Published: December 2022

Kualitas atau mutu hasil tangkapan sangat menentukan harga dan peluang bagi pemasaran produk. Pemeliharaan mutu komoditas perikanan di pelabuhan perikanan harus diawali lebih jauh mulai dari atas kapal. Sebagai mata rantai awal bisnis perikanan, nelayan dan tenaga-tenaga bongkar yang ada di pelabuhan perikanan memiliki peran penting dalam menjaga mutu ikan yang dihasilkan. Namun demikian, belum semua nelayan dan tenaga bongkar yang melakukan aktivitas di pelabuhan perikanan memiliki pemahaman tentang pentingnya menjaga mutu ikan dan bagaimana penanganan ikan yang baik. Peningkatan kapasitas nelayan dan tenaga bongkar dalam kegiatan ini dilakukan melalui pemahaman tentang pentingnya menjaga mutu hasil tangkapan mulai dari daerah penangkapan hingga ke pelabuhan dan peningkatan keterampilan cara penanganan ikan yang baik.

Microstructures and Electrochemical Behavior of LSM Cathode with a Structured Electrolyte Modified by Flame Spraying
Authors: Wang X.-M. , Li C.-J. , Li C.-X. , Yang G.-J. 
Published: December 2022

Abstract
Plasma-sprayed yttria-stabilized zirconia (YSZ) can be potentially employed as electrolyte coating in solid oxide fuel cells (SOFCs). The formation of a convex coating surface with semi-melted particles will increase the specific surface area and subsequently improve the output performance of SOFCs. However, using completely molten YSZ particles during plasma spraying leads to the formation of locally flat surface owing to the spreading of the liquid droplets on impact. In this study, flame spraying was employed to deposit YSZ particles on YSZ substrate using surface-melted particles. 4.5 mol% YSZ powder particles were used as spray materials. The deposition was carried out at different spray distances on the YSZ substrate preheated to 650 °C. The surface morphology of YSZ particles was characterized by SEM. The bonding of YSZ particles with the underlying YSZ substrate was examined from cross section. The electrochemical behavior of a single cell with a structured cathode was analyzed by electrochemical impedance spectroscopy. The results show that spray distance has significant influence on the morphology of deposited YSZ particles. The cathode polarization of a structured cathode was decreased by about 30% compared to a flat cathode.

Published: December 2022

Abstract
The aim of this work is to measure the optical reflective properties of plasma sprayed ceramic coatings on glass substrates. The coatings are made with Al2O3-TiO2 powders and are assessed by scanning them with an optical computer mouse. It is shown that mouse movements are smoother on ceramic surfaces than on a standard test pad and tracking performance is more stable, indicating that the reflective properties of ceramic-coated glass are better than those of a typical mouse pad. The ceramic coatings are also shown to have the potential to improve resolution in image recording devices.

Published: December 2022

Abstract
In this investigation, two complex perovskite powders, Ba(MgTa)O and Ta(AlMgT)O, are deposited by atmospheric plasma spraying and evaluated for use as thermal barrier layers. Process parameters are optimized to provide sufficient melting without causing the formation of secondary phases. Deposited coatings are assessed based on composition, morphology, porosity, and thermal cycling lifetime. It is shown that the nature of the starting powders has a significant effect on the lifetime and performance of perovskite-based thermal barrier coatings.

Published: December 2022

Abstract
This study investigates the influence of powder morphology and spray processes on the microstructure, crystallinity, hardness, and elastic modulus of mullite coatings. Coatings produced from mullite powders and suspensions are deposited by plasma spraying while measuring in-flight particle temperature and velocity. Powder morphology and spraying conditions are correlated with measured coating properties, creating a process map for engineering mullite coatings for specific applications. It is shown that coating crystallinity, microstructure, and mechanical properties vary widely depending on powder morphology, processing, and in-flight particle characteristics.
Plasma Spraying of Lanthanum Silicate Electrolytes for Intermediate Temperature Solid Oxide Fuel Cells (ITSOFCs)
Authors: Dru S. , Meillot E. , Wittmann-Teneze K. , Saboungi M.-L. , Benoit R. 
Published: December 2022

Abstract
This study investigates the feasibility of manufacturing lanthanum silicate coatings for solid oxide fuel cells by atmospheric plasma spraying. The coatings produced are cohesive, relatively dense, and contain no secondary phases. Test results show that the starting composition of the powder is maintained after spraying and that particle velocity depends primarily on the plasma gas mixture. Due to the relatively high melting temperature of the particles, dense apatite coatings with few microstructural defects are obtained.
Gastight Yttria-Partially Stabilized Zirconia Layers Manufactured by Suspension Plasma Spraying for SOFC Electrolyte Functional Layers
Authors: Brousse E. , Montavon G. , Denoirjean A. , Fauchais P. , Wittmann-Teneze K. 
Published: December 2022

Abstract
Intermediate temperature solid oxide fuel cells include in their design a solid electrolyte layer, usually made of yttria-stabilized zirconia, that acts as an ionic conductor through which oxygen ions diffuse. This layer must be as thin as possible to limit ohmic losses yet have a low leakage rate corresponding to a low level of connected stacking defects such as microcracks. Suspension plasma spraying (SPS) appears to be a viable method for manufacturing such layers and is used in this study to produce gastight coatings that with further improvements may meet the requirements of SOFCs. The paper describes the setup and optimization of the SPS process and the methods used to evaluate the solid electrolyte layers.
Plasma Sprayed Metal Supported SOFCs Having Enhanced Performance and Durability
Authors: Ansar A. , Ilhan Z. , Arnold J. 
Published: December 2022

Abstract
This paper describes recent improvements in metal supported solid oxide fuel cells produced by plasma spraying. By optimizing the process, incorporating nano-micro structured electrodes, and introducing additional layers to prevent interlayer diffusion, the power density of these cells has doubled, voltage has increased to 1.1 V, degradation rates have been cut in half, and redox stability has improved. Although upscaling to larger substrates initially caused distortion in the metal supports, the problems were successfully overcome.

Published: December 2022

Abstract
In this investigation, titanium dioxide and hydroxyapatite (HA) suspensions are plasma sprayed onto stainless steel, titanium, and aluminum substrates and the structure and properties of the resulting layers are correlated with spraying conditions. The suspensions were formulated with fine TiO2 pigment and HA milled from spray-dried powder or synthesized from calcium nitrate and ammonium phosphate. In some experiments, an atomizer was used to inject the suspensions into the plasma jet, and in others, the suspensions were fed into the jet using continuous stream injection. The deposits are characterized on the basis of morphology, chemical and phase composition, scratch hardness, and dielectric strength.
Suspension Plasma Spraying: Process Development and Applications
Authors: Vaßen R. , Kaßner H. , Mauer G. , Stöver D. 
Published: December 2022

Abstract
Suspension plasma spraying (SPS) offers the manufacture of unique microstructures which are not possible with conventional powder feedstocks. Due to the considerably smaller size of the droplets and also the further fragmentation of these in the plasma jet, the attainable microstructural features like splat and pore sizes can be downsized to the nanometer range. Our present understanding of the SPS deposition process including injection, suspension plasma plume interaction, and deposition is outlined in this report. The conclusions drawn are based on microstructure analysis in combination with enthalpy probe and particle temperature and velocity and measurements. Measurements with a water-cooled stagnation probe provide valuable information on the interaction of the carrier fluid with the plasma plume. The examples presented include segmented thermal barrier coatings for turbine components, LSM cathode deposits for SOFCs, and TiO2 layers for photovoltaic Gratzel cells.
Deposition Behavior of Copper Particles onto Flat Substrate Surface in Cold Spraying
Authors: Fukumoto M. , Mashiko M. , Yamada M. , Yamaguchi E. 
Published: December 2022

Abstract
This study investigates the deposition behavior of cold sprayed copper particles on flat surfaces. In the experiments, a Laval-barrel nozzle was used to spray water atomized spherical copper particles with a mean diameter of 5 µm onto mirror-polished stainless steel. The particles were similar in morphology regardless of spraying conditions with an average bonding strength of 60 MPa as determined by nano scratch (shear) testing. An amorphous-like layer at the particle-substrate interface indicates that the deformation of the particles initially destroys their surface oxide, revealing an active fresh surface that facilitates metallic bonding. At higher spray velocities, metal jetting is observed at the periphery of flattened particles and its relationship with deposition efficiency is statistically analyzed and put forth as a potential method for controlling the cold spray process.
Effects of Gas Pressure of Cold Spray on the Formation of Al Based Intermetallic Compound
Authors: Lee H. , Shin H. , Ko K. 
Published: December 2022

Abstract
Post-annealing of cold spray coatings has great potential for wear applications because it produces intermetallic compounds at low temperature far below equilibrium. This study investigates the effects of spraying pressure on the intermetallics formed and their dispersion characteristics. In the experiments, Al and Al-Ni powders were sprayed on Ni and Al substrates at 0.7, 1.5, and 2.5 MPa and a portion of the coating samples were annealed in argon at 500, 550, and 600 °C. Detailed examinations showed that Al particles are subject to peening effects that can interfere with the formation of intermetallic compounds during annealing, but that the effects can be mitigated by controlling gas pressure. Spraying pressure was also found to have an effect on the formation of eutectic pores in Al-Ni composite coatings, with higher pressures corresponding to fewer pores.

Published: December 2022

Abstract
This study is part of an ongoing effort to develop high performance CoNiCrAlY bond coats by means of cold gas dynamic spraying in order to have complete control of bond coat microstructure. As such, the objective of the work presented in this paper is to perform a detailed analysis of cold sprayed CoNiCrAlY layers to assess any changes in microstructure, relative to the original feedstock powder, that may have occurred during layer build-up and compaction. Based on SEM, TEM, and XRD examination results, it is shown that, contrary to the generally accepted theory, important microstructural changes occur during the cold spray deposition process. In the coating samples examined, investigators observed evidence of grain refinement in the CoNiCr γ-phase matrix and partial dissolution of NiAl β-phase precipitates. These changes are a result of severe plastic deformation due to the high-velocity impact of sprayed particles.
Influence of Spray Materials and their Surface Oxidation on the Critical Velocity in Cold Spraying
Authors: Li C.-J. , Wang H.-T. , Zhang Q. , Yang G.-J. , Li W.-Y. , Liao H.L. 
Published: December 2022

Abstract
Critical velocity is an important parameter in cold spraying. It determines the deposition efficiency under a given spray condition. It depends not only on material types, but also particle temperature and oxidation conditions. In this present work, three types of materials including copper, 316L stainless steel, and Monel alloy were used to deposit coatings by cold spraying. The critical velocities of spray materials were determined using a novel measurement method. Oxygen content in three powders was changed by isothermal oxidation at ambient atmosphere. The effect of oxygen content on the critical velocity was examined. It was found that critical velocity was significantly influenced by particle oxidation besides material properties. The critical velocity of Cu particles increased from about 300 m/s to over 610 m/s with a change in oxygen content in the powder. The results suggest that with a severely oxidized powder, critical velocity tends to be dominated by the oxide on the powder rather than material properties.
Nano Titania Embedded Hydroxyapatite Coating by Precursor Plasma
Authors: Varadaraajan V. , Visveswaran R. , Mohanty P.S. 
Published: December 2022

Abstract
In recent studies, titania has been added to hydroxyapatite (HA) coatings to impart photocatalytic properties. The benefits of such additions are maximized when titania is in nanocrystalline anatase form. In this study, nano-titania was synthesized in-flight from a liquid precursor consisting of ethanol and titanium isopropoxide. The precursor and HA powder were fed into a plasma gun, forming nano-titania particles that embedded in the HA. Coatings of pure titania and titania-embedded HA were deposited under different spray conditions on titanium coupons and then characterized via XRD and SEM analysis. The titania coatings contained ultrafine anatase and rutile particles with anatase being favored by more power input and rapid quenching. The composite coatings contained dispersed ultrafine titania particles in a matrix consisting primarily of HA with trace amounts of calcium phosphate and amorphous phases. The effect of spraying parameters on phase and microstructure evolution is discussed as well.

Published: December 2022

Abstract
This study assesses the photocatalytic properties of HVOF-sprayed nanostructured TiO2 coatings, particularly their bactericidal effect. The surfaces of the coatings were lightly polished before being exposed to bacterial solutions of known concentration. The solution was dispensed on the coating and irradiated with white light in 30-minute intervals up to 120 minutes. On polished HVOF-sprayed TiO2 coatings, 24% of the bacteria were killed after 120 minutes of exposure. On stainless steel controls, the percentage of bacterial cells killed was approximately 6% for most of the exposure times studied.

Published: December 2022

Abstract
Recently, an advanced technique was developed to fabricate sandwich structures for high temperature applications by depositing alloy 625 skins on Ni alloy foam core by thermal spraying. This study tries to utilize an analytical model to estimate the mechanical performance of these structures based on the mechanical properties of the constituents. The mechanical behavior of the Ni alloy foam is assessed via compression testing, while tensile tests are used in the case of the alloy coating. The flexural rigidity of the sandwich structure is calculated using analytical models and experimentally obtained elastic moduli of the alloy 625 coating and Ni alloy foam. The model is also used to calculate the flexural rigidity of sandwich samples with different skin thicknesses to check the accuracy of the model and to understand the effect of skin thickness on the predicted mechanical performance of sandwich structures. The effect of heat treatment on the mechanical behavior of sandwich structures is investigated as well.
