This work aims at reducing abrasion between titanium alloy parts, such as drive shafts and support pairs used in aviation. Three different NiCrBSi coatings, Ni40, Ni50, Ni60, are prepared on surfaces of Ti6Al4V by laser cladding. The microstructural mechanical properties these coatings analyzed scanning electron microscope (SEM) a microhardness tester. tribological the undergoing friction with tested using wear testing machine. results show that Vickers hardnesses Ni60 490 HV0.3, 609 708...
A handful of bis/tetra-phosphonate calix[4]pyrroles with recognition sites embedding in hydrophobic cavitands were evaluated for the first time as ionophores polymeric membrane Ach+-selective electrodes. Highly selective potentiometric Ach+ could be achieved over its analogues, especially Ch+, which differs only by an acetate tail from Ach+. The superior performance proposed ISEs might ascribed to a dual-site binding mode, trimethylammonium head and accommodated phosphonate group-bridged...
The radio frequency power transfer efficiency is experimentally and numerically investigated in an inductively coupled negative hydrogen ion source. discharge operated a low pressure range of 0.1–3 Pa at driving 2 MHz applied up to 6 kW. In the experiment, value determined by measuring current through antenna coil both with without operation. Fundamental properties, such as electron density effective temperature, are obtained means Langmuir probe. effect turns, N, also studied 5–9 turns. It...
Inverse problem of manufacturing is studied under a framework high performance components with functional surface layer, where controllable generation integrity emphasized due to its pivotal role determining final performance. Surface modification techniques capable controlling are utilized verify such manufacturing, by which the desired for can be more effectively achieved as reducing material and geometry constraints otherwise unobtainable during conventional machining processes. Here,...
An efficient silver-catalyzed method of decarboxylative radical allylation α,α-difluoroarylacetic acids has been developed to construct CF<sub>2</sub>–allyl bonds in aqueous CH<sub>3</sub>CN solution under the mild reaction conditions.
In aviation, the relative sliding between titanium alloy components causes varying degrees of wear. This work aimed at reducing abrasion parts and improving their service life. Three different Ni-based coatings, WC-10Ni, Ni45, NiCr are sprayed on surface Ti6Al4V by HVOF. Test results mechanical tribological properties such coatings show that hardness Ni45 673 HV0.1 438 HV0.1, respectively, which lower than WC-10Ni coating. When subjected to a high load, suffer cracking flat particle...
This paper presents the evolution of electronegativity with applied power during E to H mode transition in a radio frequency (rf) inductively coupled plasma (ICP) mixture Ar and O 2 . The densities negative ion electron, as well their ratio, i.e. , electronegativity, are measured function by laser photo-detachment combined microwave resonance probe, under different pressures contents. Meanwhile, optical emission intensities at 750.4 nm 844.6 monitored via spectrograph. It was found that...
Four hydrogen bond-based macrocyclic and tripodal neutral receptors with increasing conformational complementarity sulfate were used for the first time as ionophores to develop polymeric membrane sulfate-selective electrodes. Optimizing composition such ionophores, lipophilic additives, plasticizers yielded ISEs which showed Nernstian response best selectivity so far improved detection limits (a slope of −29.8 mV/dec in linear range 1 × 10–6–1 10–1 M a limit 5 10–7 M), led success...

The effects of gas pressure and component on the power transfer efficiency η transition threshold Pth during E–H mode in inductively coupled plasmas are studied. evolutions pure Ar Ar/O2 discharges similar, i.e., E-mode discharge, slightly increases with raising applied (η is below 30%), whereas, an abruptly upward jump nearly two to four times for occurs when discharge transits H-mode, then monotonously increasing power. In addition, as rises, rapidly first slowly discharge. However,...
