Published: July 2021

In determining scholarship recipients in schools manually, errors often occur causing inefficient management of scholarship data in terms of time and the absence of clear criteria for how students can obtain scholarships. To anticipate that mistakes do not occur, a Decision Support System is needed. One method that can be used is the Simple Additive Weighting (SAW) method. The data collection method used was the observation method to the school and the interview method with the related teachers regarding the scholarship acceptance. In this research, system development is carried out using the Waterfall method. And for system testing used Black-box Testing. The system design uses the Unified Model Language (UML), which includes usecase diagrams, activity diagrams, sequence diagrams and class diagrams. Then the program implementation uses the PHP programming language and MySQL database. This application will also display the value, criteria, alternatives and then a ranking of the scholarship recipient determination process. With this decision support system, the school will get the results of who is entitled to receive the scholarship. Keywords: Decision Support System, Scholarship, Simple Additive Weighting (SAW) Method, Unified Model Language (UML).
Pergeseran Konteks Syair Arab pada Masa Jahiliyah Hingga Masa Awal Islam
Authors: Syaifuji Achmad , Irawan Bambang 
Published: July 2021

Pada zaman Jahiliyah, kemampuan membuat syair merupakan salah satu parameter intelektualitas seseorang kala itu. Banyak penyair-penyair handal kala itu, salah satunya disebabkan adanya pergelaran atau festival syair dan puisi Arab yang dilaksanakan di pasar-pasar. Tidak sedikit, sering terjadi konflik yang dipicu karena dendangan syair-syair yang saling menghantam antar suku, merayu para wanita serta perihal negatif lainnya yang salah satunya disebabkan karena orang-orang Jahiliyah tidak mempunyai kitab suci, tidak ada Nabi, dan tidak punya sumber hukum. Saat islam masuk, syair-syair yang bernilai negatif, diganti bahkan dibuang yang disesuaikan dengan nilai-nilai religiositas islam dan sebagai media untuk berdakwah. Hal ini menjadi pertimbangan penulis karena syair merupakan bagian dari kekayaan intelektual dari bahasa Arab itu sendiri, sehingga perlu diketahui karakteristik syair-syair pada masa pra islam hingga masuknya islam. Metode yang dilakukan dalam penelitian ini adalah metode kualitatif dengan cara analisis deskriptif dan kajian pustaka terhadap bahan-bahan dari jurnal ilmiah dan buku-buku yang membahas tentang syair-syair Arab pada masa Jahiliyah hingga awal masuknya islam
Particle Temperature Measurements by Spectroscopic and Two-Wavelength Streak Imaging
Authors: Craig J.E. , Parker R.A. , Biancaniello F.S. , Ridder S.D. , Mates S.P. 
Published: July 2021

Abstract
A two-wavelength particle imaging pyrometer has been developed to measure temperature, velocity and size of individual particles within a field of view and a depth of field that spans the entire particle stream in most thermal spray devices. The pyrometer provides continuous updates to particle condition profiles, histograms and correlations. The software locates particle streaks, determines the intensity ratio and dimensions of each streak, and calculates the particle temperature, velocity and size. Many forms of advanced materials processing technologies, such as thermal spray, spray-forming and atomization processes, have considerable need of process control sensor technology. These measurements provide the basis for application of the pyrometer to many of these processes. Particle temperature measurements of plasma-sprayed ceramic powder were obtained using a spectrometer and the pyrometer. Comparisons of the measurements show that the vision-based pyrometer has excellent accuracy. The standard deviation of the measurements was 40 K or about 1.3 %. Additional pyrometer measurements were used to determine its minimum detectable temperature and velocity change, which were 12.4 K and 2.77 m/s, or 0.4 % and 1.5 %, respectively. The vision-based particle sensor can now be applied to high performance control strategies to provide stable particle temperatures and velocities over long duration plasma spray processes.
Modeling of Oxidation of Plasma-Sprayed Molybdenum Coatings

Published: July 2021

Abstract
A model for oxidation of molybdenum particles during plasma spray deposition is developed. The diffusion of metal an-ions or oxygen cat-ions through a thin oxidized film, chemical reactions on the surface, and diffusion of oxidant in gas phase are considered as possible rate-controlling mechanisms with controlling parameters as the temperature of the particle surface, and local oxygen concentration and flow field surrounding the particle. The deposition of molten particle and its rapid solidification and deformation is treated using a Madejski-type model, in which the mechanical energy conservation equation is solved to determine the splat deformation and one-dimensional heat conduction equation with phase change is solved to predict the solidification and temperature evolution. Calculations are performed for a single molybdenum particle sprayed under the Sulzer Metco-9MB spraying conditions. Results show that the mechanism that controls the oxidation of this droplet is the diffusion of metal/oxygen ions through a very thin oxide film. A higher substrate temperature results in a larger rate of oxidation at the splat surface, and hence, a larger oxygen content in the coating layer. Compared to the oxidation of droplet during m-flight, the oxidation during deposition is not weak and can become dominant at high substrate temperatures.

Abstract
Mathematical and computer models of movement and heating of particles in low pressure conditions are developed. The mathematical models are based on the molecular-kinetics theory of gases. A program complex for computer realization of models is developed. It contains a built-in data base of temperature dependent properties of substances, system of processing and graphic visualization of simulation results. For verification of the developed models, computer simulation and experimental measurements of Al2O3 particle temperature and velocity are conducted. These materials were sprayed with Plasma-Technik equipment at pressure 60 mBar in argon. Particle velocity was measured with a special optical device, particle temperature was defined by intensity radiation method. It was established that the developed models are adequate to real process (error of 5-8 %) and may be used for study and improvement of VPS processes.
Properties of WC-Co Components Produced Using the HVOF Thermal Spray Process
Authors: Stokes J. , Looney L. 
Published: July 2021

Abstract
This paper presents a study of the residual stress and microstructural properties of thick, spray-formed components, produced using the High Velocity Oxy-Fuel (HVOF) thermal spraying process. The forming material used is Tungsten carbide cobalt (WC-Co), a material which is more usually processed using expensive press and sinter technology. The aim of this study is to examine the effect of production parameters on the formation of thick components. In order to fabricate thick specimens, certain problems have to be overcome. More specifically these problems include the minimizing residual stresses, which cause shape distortion in the components and maining the integrity of the coating on a microstructural scale. The dependence of residual stress, and sprayed material characteristics on spraying distance, and powder feed rate conditions is presented. Results show that cylindrical WC-Co components up to a thickness of 9mm can successfully be produced, by careful control of these parameters. This represents a significant improvement on maximum thickness values previously reported for WC-Co [1,2].

Published: July 2021

Abstract
Titanium carbide cermet spray powder was produced by the SHS process (Self-propagating High-temperature Synthesis) using elemental Ti, C, Mo and prealloyed CrNiMo powders as starting materials. The powder was characterised (particle size distribution, phase structure, morphology) and the internal structure of each cermet particle was found out to be dense consisting of fine distribution of carbides embedded in a metallic matrix. The particle size range suitable for thermal spraying was obtained by sieving and air classifying. The coatings were prepared by HVOF spraying (DJH2600 and DJH2700). The dry abrasion wear resistance was evaluated by the rubber wheel abrasion wear test and electrochemical corrosion behaviour by open circuit potential measurements. According to the XRD analysis the amount of retained carbides in the coatings is high and the carbide phase has a spherical shape also in the coatings. The microstructure of coatings obtained is dense and the coatings possess good properties in wear and corrosion tests. WC-Co-Cr and Cr3C2-NiCr powders were used for comparison.
Influence of Reaction Enthalpy on the Microstructure of Laser-Alloyed Coatings
Authors: Wilden J. , Frank H. 
Published: July 2021

Abstract
Some applications of thermally sprayed coatings need a metallurgical bonding of substrate and coating. This can be reached by laser remelting of a thermally sprayed coating, which causes, on the other hand, a certain dilution of the substrate elements into the coating. This article discusses the influence of reaction enthalpies on the microstructure formation in the alloying systems Ni-Al and Ti-Al. Experimental work and simulation were done to examine the time constants of solidification influenced by laser dwell time and reaction enthalpy. It was observed that, for short dwell times, the reaction heat dominates the solidification process and the microstructure formation.

Published: July 2021

Abstract
Improved understanding of microstructure-property relationship can help to shift from experiment-based to science-based development of thermally spray deposits. This should result in shorter and less expensive development as well as in higher functionality and reliability of the deposits. Significant amount of work has been done, however, nearly always studying deposits manufactured by only one of the thermal spray techniques. Results are therefore often spray technique specific. A broad study with samples manufactured by a number of different thermal spray techniques seems to be missing yet. Relationships valid across different techniques should provide better understanding of the generic relationships. This research employs number of different techniques - flame, HVOF, plasma (APS, VPS, WSP), to generate a wide range of microstructures. Various Ni-based alloys are studied starting from a simple chemistry (Ni) and ending with complex NiCrAlY alloys. Presented results were obtained with NiCr (80% Ni, 20% Cr) feedstock. Microstructures are characterized by various techniques-OM, SEM, XRD, small-angle neutron scattering (SANS) and others - to obtain the most comprehensive set of macro to micro structural parameters available today. The wear and corrosion properties of these deposits are measured together with internal coating stresses and the most generic microstructure-property relationships are sought.
Hard Arc-Sprayed Coating with Enhanced Erosion and Abrasion Wear Resistance
Authors: Dallaire S. 
Published: July 2021

Abstract
Exposed to particle erosion environments, metal-sprayed coatings are damaged by micro-machining and ploughing at low impact angles. The generation and propagation of subsurface lateral cracks at high impacting angles damage single-phase ceramic coatings. Therefore, multicomponent coatings deposited by high-energy processes have been widely used to provide wear protection in most of the applications. As commercial arc-sprayed coatings have been used to a limited extent in applications involving erosion and abrasion wear, developing attractive wear resistant arc-sprayed coatings has been found necessary. A cored wire formulation, referred to as Alpha-1800, has been developed to produce tailored arc-sprayed coatings that are tough enough to resist particle impacts at 90° and sufficiently hard to deflect eroding particles at low impact angles. Typical 1 mm-thick coatings composed of ductile and hard phases with Knoop hardness reaching 1800 kg/mm2 were easily produced by arc spraying the cored wire with air. Coatings were: 1) erosion tested at 25°C and higher temperatures at impact angles of 25° and 90° in a gas-blast erosion rig, 2) slurry erosion tested at impact angles of 25° and 90°, 3) abrasion wear tested using the ASTM G-65 test procedure. Results show that coatings produced with the new cored wire are at least 5 times more erosion resistant and 10 times more abrasion resistant than coatings produced by arc spraying commercial cored wires. The performance of the new arc-sprayed coating can be compared with that of high-energy WC-based coatings. Being thermally stable up to 850°C, arc-sprayed coatings produced with the new cored wire are attractive for applications in many industrial sectors up to high temperatures.

Published: July 2021

Abstract
The quality and durability of coatings produced by virtually all thermal spray techniques could be improved by increasing the velocity with which coating particles impact the substrate. Additionally, better control of the chemical and thermal environment seen by the particles during flight is crucial to the quality of the coating. A high velocity thermal spray device is under development through a BMDO SBIR project which provides significantly higher impact velocity for accelerated particles than is currently available with existing thermal spray devices. This device utilizes a pulsed plasma as the accelerative medium for powders introduced into the barrel. Recent experiments using a Control-Vision diagnostic system showed that the device can accelerate stainless steel and WC-Co powders to velocities ranging from 1500 to 2200 m/s. These high velocities are accomplished without the use of combustible gases, and without the need of a vacuum chamber, while maintaining an inert atmosphere for the particles during acceleration. The high velocities corresponded well to modeling predictions, and these same models suggest that velocities as high as 3000 m/s or higher are possible.
The Splat Morphology of Plasma Sprayed Particle and the Relation to Coating Property

Published: July 2021

Abstract
Yttria stabilized zirconia particles are plasma sprayed on polished stainless steel substrate. Starting powders are fused and crushed powder, and hollow spherical powder. Four types of the splat morphology, which are splash, rugged, gravel mounted, and disk splats, are observed. Splash and disk splats are fully melted particles, but rugged and gravel mounted like splats are partially melted particles Gravel mounted like splat is observed from only hollow spherical powder, and disk splat is observed in the case of high substrate temperature. It is found that the ratio of splat morphology changes with spraying parameters. Porosity of the coating from fused and crushed powder is higher and Young's modulus of that is lower than that from hollow spherical powder. The ratio of rugged and gravel mounted splats affect porosity and Young's modulus. Adhesive strength increases with the increase in the ratio of disk splat. So, the coating properties are improved by controlling splat morphology. KEYWORDS: Splat Morphology, Partially Melted Particle, Disk Splat, Porosity, Young's Modulus, Adhesive Strength
Micro-and Nano-Scaled Composites via Decomposition of Plasma Sprayed Ceramics
Authors: Colaizzi J. , Kear B.H. , Mayo W.E. , Shropshire R. , Rigney R.W. , Brunhouse S. 
Published: July 2021

Abstract
A method is described wherein a ceramic oxide nanocomposite coating has been produced via a co-precipitation route. The first step in the process consists of forming a solid solution by use of plasma melting, homogenization, and rapid quenching of two ceramics that are normally immiscible. In the best case, the resulting structure is a true solid solution in a new, metastable crystalline structure. The quenched particles can be deposited as a coating or sprayed into water or onto a chill block to form a powder. When the material is sintered via a pressureless process, such as that for a coating, the phase decomposition proceeds quickly, resulting in a homogeneously distributed two-phase structure of micron sized particles. However, when the powders are compacted and sintered at very high pressures (1-8 GPa) and low temperatures (T ~ 0.3 - 0.5 Tm), the increased nucleation of the precipitates results in a composite in which both phases have grain sizes less than 25nm. This paper will review the underlying phenomenon behind the method and the resulting kinetics.
SOFC/CeO2 Doped Electrolyte Deposition Using Suspension Plasma Spraying
Authors: Bonneau M. , Gitzhofer F. , Boulos M. 
Published: July 2021

Abstract
Ceria (CeO2) based electrolytes have been considered for use in solid oxide fuel cells (SOFC) for more than 20 years. There are however some limitations to this usage that this study has tried to address, indeed the study objective has been that of synthesizing and thermal spraying thin layers (50 - 100 µm) of doped CeO2 by the technique of suspension plasma spraying, using radio frequency (RF) plasma technology. Various dopant combinations and concentrations have been selected for this work in order to increase the useful partial oxygen pressure range for satisfactory ionic conductivity development, thereby increasing the anionic conductivity and preventing CeO2 reduction in fuel cell service. Ceria possesses the fluorite crystal structure at low temperatures but does not have enough oxygen vacancies to be a good ionic conductor. In ceria the cerium have 4+ oxidation state within the fluorite structure, and by substituting a certain amount of Ce4+ ions by trivalent dopant ions, oxygen vacancies are induced into the structure. Recent studies have demonstrated that at low temperatures doped ceria seems to be a better electrolyte than doped zirconia. Also, it seems that dopants with ionic radii close to Ce4+ ions give rise to better ionic conductivities. The doped ceria conductivity increases with the dopant concentration because more oxygen vacancies are created, but at higher concentrations vacancy ordering occurs which results in decreased ionic conductivity.

Published: July 2021

Abstract
Thermal spraying of corrosion resistant alloys onto low alloy steel substrates has received much attention as a method to protect against corrosion in seawater or corrosive solutions, such as mineral or organic acids. The need to ensure high coating quality with minimal porosity and cracking, and with low oxide levels is best achieved in metallic alloys using the high velocity oxyfuel (HVOF) spraying process. This article investigates the electrochemical corrosion behavior of HVOF sprayed coatings, covering coating preparation and characterization, immersion testing, and electrochemical testing. The discussion provides information on immersion test results, polarization plots for coatings, comparison of corrosion performance, influence of microstructure on corrosion performance, and comparison with bulk alloy materials. The results reported in this article have been selected to demonstrate the use of the cyclic potentiodynamic polarization method to rank the corrosion performance of HVOF sprayed Ni-alloy coatings.
