Published: December 2022

Abstract
Problems with corrosion resistance in hydraulic cylinders used in marine environments contribute to many failures. Thermal spraying has proven to be a reliable method for replacing electroplated coatings in aircraft, but performance in high corrosive environments is still a drawback. In the present work, a new sealing method to densify WC-CoCr HVOF coatings is tested, which appears to be applicable to hydraulic cylinders in marine environments. The method is based on the use of nanoparticle solutions that penetrate and fill pores and cracks to seal the coatings. Two such solutions are tested and compared to as-sprayed coatings. Open-circuit potential and tribocorrosion measurements in 3.4% NaCl show that sealed coatings are more resistant to corrosion and wear than as-sprayed layers.

Published: December 2022

Abstract
HVOF spraying of fine feedstock powder allows the deposition of cermet coatings with outstanding properties, but selecting and optimizing process parameters can be difficult. In this study, investigators employ a design of experiments (DOE) approach to identify the most relevant process parameters in the spraying of 2-8 μm Cr3C2-NiCr powders. In a screening step, all parameters were assessed in a 12-run Plackett-Burman experimental design and linear models were used to estimate their effect on coating properties and deposition efficiency. The five most influential parameters were then analyzed in a 16-run fractional factorial set of experiments in order to determine their effect, along with all possible two-way interactions, on coating quality.

Published: December 2022

Abstract
This paper describes the basic design and operation of a low-pressure plasma spraying (LPPS) system in use at Sandia National Laboratories. To demonstrate the versatility of the system, Sandia engineers, working in collaboration with the New Mexico Institute of Mining and Technology, produced thin (&lt; 100 μm), dense yttria-stabilized zirconia coatings using three deposition mechanisms: liquid droplet, vapor, and mixed mode (vapor and droplet). Despite slight differences in equipment configuration, the work duplicates many of the results obtained in previous investigations, confirming the advantages of LPPS over other thin film deposition techniques.
Tungsten Thin Films and Nanometer Powder by Low Pressure Plasma Spray
Authors: McKechnie T.N. , O’Dell J.S. 
Published: December 2022

Abstract
A new plasma chemical process has been found that produces tungsten thin films. Using fine powders or precursors as feedstocks, the process vaporizes the feedstocks and then deposits nanometer size grains. The deposition kinetics of structures produced with this technique vary greatly from classical plasma spraying methods. Equiaxed and columnar grains (30-150 nm) are formed instead of splat structures, although the grains may continue to grow after spraying.

Abstract
In order to homogenize the properties of APS sprayed coatings, the spray process was investigated using numerical simulations combined with innovative diagnostic techniques. The process was subdivided into three areas: the plasma torch, the free jet, and coating formation. By simulating these areas separately and combining the results, appropriate process parameters for homogenized coatings were obtained. For a comprehensive computation of coating formation which, besides the impact, flattening, and solidification of particles, includes the mechanical properties of the coating, a volume of fluid algorithm is coupled with a finite element model. In order to verify the modeling of the plasma jet and to provide input data for the coating formation, diagnostic efforts were concentrated on measuring the gas temperature of the plasma as well as particle shape, velocity, and temperature. The results of spatially resolved 3D analysis employing an innovative tomography system are presented and compared with the numerical results.

Authors: Bobzin K. , Schläfer T. , Zhao L. , Kutschmann P. 
Published: December 2022

Abstract
Iron-based wire feedstocks represent a technical as well as economical alternative to carbide reinforced feedstocks for wear protection applications. To assess the potential of such feedstocks, iron-based cored wires were developed with up to 6 wt% boron. The feedstocks were deposited by electric arc spraying, forming hard, partially amorphous coatings with embedded nanocrystalline boride precipitations. To further improve wear resistance, chromium carbide was blended into the powder filling in some wires. Coatings produced from all feedstocks were evaluated by means of optical microscopy, X-ray diffraction, and microhardness measurements.

Chromium content in the powder is in the range of 30 wt% and carbon content is about 5 wt%, yielding a unique powder structure that results in coatings with high and well distributed carbide content. Powder and coating microstructure are examined and the results of wear tests are presented. The extent to which the powders can substitute for conventional carbide coatings is discussed as well.
Comparison of In-Flight Particle Properties, Splat Formation, and Coating Microstructure for Regular and Nano-YSZ Powders
Authors: Elsebaei A. , Heberlein J. , Elshaer M. , Farouk A. 
Published: December 2022

Abstract
This work investigates the effect of atmospheric plasma spraying (APS) parameters on in-flight particle properties, splat morphology, and coating microstructure for conventional and nano-size YSZ powders. Particle temperature and velocity were measured using a dual-slit velocimeter and individual splats and coating microstructures were examined in a scanning electron microscope. The results show that total porosity increases with decreasing arc current and increasing stand-off distance and that conventional powder coatings have higher total porosity at higher arc currents than coatings made from nanopowder. The effect of substrate temperature on splat formation was also assessed. Splat flattening and circularity increase with increasing substrate temperature, particularly for nanopowders.

An Approach to Control the Interlamellar Bonding of Plasma-Sprayed Y2O3-ZrO2 Coatings through Deposition Temperature
Authors: Li C.-J. , Xing Y.-Z. , Li C.-X. , J. Yang G.- 
Published: December 2022

Abstract
Plasma-sprayed ceramic coatings exhibit a lamellar structure with a mean bonding ratio of less than 32%, which dominates coating properties and limits the performance that can be achieved. In this study, yttria-stabilized zirconia (YSZ) coatings were plasma sprayed at different deposition (substrate surface) temperatures up to a maximum of 1100 °C. The lamellar mean bonding ratio, estimated from the ionic conductivity of the YSZ coatings, was found to increase from 32% in room temperature deposits to more than 75% in the deposits prepared at 1100 °C. Evidence of this improvement is also observed in fractured deposit cross-sections. The results show that controlling deposition temperature is an effective way to optimize lamellar interface bonding and, as a result, coating properties.

Published: December 2022

Abstract
The presence of colonial and solitary ciliated peritrichous protozoa was determined in a Sequencing Batch Reactor system filled with tezontle, a volcanic rock, economic, and abundant material that can be found in some parts of the world, like Mexico. The presence of these protozoa was related to the removal efficiencies of organic matter. Also, two novel staining techniques are proposed for staining both colonial and solitary peritrichous protozoa. The results show that tezontle promotes the growth of solitary and colonial ciliated peritrichous protozoa, which, once identified, could be used as indicators of the efficiency of the wastewater treatment process. Additionally, the staining techniques established in the current study allowed the precise observation of protozoan nuclei. They can represent a useful complementary methodology for identifying protozoan species present in water treatment processes, along with the already existing identification techniques. The number and variety of protozoa found in the system may be considered potential bioindicators of water quality during biological treatments.

Published: December 2022

Esse trabalho traz reflexões acerca de uma assunto delicado, pois quando o objeto de estudo é criança e adolescente, é necessário, que seja estabelecido um histórico médico detalhado para a introdução medicamentosa em curto prazo, pois as crianças e adolescentes tendem a reagir mais rápido à medicação que os pacientes adultos. O estudo tem como objetivo apresentar as principais prescrições de medicamentos para o tratamento e suas indicações. O texto é um recorte de uma revisão integrativa da literatura realizada sobre depressão em crianças e adolescentes. Os autores pesquisados afirmam que os medicamentos são capazes de combater a depressão, porém o uso de antidepressivo em crianças e adolescentes tem crescido nos últimos anos, fatores estes que podem ser apontados por pressões externas, contribuindo para que a ansiedade fisiológica progrida cada vez mais para a patológica. No entanto, o uso indiscriminado de medicamentos é capaz de comprometer a saúde emocional e física do paciente e seu bem-estar em geral, principalmente, do paciente infantil, que apresenta resistência imunológica ainda em construção. A prescrição de antidepressivos deve ser cautelosa e pontual, pois exige do profissional que a prescreve conhecimentos sobre os protocolos adequados para a administração medicamentosa, no que diz respeito à dosagem correta do medicamento, a composição química e as reações adversas do mesmo; além da necessidade de saber detalhes sobre o histórico médico do paciente infantil e/ou adolescente. Dessa forma, considera-se que a prescrição dos medicamentos precisam acontecer de modo controlado.
