HAXPES is capable of producing both surface and bulk features of the alloys. All the core levels such as 2s, 2p, 3s, 3p of both Fe and Ni were investigated and multiple features corresponding bulk and surface were observed. Alloy surfaces were found to have predominantly Fe oxides such as FeO and Fe2O3 compared to Ni oxides indicating the segregation of Fe to the surface. The 3p core levels of Fe and Ni exhibit exchange splitting and spin orbit splitting respectively with lower surface oxide contribution due to the enhanced bulk sensitivity at higher kinetic energies. Fe 2s core level exhibits correlation induced multiplet features.

Various modes of electron beam processing (accelerating voltage and number of pulses) are considered sequentially, and a characteristic phase composition for each mode is established. The accelerating voltage for the threshold mode of electron beam processing, at which melting of the Ti and LaB6 layers in the multilayer system begins, is determined. In this case, as a result of melting-crystallization, a transition of the LaB6 layers from the initially amorphous state to the crystalline one and formation of the TiB2 phase are observed. The electron beam processing parameters for the optimal mode, at which melting of all deposited Ti and LaB6 layers in the multilayer system occurs, are also determined. In this mode, intensive formation of the LaB6 and TiB2 phases is observed. And the mode of intensive melting, in which melting occurs not only for the multilayer system, but also for a part of the substrate. This mode is characterized by a decrease in the content of the LaB6 and TiB2 phases to a minimum amount. It is shown that the described research method using synchrotron radiation allows one to simultaneously determine several processing modes, using which one can obtain a certain structural-phase state of the surface layer, and, consequently, the necessary properties.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"124 - 128"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613660","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 measured specific surface electrical resistance, the multilayer films under study are divided into three groups with different types of conductivity: low, medium, and high. It is shown that at low frequencies up to 100 Hz and at temperatures above 260 K, the temperature behavior of the real part of the impedance of the planar structure multilayer film/sitall glass-ceramic is determined mainly by the behavior of the sitall plate. At high frequencies, starting from 1 kHz, the temperature behavior of the structure impedance in the entire studied temperature range of 120–420 K has the greatest difference; the higher the frequency and the lower the temperature, the greater these differences. For the planar structure multilayer film/sitall with a low composite layer conductivity, a decrease in the imaginary component of the impedance is observed with increasing temperature at frequencies above 10 kHz. An equivalent electrical circuit for the planar structure multilayer film/sitall is proposed. For effective control of the conductive and frequency properties of the planar structure multilayer film/sitall using alternating electric fields, it is proposed to use multilayer films with low conductivity.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"40 - 47"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614021","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}

Numerical studies of the influence of energy characteristics of the electron-beam effect on the thickness and lifetime of the melt of the multilayer film B/Ti–substrate Ti system are carried out. It is shown that with an increase in the energy density of the LEHCEB the thickness of the melt of the multilayer B/Ti film and its lifetime increase. Based on the modeling results, optimal modes for the formation of multilayer composite coatings are obtained. It is found that for LEHCEB energy densities of 3.5, 4.5, and 5.5 J/cm2, a coating with the following structure is formed: B-Ti surface alloy and a composite coating based on a titanium matrix with a reinforcing phase TiB2; further from the surface there are alternating Ti and B films. For the energy densities of 3.5 and 4.5 J/cm2 melting of the Ti substrate does not occur; therefore, for these modes, the martensitic structure of the substrate surface is preserved. Complete melting of the multilayer B/Ti film–Ti substrate system occurs at LEHCEB energy densities greater than 8.5 J/cm2.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"100 - 104"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613658","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}

It is shown that the surface relief and the magnetic structure of the composite films have a significant effect on the resonance field and the resonance linewidth, especially at large angles φ. It is shown that the resonance linewidth ΔB and the resonance field Br weakly depend on the metal concentration x and the angle φ for films with a granular structure at x = 22–40 at % and strongly depend on x and the angle φ for films with a granular-percolation structure at 49–54 at %. It was found the linewidth ΔB and the resonance field Br increase with increasing angle φ for all films. The presence of two growth regions on the angular dependences of the resonance linewidth ΔB and the resonance field Br is associated with the existence of granular and percolation regions in the composite films. The results of the analysis of the behavior of the concentration and angular dependences of the FMR parameters and relief and magnetic structure of the films indicate a high structural sensitivity of the FMR method in studying the electromagnetic properties of magnetic composite films. Therefore, the FMR phenomenon after improving the technique for measuring the FMR parameters can be used for the structural analysis of composite films.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"20 1","pages":"140 - 145"},"PeriodicalIF":0.4,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613996","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}
