Abstract A beam of accelerated C 60 ions is used to deposit superhard (∼50 GPa) carbon films that exhibit high index plasticity (∼0.13–0.14) and conductivity (up 3000 S m −1 ). Transmission electron microscopy, Raman spectroscopy x-ray photoelectron are subsequently study the microstructure bond character deposited films. The consist textured graphite nanocrystals diamond-like amorphous (DLC). graphene plane aligned perpendicular film surface. It shown sp 2 bonds dominate in percentage 3...
Ultra-thin carbon-based nanocomposite coatings comprised of graphite nanocrystals embedded in diamond-like carbon (DLC) matrix were deposited on stainless steel substrates by the C<sub>60</sub>ion beam method, as a wear protective coating.
The phenomenon of surface self-healing in C60-based polymer coatings deposited by ion-beam assisted physical vapor deposition was investigated. Nanoindentation the led to formation a protrusion rather than an indent. This accompanied abnormal shape force-distance curve, where unloading curve lies above loading due additional force applied pulling indenter out media. exhibited nanocomposite structure that strongly affected ratio C60 ion and molecular beam intensities during deposition. also...

In this work, we present results on study of DLC, nanocomposite and nanocrystal nanographite films synthesized utilizing mass-separated beam C60-ions with energy in range from 2 to 6 keV (energy dispersions approximately 1 keV) at Ts the RT - 873 K. The dependence structure, mechanical electrical properties ion substrate temperature was revealed. We demonstrate a possibility control orientation base planes grains during film growth. defined. It is discussed mechanisms oriented growth for...

By methods of scanning tunnelling microscopy and spectroscopy the surface structure electronic properties carbon films deposited from mass-separated beam accelerated C60 ions are studied. The main feature relief is presence quasi-periodic globular structures with characteristic sizes 2–4 nm a height about 1 nm. They lined up in straight rows curved chains on entire film typical scale 3–4 nm. Tunnelling spectra show that consists nanoscale regions wide band gap (4–4.6 eV, p-type conductivity)...
In present work we developed and tested model anode-supported planar solid oxide fuel cells. We used commercially available 2-layered (current-collector functional) anode supports. Thin-film electrolyte layer based on 8 mol.% yttria-stabilized zirconia (YSZ) was produced by aerosol deposition method using converging-diverging (de Laval) type nozzle. To provide the fabrication of pinhole-free gas-tight thin-film coatings, pre-treatment procedure initial powders developed. The optimal...

Hard wear-resistant carbon coatings were deposited from accelerated C60 ions at temperatures of 200 and 300°C.
