“…The Mo here can be from the molybdenum screens of the vacuum furnace. The simulation of the RBS spectra with the NBS code [7] shows that the experimental spectra correspond to a backward scattering on a lay ered structure, of which the first layer has the thickness of 0.5 μm and consists of Mo 0.5 Ti, and the second layer has the thickness of 1 μm and the composition Mo 0.3 Ti. The second layer may have a more complex composition and may also contain Ni, which is present in the equiatomic initial alloy TiNi.…”

With the help of the PIXE and RBS methods, the elemental composition of a ceramic coating on Zr alloy, surface layers of heat treated TiNi alloy, and Ar + implanted pyrolytic graphite is investigated. It is shown that the PIXE and RBS methods are complementary and their combined use can provide additional information on the elemental composition of the surface layers. It was determined that the microarc oxida tion of Zr alloy in an electrolyte with addition of ultrafine Y 2 O 3 powder leads to introduction of Y in the sub strate material. An effect of the surface segregation of Ti was found in TiNi alloy after the heat treatment.

“…The elemental analysis was produced by the Rutherford backscattering (RBS) of He + ions with the energy 2 MeV at an angle of 160°. Computer simulation of the RBS spectra was performed using the NBS program [16]. It is found that before irradiation the carbon and silicon concentrations in the surface layer were approx imately 49.3%, moreover, there is argon (~1.4%) in the composition, and the situation was similar after irradia tion [4].…”

The results of experimental study and computer simulation of SG P 0.1 carbon ceramic com posite sputtering under 30 keV Ar + ion irradiation at normal incidence are presented. A comparison with the simulation data shows that taking into account the nanometric wave like relief well describes an approxi mately threefold increase in the sputtering yield observed in the experiment in comparison to the smooth sur face calculation.

“…However, even amorphous carbon nitride layers may have suitable physical properties for the use in many tribological applications, for instance as protective coatings. A wide variety of elaboration techniques have been used such as reactive sputtering, chemical vapour deposition, pyrolysis of organic materials, laser deposition and ion implantations [2][3][4][5][6][7][8]. So far, whatever the technique employed, mixed phase layers are quite often obtained and it remains very difficult to achieve fully crystalline phase formation.…”
