In this work, the mechanical properties and corrosion resistance of Cr-CrN, Ti-TiN, Zr-ZrN, Mo-MoN coatings deposited by physical vapor deposition (PVD) method on Ti-6Al-4V alloy were compared. The phase composition coatings, their hardness fracture in scratch tests determined, structural characteristics also studied using a scanning electron microscope (SEM) transmission (TEM). diffraction spectra made an automatic X-ray diffractometer. value adhesive component friction coefficient fadh...
The article presents the results of a comparison wear resistance coatings with two-layer architecture (adhesion layer–wear-resistant layer) Zr-ZrN, Zr-(Zr,Ti)N, Zr,Hf-(Zr,Hf)N, Zr,Nb-(Zr,Nb)N, Zr,Hf-(Ti,Zr,Hf)N, and Zr,Nb-(Ti,Zr,Nb)N coatings, deposited on titanium alloy substrate. was studied using two different counterbodies: Al2O3 steel. When in contact counterbodies, best demonstrated by samples Zr,Hf-(Zr,Hf)N Zr,Nb-(Zr,Nb,Ti)N coatings. In tests conducted steel counterbody, Zr-ZrN...
This article compares the antibacterial properties of single-layer (Ag) and two-layer (Ag,Cu) coatings deposited onto a polypropylene mesh (endoprostheses for hernioplasty) in various gaseous environments (argon or nitrogen) via magnetron sputtering. The microstructure elemental composition were studied SEM TEM. antimicrobial activity sterile samples was investigated using Staphylococcus aureus strain. To prevent overheating polymer during coating process, it is advisable to carry out pulse...
In this paper a detailed study of the (ZrO 2 ) 1‐ x (Y O 3 ( =0.025–0.15), 1 ‐x (Sc = 0.06 – 0.11) and x‐y y =0.07 0.11; =0.01 0.04) solid solution crystals grown by skull melting technique is presented. The structure, phase composition, ion conductivity obtained were investigated X‐ray diffraction, transmission electron microscopy, Raman scattering spectroscopy, impedance spectroscopy. Maximum as observed for compositions containing 10 mol% stabilizing oxide, 10Sc SZ ~3 times higher than...
Single-mode Er–Yb fibers with the core based on a phosphorosilicate glass matrix (up to 6.5 mol.% P2O5) highly doped fluorine 0.9 wt.%) were fabricated using an all-gas-phase modified chemical vapor deposition method. The numerical aperture was in range of 0.07–0.08 relative pure silica, which allowed us increase single-mode diameter up 20 μm. slope efficiency lasers reached 34% launched pump power.
We introduce an approach toward the synthesis of micro- and nanostructures under nonequilibrium microwave discharges within metal–dielectric powder mixtures induced by powerful gyrotron radiation. A new plasma-chemical reactor capable sustaining a discharge regime with afterglow phase order magnitude longer than pulse duration was constructed for these experiments. In conditions such discharge, plasma-induced exothermic chemical reactions leading to various compounds were initiated. The...
Abstract This work is a study of the effect co-doping (ZrO2)0.9(Sc2O3)0.1 solid solution with yttria and/or ceria on phase composition, local structure and transport properties crystals. The crystals were grown using directional melt crystallization in cold crucible. We show that does not stabilize high-temperature cubic entire crystal bulk, unlike co-doping. Ceria increases their conductivity, whereas addition 1 mol.% tangibly reduces conductivity. Equimolar changes conductivity but...
