A Clash of Symbols: When I Put on What I Want to Put on
Authors: Forsyth Louise H. 
Published: June 2023

Et puis tous les moyens sont bons pour me rejoindre. Et si je n’viens pas à moi, c’est moi qui irai à moi.2 - Marie Savard, Bien à moi 43 Le monologue était une caractéristique du théâtre de femmes à ses débuts. Quoique les gens moins gentils ne disaient même pas « monologue » , ils disaient « témoignage ». « Le théâtre de femmes, ce n’est pas de l’art, c’est du témoignage : un paquet de femmes qui racontent leur vie. » 1 - Pol Pelletier, Joie 22 Marie Savard’s Bien à moi was created with Michel Tremblay’s La Duchesse de Langeais at the Théâtre de Quat’Sous in Montreal in February 1970. The almost universal reaction to Savard’s extraordinary monologue was that the character was deranged, incoherent and uninteresting. Savard later said, “C’était une féministe qui s’ignorait et heureusement d’ailleurs. Elle se serait sentie bien trop seule à cette époque” (11).4

Body weight correction of adolescent girls by health fitness tools
Authors: Zhdanova Olga , Chekhovska Liubov , Luzhna Maryana , Stefanyshyn Markiian 
Published: June 2023

The health condition of teenagers tends to deteriorate. In Ukraine, 30-40% of the population suffers from obesity, of which 15-17% are children and adolescents. In order to solve the mentioned problems, innovative modern fitness programs should be implemented, which would meet the needs of teenagers, contribute to increasing the level of their motor activity, improve general well-being, and save time. EMS training is one of these. In pediatrics, electrical stimulation is used for obesity. The modern vision of the use of electromyostimulation is a type of rehabilitation fitness, "fitness of the future".
The purpose of the study was to correct the body weight of adolescent girls under the influence of EMS training. The study was conducted in the fitness club "JUSTFIT" with girls 15-16 years old (n=15) twice a week for 30 minutes. The pedagogical experiment has been lasted for 6 months. During the training, a special wireless EMS suit was used with pads on the hips and chest to which the electrodes were connected. Low-frequency electrical impulses were applied to them, which caused muscle contraction during exercise. EMS training included a warm-up (on the orbiterk), the main part (circular training in a moderate mode: cardio and strength training) and the hang up (relaxation - lymphatic drainage massage). The trainer individually selected the load, strength of impulses and formed the training process. EMS training gives quick results, thanks to the simultaneous training of all muscle groups during physical exercises.
A statistically significant difference was established between the average values of all anthropometric indicators of girls 15-16 years old at the beginning and at the end of the pedagogical experiment (р<0.05). Therefore, EMS training is considered a popular and effective fitness program.

Authors: Valarezo A. , Dwivedi G. , Sampath S. , Musalek R. , Matejicek J. 
Published: June 2023

Abstract
This study investigates the effect of high deposition rates and temperatures on the formation of vertical segmentation cracks in thermal barrier coatings. YSZ layers were deposited by atmospheric plasma spraying using different powder feed rates, raster speeds, and spraying distances. Coating cross-sections were examined, elastic properties were measured, and thermal conductivity was determined by laser flash testing. Coating structures with vertical and horizontal cracks are shown to be anelastic with high strain tolerance, even after heat treating at 1100 °C.
Characterization of a HVOF-Sprayed WC-CoCr Coating Before and After Laser-Assisted Turning
Authors: Bobzin K. , Zhao L. , Öte M. , Linke T. F. , Klocke F. , Brummer C. , Graefe S. 
Published: June 2023

Abstract
This study evaluates a new surface finishing process called laser-assisted turning. WC-CoCr coatings were produced by HVOF spraying and characterized based on surface morphology, microstructure, and friction and wear properties. The coatings were then treated using the new process and re-examined and tested. Surface roughness and hardness were significantly improved, although friction and wear properties were found to be inferior to those of WC-CoCr coatings finished by grinding and polishing.
Influence of Process Parameters and Feedstock Selection on Coating Microstructures with a Cascaded Plasma Torch
Authors: Chen D. , Dambra C. , Sabouni O. 
Published: June 2023

Abstract
Three YSZ powders with different particle size distributions and an ethanol-based YSZ suspension were deposited on steel substrates using a cascaded plasma torch with a 9 mm nozzle. Coatings with dense, porous, segmented, and columnar microstructures were achieved by varying process parameters such as gun current, argon flow rate, spray distance, and suspension injection pressure. Linear relationships between in-flight particle state and process variables were observed and are shown to correlate well with coating structure and porosity.
Thermal Sprayed Y2O3-Al2O3-SiO2 (YAS) Coatings for Environmental Protection of SiC Ceramics
Authors: García E. , Nistal A. , Sainz M. A. , Osendi M. I. , Miranzo P. , Martín de la Escalera F. , Khalifa A. 
Published: June 2023

Abstract
In this work, a low-temperature melting composition located within the glass-forming region of the Y2O3-Al2O3-SiO2 (YAS) system is proposed and tested as a protective coating for SiC ceramics. Glassy coatings 197 µm thick were obtained by flame spraying YAS granules on SiC substrates that had been grit blasted and coated with a Si bond layer. Bulk glasses of the same composition were also produced for use as a reference material. The hardness, elastic modulus, and thermal conductivity of the coatings and bulk specimens were evaluated and compared and the effect of heat treatment was investigated. Crystallization occurred in both the bulk glass and coating during isothermal treatments in air at 1100-1350 °C, but it did not compromise system integrity due to crack healing.

Influence of the Powder Morphology and Plasma Spray Process Parameters on the Structure and Properties of Al2O3 Based Plasma Sprayed Coatings
Authors: Matikainen V. , Koivuluoto H. , Vuoristo P. , Larjo J. 
Published: June 2023

Abstract
In this investigation, alumina powders prepared by different methods were sprayed on carbon steel substrates using a conventional plasma torch with radial injection. The spraying process and powder injection parameters were varied and the injection behavior of the powder was studied. Changes in particle acceleration, deceleration, and impact were measured with novel spray diagnostic equipment and are correlated with the structure and properties of the coatings obtained. Dense coatings were achieved with several agglomerated-and-sintered Al2O3 powders, although higher impact velocities and temperatures were recorded for the larger and denser fused-and-crushed particles.

Authors: List A. , Gärtner F. , Assadi H. , Klassen T. , Mori T. , Kuroda S. 
Published: June 2023

Abstract
In this investigation, cold spraying is used to deposit a simple binary amorphous alloy with technical purity. Cu50Zr50 was chosen as the model system due to its glass-forming ability and insensitivity to changes in composition. Critical velocities for coating formation were experimentally determined by systematic variation of spray parameter sets. These values were then used to tune existing bonding models to cold spraying of amorphous Cu50Zr50 powder. It is shown that under suitable conditions, well adhering coatings with the amorphous structure of the powder can be obtained by cold spraying with nitrogen as the process gas.

Authors: Li R. , He D. , Zhou Z. , Wang G. , Jiang J. 
Published: June 2023

Abstract
In this study, Fe-Cr-Al and Fe-Cr-Al-B cored wires were produced and deposited on steel substrates by wire arc spraying. The microstructure, hardness, and high-temperature corrosion behavior of the cored-wire deposits were evaluated in comparison to Fe-Cr and commercial Fe-Cr-Al solid-wire coatings. All coating samples exhibited lamellar microstructures with oxide inclusions, the fewest being in the Fe-Cr-Al-B deposits. Microhardness was measured along coating cross-sections at various distances from the coating-substrate interface. The Fe-Cr coatings were the hardest, followed by the Fe-Cr-Al-B deposits. Thermogravimetric analysis was used to evaluate high-temperature corrosion behavior in a molten salt environment under cyclic conditions, with the Fe-Cr-Al-B cored-wire deposits performing the best.
Plasma Sprayed Y2O3 Coating on C-FRP with Aim of Development of Future Mold Materials for Integrated Circuit Encapsulation
Authors: Ganesan A. , Yamada M. , Fukumoto M. , Kitaoka S. 
Published: June 2023

Abstract
The aim of this study is to improve the releasability of carbon fiber reinforced plastic (C-FRP) molds by depositing a plasma-sprayed Y2O3 coating on working surfaces. Composite molds are considered for use in IC encapsulation. To promote adhesion, an interlayer, either copper or gradient yttria, is applied between the substrate and coating. The coatings deposited over gradient Y2O3 performed better than coatings applied over copper due to the large reduction in thermal mismatch achieved with a graded thermal expansion coefficient. Preliminary releasability results show that the yttria coatings have high adhesion strength and the potential to uniformly reduce release forces between C-FRP surfaces and epoxy resins.
Insulating Coatings for High-Performance Electronic Components Produced by Thermal Spraying Considering Electrical and Mechanical Characteristics
Authors: Cichosz M. , Trenkle F. , Hartmann S. , Wilde J. 
Published: June 2023

Abstract
This work investigates the properties of insulating coatings deposited by HVOF and atmospheric plasma spraying and the effects of various sealants. It is shown that adhesive tensile strength depends strongly on surface roughness and that the dielectric strength of a material is normally higher in the unsealed state. In the case of a new sealant, however, the dielectric strength of HVOF sprayed alumina coatings is shown to be higher in the sealed state, which potentially opens new applications in high-performance electronics.
Lanthanum and Gadolinium Zirconate Thermal Barrier Coatings Structure and Properties Evolution
Authors: Mazilin I. , Baldaev L. , Drobot D. 
Published: June 2023

Abstract
In this study, lanthanum (LZ) and gadolinium zirconate (GZ) powders were prepared by spray drying and deposited on graphite substrates by air plasma spraying. Free-standing 1-1.5 mm thick LZ and GZ coating samples were obtained by mechanical delamination and subjected to long-term annealing in air at 1250 °C. Significant changes occurred during heat treating in the form of microstructure evolution, crystal structure ordering, and phase transitions as observed via SEM, XRF, and XRD analysis. These changes affected a number of coating properties, including hardness, porosity, fracture toughness, and thermal conductivity. In the first 20 h, thermal conductivity increased in gadolinium zirconate from 0.5 to 1.0 W/m·K and in lanthanum zirconate from 0.5 to 1.5 W/m·K.
Design of Experiment Oriented Fluid Simulation for the Virtual Improvement of the Air-Cap Configuration in Twin-Wire Arc-Spraying (TWAS) Process
Authors: Tillmann W. , Abdulgader M. , Anjami N. , Hagen L. 
Published: June 2023

Abstract
In this work, CFD simulations are used to evaluate air cap configurations for twin wire arc spraying (TWAS). Investigators employed a design of experiments (DoE) approach to identify air cap parameters with the greatest impact on gas velocity, jet convergence, and pressure distribution. The ones selected for study are the convergence angle, the length and diameter of the throat, and the distance between the air cap outlet and the point where the wires intersect. In all configurations studied, the spray wires deflected the flow of the primary gas and narrowed the cross-section of the plume along one axis. The effects of each air cap parameter are discussed in the paper along with possible design improvements.

Authors: Berger L.-M. , Shakhverdova I. , Puschmann R. , Gräfensteiner M. , Leidich E. , Schiefer S. , Gerlach M. 
Published: June 2023

Abstract
This paper presents the results of a study on the static friction properties of (Ti,Mo)(C,N)-Ni hardmetal coatings deposited by HVOF spraying. Coating samples were sprayed on quenched and tempered CrMo steel friction rings using an experimental feedstock powder. Friction surfaces were characterized based on the geometry and distribution of prominent peaks and static coefficient of friction was measured. Test results show that the hardmetal coatings have good potential for use in frictionally engaged joints, but more work is needed to establish a correlation between coating properties and friction behavior.

Thermal Sprayed Protective Coatings for Superplastic Forming Ceramic Dies: A Monitoring System of Die Condition
Authors: Staiano A. , Ion W. , O’Hare L. 
Published: June 2023

Abstract
Superplastic forming (SPF) is an advanced sheet manufacturing process typically used for low- volume, high-value products. SPF dies made from refractory castables have a lower production cost than metal dies, but their brittle nature is a limiting factor. This work investigates surface degradation mechanisms in ceramic dies and how they are affected by the application of thermal spray coatings. Among the more notable accomplishments of the study is the development of a test rig that simulates die-part interface conditions during superplastic forming and monitors die wear, making it possible to predict ceramic die lifetime for different coatings.
Interface Characterization and Bonding Mechanisms of Cold Gas Sprayed Al Coatings on Ceramic Substrates
Authors: Drehmann R. , Grund T. , Lampke T. , Wielage B. , Manygoats K. , Schucknecht T. , Rafaja D. 
Published: June 2023

Abstract
This work investigates the adhesion mechanisms associated with cold gas sprayed metallic coatings on ceramic substrates. Aluminum layers were deposited on sintered corundum plates and single-crystalline sapphire substrates with different lattice orientations. Examination of the interface region showed that adhesion was the result of recrystallisation and heteroepitaxial growth. Cold spray aluminum coatings were also deposited on Al2O3, AlN, Si3N4, and SiC substrates to determine if ionic bonding plays a role in interface formation. For comparison, aluminum coatings produced by physical vapor deposition were also examined.

Authors: Salavati S. , Pershin L. , Coyle T. W. , Mostaghimi J. 
Published: June 2023

Abstract
In this study, porous and dense layers of alloy 625 are deposited on nickel foam sheets using a modified twin wire arc spraying process. Sandwich panels with arc-sprayed alloy 625 skins on nickel foam cores were fabricated then subjected to four-point bend testing. The effects of skin porosity on flexural rigidity and overall mechanical behavior are investigated. The ductility of porous alloy 625 skins was improved after heat treatment at 1100 °C for 3 h.
3D μCT and SEM Analysis of Resolidified Tips of Cored Wires Used in Twin Wire Arc Spraying
Authors: Nellesen J. , Abdulgader M. , Tillmann W. , Beckmann F. 
Published: June 2023

Abstract
The homogeneity of thermal spray plumes is mostly dependent on the type of feedstock used. Powdery feedstocks, for example, promote homogeneity. If in-flight particles are atomized from a melting bath, however, as in twin wire arc spraying (TWAS), the spray jet is less homogeneous due to the fact that particles are generated by the impingement of an airflow on the melting tips of electrically conducting wires. This work aims to contribute to the understanding of the initiation of such particles in the TWAS process. To that end, cored wires filled with W-rich particles were sprayed, then the process was halted and the wire tips were examined to analyze how the filling powder interacts with the melted part of the velum. 3D tomograms show that the resolidified melt bath is interspersed with spherical and irregular-shaped W-rich particles. The irregular shape implies a partial melting of the W-rich particles.
Study of the Residual Stress Distribution of Thermally-Sprayed TBCs Involving Various Interfaces and Laser Drilling
Authors: Guinard C. , Guipont V. , Jeandin M. , Montay G. 
Published: June 2023

Abstract
The aim of this study is to measure residual stress profiles in conventional and continuously graded thermal barrier coatings (TBCs), including those with laser-drilled effusion holes added to improve heat protection. Three sets of TBCs with different bond coat-topcoat interfaces were produced on Haynes 188 substrates. Two sample sets were prepared by plasma spraying NiCrAlY and YSZ powders, in one case, at fixed feedrates, and in the other, at feedrates simultaneously changing in opposite directions. A third sample set was obtained by combining a cold-sprayed CoNiCrAlY bond coat with a plasma-sprayed YSZ topcoat. Residual stress profiles were measured by means of incremental-step hole drilling and speckle interferometry. An original test method was also developed and is used to determine residual stress gradients before and after effusion hole drilling. The results are presented and discussed along with best practices for controlling residual stresses.

Chemical Reactions of Different Types in Detonation Sprayed Powders as Tools of Coating Design
Authors: Ulianitsky V. Yu. , Batraev I. S. , Dudina D. V. , Bulina N. V. 
Published: June 2023

Abstract
This work shows that with computer-controlled detonation spraying, the phase composition of coatings can be changed relative to that of the feedstock powders. New phases can appear in substantial quantities due to chemical reactions of reduction, oxidation, and nitridation as well as interfacial interactions between phases in composite powders. The key advantage of computer control is that it precisely regulates the quantity and stoichiometry of explosive gas mixtures. It has thereby been found that TiO2 experiences partial reduction to titanium suboxides and that chemical reactions with nitrogen are also possible. It has also been found that when nitrogen is present, titanium aluminides, Ti3Al and TiAl, are likely to form nitrides in the sprayed coatings. Interfacial reactions between the phases of a composite have been studied, and in the case of the Ti3SiC2-Cu system, it has been found that deintercalation of Si can be prevented by maintaining relatively cold spraying conditions. At higher temperatures, coatings of an unusual phase composition form in which carbon-deficient TiCx inclusions are distributed in the Cu matrix as modified by the dissolution of silicon. The formation of new phases affects coating microstructure development and results in new microstructural features.

Effects of Spray Parameters and Heat Treatment on the Microstructure and Mechanical Properties of Titanium Coatings Formed by Warm Spraying
Authors: Molak R. , Kuroda S. , Araki H. , Watanabe M. , Katanoda H. , Ohno N. , Fukanuma H. 
Published: June 2023

Abstract
In this present work, investigators determine how particle temperature, combustion pressure, and heat treatment affect the porosity, oxide content, and tensile properties of warm-sprayed titanium. Coatings were deposited with nitrogen flow rates ranging from 0.5 to 1.5 m3/min and combustion pressures of 1 and 4 MPa. Optimal coating properties were found for specimens formed at a nitrogen flow rate of 0.75 m3/min and a combustion pressure of 4 MPa. Post-spray heat treatment was found to improve bonding between deposited particles, significantly increasing the strength and ductility of the titanium coatings.
Modeling the Gas Flow and Coating Particles in the Hydrogen Fueled HVOF Process
Authors: Pinomaa T. , Suhonen T. , Varis T. 
Published: June 2023

Abstract
In this work, a CFD model is built to investigate gas flow and in-flight particle characteristics in HVOF spraying with hydrogen as the fuel. Gas flow is solved for a particle-free jet, combustion is represented using a simple eddy-dissipation model, and a time-averaged fluid flow (k-ε) model is used to account for turbulence. Acceleration and heating of individual particles are modeled in a "snapshot" of the gas flow. Particle acceleration is shown to be governed by drag and particle heating by conduction and radiation between particulates and gas phases. Modeling results agree well with experimentally obtained data and observations.
