Corrosion Resistance of Nanostructured WC-CoCr Coating with Co-Cr Alloy Binder
Authors: Wang H. , Wang X. , Song X. , Liu X. , Yang T.
Published: April 2023

A nanostructured WC-CoCr coating was fabricated by HVOF spraying using a new type of WC-CoCr powder in which the CoCr exists in the form of a metallic compound. The CoCr powder constituent was prepared by induction melting and mechanical milling. It was then combined with a WC-Co composite nanopowder and the mixture was agglomerated by spray drying and heat treating. The powders and coatings produced were characterized by means of XRD, EDS, and BSE analysis, nanoindentation testing, and potentiodynamic polarization studies. The results show that the presence of the intermetallic CoCr compound makes nanostructured WC-CoCr coatings harder and much more corrosion resistant than conventional WC-Co-Cr coatings in which Cr exists as an unalloyed metal.

Authors: Nakamura J. , Saito H. , Fujita K. , Sakaki K.
Published: April 2023

In this work, pure silicon and Ni-P coated silicon powders were cold sprayed on copper foil. To thicken coating layers, 2-pass and 3-pass coatings were carried out. In the case of Ni-P coated silicon powders, coated anodes show excellent charge-discharge characteristics after two passes. For the pure silicon powders, however, even if a 2-pass operation is performed, the additional attached silicon mass is only 2~3 %. This means that multi-pass spraying is not an effective way to increase the thickness of pure silicon coatings produced by cold spraying.

Authors: Zhang Y. , Jia C. , Jia P. , Zhang J. , Jia Y.
Published: April 2023

B4C-Ni powders ranging in content from 5-60 wt% Ni were fabricated by pressurized hydrogen reduction and deposited on mild carbon steel substrates by air plasma spraying. The microstructure, morphology, and phase composition of the powders and coatings were evaluated by means of SEM and XRD analysis. The influence of Ni content on coating microstructure, fretting wear resistance, hardness, and adhesive strength was investigated in detail. The results show that Ni affects fretting wear resistance, which was found to be highest in the coating with 40 wt% nickel. The B4C-40Ni coating also proved superior in terms hardness, porosity, and friction coefficient, although its adhesive strength was the lowest.

Authors: Xie Y. , Planche M.-P. , Raoelison R.-N. , Verdy C. , Herve P. , Liao H.
Published: April 2023

In this study, cold sprayed Ni is deposited on Al substrates using different gas pressures. Spherical Ni powder was sprayed on cylindrical substrates using argon as the powder carrier and compressed air as the propellant. Coating and splat surfaces and cross-sections were examined, adhesion strength was measured, and particle velocity and temperature were determined through CFD simulations. The results show that denser, more well adhered coatings were obtained under higher propellant pressure. Higher gas pressure increases particle velocity, which intensifies material deformation and the disruption of surface oxides in the impact area, resulting in greater metallurgical bonding between the splats and the substrate. The formation of Ni-Al intermetallic phase at the interface region due to heat treatment was confirmed and its effect on bonding strength is discussed.

Published: April 2023

In plasma spray-physical vapor deposition (PS-PVD), deposition takes place not only from liquid splats, but also from nanosized clusters as well as the vapor phase. As a result, thin, dense, and porous ceramic coatings can be produced for special applications using this method. In this study, columnar-structured YSZ coatings were deposited by PS-PVD on graphite and zirconia substrates and the effect of substrate temperature on coating microstructure was investigated. A deposition mechanism of heterogeneous nucleation is presented based on the observations and findings of the study.
Particle Diagnostics and Coating Properties in Reactive Plasma Spray Process
Authors: Shahien M. , Yamada M. , Fukumoto M.
Published: April 2023

This study investigates the influence of particle temperature and velocity during reactive plasma spraying and the effect of plasma gases on coating properties. Using hydrogen gas with low flow rate was found to be better for reactive plasma spraying of fine Al2O3-AlN mixtures. The H2 gas increased in-flight particle temperature, affecting in-flight vaporization, AlN content, phase transformation, deposition efficiency, and coating thickness. N2 gas, on the other hand, increased particle velocity, thereby reducing particle residence time in the plasma, which affects melting, nitride conversion, and phase transformation.

Published: April 2023

A densidade básica da madeira possui grande importância no controle de qualidade da madeira, devido a fácil determinação e alta correlação com as demais características da madeira, porém esta possui grande variabilidade no sentido longitudinal do tronco. Neste contexto, este trabalho teve como objetivo analisar possíveis otimizações de pontos amostrais ao longo do fuste para a determinação da densidade básica da madeira de Eucalyptus saligna. As árvores foram amostradas em 0%, diâmetro na altura do peito (DAP), 33%, 66% e 100% da altura comercial. A partir da densidade básica pontual foram definidas a densidade média ponderada pelo volume e a densidade média aritmética da árvore. Os resultados demonstraram que não se pode assumir que a densidade média aritmética equivale ao valor da densidade média ponderada pelo volume da madeira de Eucalyptus saligna. Não foi possível determinar um único ponto ótimo de amostragem, ressaltando ainda que a amostragem na altura referente ao DAP não é indicada. Utilizando-se da combinação de dois pontos amostrais, as posições DAP e 33% apresentaram melhor estimativa da densidade básica. Já com três pontos amostrais, a estimativa da densidade básica pode ser obtida com alta precisão, se a amostragem for realizada nas posições DAP, 33% e 66%.

Sampling points optimization along the stem to determine the wood basic density of Eucalyptus saligna
 
ABSTRACT: The wood basic density is important for wood quality control, because it is easy to determine and has high correlation with other wood characteristics, however, basic density has wide variability even in the same tree, mainly along stem longitudinal direction. In this context, this study objective was to analyze different possibilities to sampling points optimization along the stem to determine the wood basic density of Eucalyptus saligna. At the trees were sampled at heights for 0%, diameter at breast height (DBH), 33%, 66% and 100% commercial height. From punctual basic density, average density weighted by volume and arithmetic average density of each tree were defined. The results showed that it is not possible to assumed with statistical certainty that the arithmetic average density accurately estimates the value of Eucalyptus saligna wood weighted average density. Determine a single optimal sampling point was not possible, it is worth mentioning that sampling only at height referring to DBH is not indicated. Using two sample points combination, DBH and 33% positions presented wood basic density best estimate. With three sampling points, density estimate can be obtained with high precision, if sampling is performed in DBH, 33% e 66% positions.

Purpose - The main aim for our research is gaining knowledge of institutional regulation of eco-migration processes in Georgia and, consequently, evaluating the state politics of eco-migration, so as to show off what improving changes can be considered in coming years exactly in the above-mentioned direction.

Design/methodology/approach - The research design is based on the institutional approach to studying migration processes. And the empirical analysis was based on the information collected as a result of the study of archival-state documents and interviews in eco-migrant populated areas. The survey was conducted from March 12 to September 25, 2022.

Findings - Outcome of our research underlines that the development of institutional provision of eco-migration processes has gone through the different stages during the last centenary in Georgia. As if from the side of government appropriate policy is worked out, however, the research showed that it is necessary to establish a systematic and transparent approach to eco-migration and resettlement by the state, the implementation of which should become the prerogative of both the central government and the municipal administration, which should probably happen in the near future.

Originality/value - The scientific novelty of our work is that, for the first time, we studied the historical context of the state policy of eco-migration, the goals of the state policy of eco-migration, the strategy of the state policy of eco-migration and the legal basis of the legal regulation of eco-migration as a process.

Authors:   omsk Polytechnic University,Tomsk, Russia, Surzhikov A.P.
Published: April 2023

The measuring the temperature dependence of the initial permeability was used to study the features of phase and structural transformations in lithium-titanium ferrites as a function of time, heating and cooling rates, and the temperature of liquid-phase sintering under thermal and radiation-thermal heating. Ferrite was synthesized from powder mixture by solid-phase synthesis. A low-melting additive bismuth dioxide was used to obtain the ferrite ceramics by liquid-phase sintering. RT sintering was carried out by heating the samples with a pulsed (1.5–2.0) MeV electron beam. It was established that the additive leads to a less defective state of sintered ferrites, while the action of radiation enhances this effect in the early stages of sintering. The regularities of the influence of the heating and cooling rates of compacted samples on the change in the initial magnetic permeability of sintered ferrites are established.

In this work, the effect of molybdenum disulfidenanoparticles on the properties zinc oxideelectron transport layer of organic solar cells is studied. molybdenum disulfidenanoparticles were obtained by laser ablation of MoS2 powder in isopropyl alcohol. To form composite films, nanoparticles were added to a sol–gel zinc oxidesolution with different concentrations.According to scanning electron microscope study, as the concentration of nanoparticles in the film increases, the thickness of the molybdenum disulfidelayer on the zinc oxide surface changes. molybdenum disulfidenanoparticles in the film structure gradually fill the bulk and surface voids inzinc oxide. However, when the concentration exceeds 1%, holes and voids are formed in the film. The absorption spectra of composite films showed that as the concentration of nanoparticles in the film increases, the absorption intensity enhances due to theincrease of the overall thickness. At the same time, zinc oxideoptical band gap width doesnot change, which means the molybdenum disulfidenanoparticles do not affect the electronic structure of zinc oxide. It was shown that the observed changes in the volt-ampere characteristicof organic solar cells with composite films electron transport layer composite films was associated with the influence of molybdenum disulfidenanoparticles on electron transport in organic solar cells.According to impedance spectroscopy study, it was found that molybdenum disulfidenanoparticles at concentration below critical value increases the lifetime of charge carriers and the diffusion coefficient in composite film.

Published: April 2023

In this work, the regularities of the change in the shear strength of the adhesive bond τ0and the piezoelectric coefficient β in the metal systems "12Kh2N4 (45KhN2MFA) -steel 45 + B", "12Kh2N4 (45KhN2MFA) -steel 45 + VS" were obtained during physical modeling of the shear of surfaces of small-sized samples and changes in dynamic viscosity environment of their interaction with the use of additional equipment of the SMTs-2 friction machine. It has been established that boridingand boron carburizing of the surface of steel 45 leads to the absence of adhesion to the surfaces of steels 12Kh2N4 and 45KhN2MFA in certain ranges of normal pressures, at which τ0> 0 and the dynamic viscosity of liquid and grease. It was found that the parameter τ0when lubricating surfaces is determined to a greater extent for the system "12X2H4 -steel 45", and partially for borating steel 45 and low values of dynamic viscosity μ = 0.027 Pa•s. With an increase in the dynamic viscosity of the liquid phase of the lubricant in the "12X2H4 -steel 45" system, there is a tendency to an increase inthe value of τ0. It was found that the absence of modification of steel 45 with boron and boron carbide predetermines the independence of the piezoelectric coefficient from the viscosity of the liquid lubricant and the shear rate. Вoridingand boron carburizing steel 45 predetermines an increase in the piezoelectric coefficient by an average of 1.6 times with an increase in dynamic viscosity from 0.027 Pa•s to 0.19 Pa•s at a shear rate of 10.16±0.8. At shear rate = 5.08±0.6 mm/s, the piezoelectric coefficient is relatively constant in the systems under study. With the transition to contact through a grease lubricant, there is an ambiguous manifestation of the rate of change of the piezoelectric coefficient

Solar cell shading or the failure of several photocells changes the output current-voltage characteristic. This paper discusses an algorithm for approaching and searching the maximum power generated on board the spacecraft, which is all-important for fast charging of the secondary sources of electrical energy since the time spent on the sunny side in low orbits are limited by time. Currently, algorithms for finding maximum power work in idealcases, and simple and effective algorithms are needed in cases of solar panel shading or failure of photocell/cells. In this paper, a simulation of a solar panel in various conditions is carried out. An algorithm for constructing the output volt ampere characteristics of a solar cell and a solar panel is implemented. Experiments of various algorithms on real devices have also been carried out.
Anisotropic thermal conductivity in two-dimensional van der Waals crystals
Authors: Jang Mingyu , Singh Swati , Suh Joonki
Published: April 2023

Understanding thermal energy transport of crystalline materials, often highly dependent on their crystalline directions, is crucial for energy harvesting and thermal management applications. In this sense, anisotropy in thermal conductivity (κ), which is the unique characteristic of two-dimensional (2D) materials involving graphene and transition metal dichalcogenides (TMDs), has been attracting tremendous attention in terms of fundamental science and application-driven technology aspects. This distinctive heat transport behavior of 2D van der Waals (vdW) materials generally originates from their intrinsic crystal structures and associated lattice vibrations. Here, we thoroughly review and summarize the anisotropic thermal conductivity in 2D vdW crystals in two different categories: 1) in-plane vs. out-of-plane and 2) between two different in-plane directions. In addition, we introduce a range of thermal conductivity measurement techniques that can be employed for 2D vdW materials provided with their working principles, advantages, and limitations. Beyond their intrinsic anisotropic ratio, we conclude with perspectives on the extrinsic modulations of thermal conductivities, thereby maximizing it toward effective thermal management.
