role of an external electric field was revealed so that the variations of its intensity amplitude and frequency allowed for realizing the various electron localization regimes in the pentamer nanocluster. By setting up the values of those electric field parameters, the duration of the full localization of an electron at a certain cluster center (or centers) was regulated as was the rate of switching the localization of an electron to another cluster center (or centers) and the form of the overall distribution of electron density in the nanocluster.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 6","pages":"942 - 950"},"PeriodicalIF":0.7,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706242","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 coating was deposited on the sample by the electron beam technique. The thickness of the coating was approximately 2 μm. The treatment of the system samples was carried out by three pulses of compression plasma flows in a nitrogen atmosphere (energy density absorbed by the surface varied from 26 to 43 J/cm2 per pulse). The phase and elemental composition, structure, surface roughness, and microhardness were investigated. It has been established that the action of compression plasma flows on Ag/Ti–6Al–4V system results in the formation of TiAg, Ag, and δ-TiN in the surface alloyed layer. Increase of the energy absorbed by the surface during plasma impact (26–43 J/cm2) led to a decrease in Ag concentration (20.0–6.9 wt %) in the analyzed layer. The change of phase composition and structure results in modification of the microhardness. A microhardness increase up to 4.8 GPa (1.3 times in comparison with initial Ti–6Al–4V alloy) was found after compression plasma flows’ treatment at 43 J/cm2.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 5","pages":"686 - 691"},"PeriodicalIF":0.7,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341259","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}

Using two variables of normal stress (σv/MPa) and different concentration of fiber content (r/%), a computational experiment was carried out. During the experiment, the properties of fiber-reinforced concrete samples with coconut, reed and steel fibers and reference concrete samples for tension, bending and compression were compared. The experiments led to the conclusion that all types of fibers can improve the mechanical properties of structural concrete. An analysis of the test results showed that the best way to improve the mechanical properties of concrete is to add 2% reed or coconut fiber and 1.5% steel to the concrete mixture. During the experiments, it was found that due to the impact strength of metal fibers, the compressive results of samples with steel fiber are much higher than for samples with plant fibers, while the bending strength and tensile strength are higher for samples with non-metal fibers. According to the results of the experiments, the relationship between the mechanical stress of fiber-reinforced concrete is as follows: concrete with steel fibers > concrete with reed fibers > concrete with coconut fibers.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 5","pages":"655 - 664"},"PeriodicalIF":0.7,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341264","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}
