The article presents a method of producing on the surface of the ceramic substrate on the basis of α-Al2O3 quasi-periodicals and nanostructure. It is shown that a laser beam on the surface of the ceramic substrate based on α-Al2O3 convectional moving as the Rayleigh-Benara can be excited. One of the areas of industrial application in which nanostructures can be used is semiconductor optoelectronics...
The results of investigation of the sheet resistance of alumina ceramic as a function of the fluence of implanted metal ions are presented. Tantalum ions with the average energy about 145keV were used in experiments. Estimation of the sheet resistance was performed from analysis of volt–ampere characteristics by measuring the leakage current at a voltage between 100V and several kilovolts, which was...
The surface microstructure of Mn-Zn-ferrite products after low-energy electron beam treatment was investigated. It was shown, that depending on the treatment time the microstructure with a different phase composition is formed on the surface which leads to surface planarization, lessen intergranular and intragranular pores and interstice reduction. It improves quality and firmness to destruction of...
The possibility of improvement of Mn-Zn-ferrite microstructure surface by the low-energy electron beam treatment in the oxygenic ambience was investigated. It was shown, that the treatment of surface of a Mn-Zn-ferrite item by a low-energy electron beam in the oxygenic ambience makes the surface even, lessen intergranular and intragranular pores and interstice reduction. It improves quality and firmness...
Results of research of near-surface layer of aluminum oxide ceramics substrates for microwave hybrid IC's (MHIC's) are presented. Layers were produced by treatment of laser beam (1.06 μm wavelength) exposure — laser treatment (LT). The composition and structure of near-surface layer were researched by methods of electron microscopy and IR Fourier spectroscopy. It was shown that in case of LT the chevron...
Results of research of near-surface layer of aluminum oxide ceramics thin plates were presented. Layers were produced by treatment of electron beam (5 keV energy) — electron beam treatment (EBT) — and laser beam (1.06 um wavelength) exposure — laser treatment (LT). The composition and structure of near-surface layer were researched by methods of electron microscopy, X-ray structure analysis and IR...
