The paper focuses on the dual high-power impulse magnetron sputtering of TiAlN coatings using short pulses high power delivered to target. surface morphology, elemental composition, phase hardness, wear resistance, and adhesive strength with different Al contents were investigated WC-Co substrates. heat resistance coating was determined synchrotron X-ray diffraction. hardness a low content ranged from 17 30 GPa, its rate varied between 1.8∙10-6 4.9∙10-6 mm3·N-1·m-1 depending substrate bias...
In this work, a-C:H:SiOx coatings with thicknesses of 300–1400 nm were synthesized by plasma assisted chemical vapor deposition on the surface titanium alloy Ti-6Al-4 V. The thickness dependence roughness was determined laser profilometry. This is described a parabolic function. filtration potential method showed that in an acidic environment (pH = 3), increase coating accompanied decrease zeta from +40 to −24 mV. more neutral 6–7.8), varies −30 −40 Potentiodynamic polarization curves...
Abstract The article deals with the plasma‐assisted chemical vapor deposition of 0.3–1.4 μm thick a‐C:H:SiO x films in a mixture argon and polyphenylmethylsiloxane onto Ti–6Al–4V alloy substrate, which is often used as an implant material. film structure studied by Fourier‐transform infrared Raman spectroscopies. pull‐off adhesion test assesses adhesive strength films, ball‐on‐disk method employed to measure their wear rate friction coefficient. According these studies, are highly have low...
The properties of SiOx doped amorphous hydrogenated carbon (a-C:H:SiOx) films greatly depend on the deposition parameters, in particular, ion bombardment intensity during film growth. In this work, a magnetic field created by an external coil was used for plasma confinement and control process enhanced chemical vapor a-C:H:SiOx films. structure, surface morphology, mechanical obtained were studied using Raman spectroscopy, atomic force microscopy, nanoindentation, respectively. This work...
The study attempts to clarify whether the short pulse electric strength (SPES) of a millimeter plane-parallel vacuum gap depends on properties electrode materials such as microhardness, work function, and crystallographic structure. Of all considered, confirms only influence structure SPES, was found earlier for dc voltage gaps several tense micrometers. Despite well-known fact breakdown ignition at cathode, mechanism triggering this is not necessarily related one electrodes.
Abstract The paper presents the results of a study modes dual deep oscillation magnetron sputtering. use packet pulse discharge power supply allowed to provide high density on surface Al target 60–500 W·cm −2 and ion current substrate 4–20 mA·cm during duration macro – 1 ms. In addition parameters pulsed supply, way connecting source sputtering system vacuum chamber changed experiments. Targets were isolated from or alternately connected it. A change in connection method led anode area such...
Background. A shortage of donor organs is one the urgent problems transplantology. Despite current level technology, there are a number difficult barriers to overcome. Because high demand for assisted circulatory devices, work caused by creation most physiological and biocompatible model apparatus, exceptional relevance provided.Aim. To evaluate haemolytic properties auxiliary apparatus based on disk-type pump.Methods. hydrodynamic bench was created conduct haemolysis tests pump. The...
This paper focuses on the surface modification of Ti-6Al-4V alloy substrate via a-C:H:SiOx coating deposition. Research results concern structure, investigated using transmission electron microscopy and in vitro endothelization to study coating. Based analysis atomic radial distribution function, a model is proposed for short-range order structure coating, chemical bonds (C–O, C–C, Si–C, Si–O, Si–Si) are identified. It shown that does not possess prolonged cytotoxicity relation EA.hy926...
