Published: November 2022

<p><em> </em><em>This research aims to measure the disaster literacy of residents in Disaster-prone Area (DPA) III and its support villages in Magelang Regency related to the Sister Village-based disaster mitigation. The four-level disaster literacy model (basic disaster literacy, functional disaster literacy, communicative/interactive literacy, and critical disaster literacy) is used to explain the manifestation of awareness, knowledge and understanding of DPA III villagers and their support villages regarding the Sister Village program. This qualitative research uses a constructivist approach. The data was collected through in depth-interview with research respondents, namely village officials and the Disaster Risk Mitigation Team in Ngargosoko, Nglumut, and Kapuhan villages (located in DPA III) as well as Sucen, Gulon and Mangunsari villages (support villages). The results showed that there are concrete manifestations of awareness, knowledge understanding and behavior of the villagers regarding the Sister Village program at these four levels. However, the context is preparedness or non-disaster and before disaster conditions. For example, the understanding of the table-top exercise and field exercise function held by BPBD Kabupaten Magelang. The function of the Sister Village program is to collect population and pre-existing facilities data on a regular basis, conduct awareness programs in accordance with respondents’ job description in the Sister Village program and map the aspects of disaster mitigation to minimize disaster risks. As for the condition during disaster and after disaster, it is still cannot be seen from the research results because at the time of the research, the respective community was not facing eruption disaster, given that the last Merapi eruption occurred in 2010 and the Sister Village program was only initiated a year later.</em></p>

Published: November 2022

This research is a comparative analysis between two mass media in producing politic news responding to the establishment of the new KPK law by using Critical Discourse Analysis. The research aims to look for and to compare the social wrongs and ideologies brought by the writers from the chosen texts. In order to do critical analysis discourse, the researchers use Fairclough analytic-three-dimensional framework which is wrapped in the four stages of Roy Bhaskar explanatory critiques presented by Fairclough (2013).The first stage focuses on the social wrong which has semiotic aspects that is analyzed through its linguistic choice by using Appraisal theory proposed by Martin and White. The social wrong of the text is represented by the use of attitude consisting of affect, appreciation, and judgment as it shows the writers’ attitude towards the related parties in the texts. The second stage identifies the obstacles to it being tackled through the analysis of the network of practices, the relationship of the semiosis to other elements and the semiosis itself. It is analyzed using Gee’s Seven Building Tasks of Language. It aims to analyze the areas of “reality” that are built through the texts, which can be used to understand the meaning of the discourse. It may also be used to understand different aspects of the meaning being created through discourse. The ideology of the text is represented by the significances, activities, identities, relationships, politics, connections, and sign systems &amp; knowledge in the texts. The third stage considers whether the social order needs the problems/the social wrong. The last stage reveals the possible ways to tackle the obstacles. The findings from these steps of analysis are combined and interpreted together. It is found that the article produced by The Jakarta Post, as a verified news editorial by the Indonesian Press Council, apparently seems to share more negative attitudes compared to Independent Observer which is not verified yet. This shows the social wrong establishes in the social order: the politicization of the media, which is clearly unnecessary in the social order since it makes the media are politically polarized. Despite the ideological differences in the two articles, both articles basically share the same ideology: the importance of eradicating corruption in Indonesia.

Published: November 2022

Abstract
Multi-electrode APS has proven significant advantages with regard to spray rates, deposit efficiency and component life time. So far, three-cathode and three-anode spray guns have been established successfully in several industrial sectors where high spray rates are mandatory. Based on the successful three-anode plasma spray gun DELTA, the five-anode APS gun PENTA was developed to further increase productivity. With its gross power of up to 125 kW it allows very high spray rates and thus significantly reduced coating times. This paper focusses on the development of high spray rate parameter settings for producing oxide ceramic coatings. All coatings will be investigated with regard to their microstructures. Furthermore, economical benefits of the five anode technology will be highlighted.
Practical Aspects of Suspension Plasma Spray for Thermal Barrier Coating on Potential Gas Turbine Components
Authors: Ma X. , Ruggiero P. 
Published: November 2022

Abstract
Suspension plasma spraying (SPS) process has attracted extensive effort and interest as a method to produce fine-structured and functional coatings. In particular, thermal barrier coating (TBC) applied by SPS process has gained increasing interest due to its potential for producing coatings that provide superior thermal protection of gas turbine hot-section components as compared to conventional APS-TBC and even EB-PVD TBC. The unique columnar architecture and nano- and submicron sized grains in a SPS-TBC coatings demonstrate some advantages in thermal shock durability, low thermal conductivity, and high-temperature sintering resistance. This work addresses some practical aspects of using the SPS process for TBC applications before it becomes a reliable industry method. The spray capability and applicability of SPS to achieve uniform thickness and microstructure on curved substrates was evaluated in designed spray trials to simulate industrial parts with complex configurations. The performance of SPS-TBCs in erosion, free falling ballistic impact, and indentation loading tests was evaluated to simulate SPS-TBC performance in turbine service conditions. The behaviors of SPS-TBCs in those tests were correlated to key test factors including grit incident angles, impact object sizes, indentation head shapes, and coating surface curvatures. Finally, a turbine blade was coated and sectioned to verify SPS sprayability in multiple critical sections. The SPS trials and test results demonstrate that SPS is promising for innovative TBCs, but some challenges need to be addressed before it becomes an economical and reliable industrial process, especially for gas turbine components.
Effect of Spray Parameters on the Microstructure and Porosity Content of Gadolinium Zirconate TBCs Deposited by Suspension Plasma Spray

Published: November 2022

Abstract
Gadolinium zirconate (GZ) is considered as a promising top coat candidate for high temperature (&gt;1200 °C) thermal barrier coating (TBC) applications. Suspension plasma spray (SPS) technique has shown the capability to generate a wide range of microstructures which includes the more desirable columnar microstructure. In this study, GZ single layer TBCs were deposited by axial SPS process. The variable parameters include the standoff distance, solid load content of the suspension and input power. The cross section and top surface of the as sprayed TBCs were analyzed by SEM. The phase content in the as sprayed TBCs was analyzed by XRD. The porosity content of the as sprayed TBCs was measured using image analysis. In the SEM analysis, it was observed that a lower solid load content in the suspension favored the formation of a columnar microstructure. Additionally, at lower solid load content, increase in standoff distance resulted in columnar microstructure with high porosity content in the TBC. However, with higher solid content suspension and alteration of input power, only a dense vertical cracked microstructure can be obtained.

Published: November 2022

Abstract
This study was focused on the biocidal efficacy on spores of copper alloy sheet and copper alloy coating at two different surface topographies. Endospores can remain viable in a dormant state for centuries. Our work compares the effectiveness of copper alloy coating and copper sheet metal in killing endospores. A twin-wire arc spray system was used for coating of stainless steel coupons. The feedstock was CuNiZn wire, the coating thickness was 400 µm. The copper alloy sheet metal had the same composition and is registered as antimicrobial by Environmental Protection Agency (US). Uncoated stainless steel coupons were used as controls in all experiments. The surface was polished to two roughness levels: Ra=3.5 µm and Ra=0.1 µm. The surface topography was analyzed by a stylus profilometer and 3D image analysis. EDS and FIB were used to characterize the elemental composition and structure of flower-like nanostructures and endospores. The results obtained in this study indicated that changes in Ra values of 0.1 and 3.5 µm had no significant impact on the biocidal activity of sheet metal and the coating on E. coli, S. epidermidis and B. subtilis. The coating was as effective as the EPA-certified sheet metal in the destruction of vegetative cells within 5 minutes. This study indicates that degradation of B. subtilis endospore begins within 2 hours after exposure to the coating. By day seven, only extensively degraded endospores and nanostructures were visible on both surfaces. Our results show that thermal spray copper alloy coatings were as effective as certified antimicrobial sheet metal in the destruction of endospores within hours; however, the coating was more effective in killing the endospores after one week of exposure.

Published: November 2022

Abstract
In order to guarantee their protective function, thermal sprayings must be free from cracks, which expose the substrate surface to e.g. corrosive media. Cracks in thermal sprayings are usually formed because of tensile residual stresses. Most commonly, the crack occurrence is determined after the thermal spraying process by examination of metallographic cross-sections of the coating. Recent efforts focus on in situ monitoring of crack formation by means of acoustic emission analysis. However, the acoustic signals related to crack propagation can be absorbed by the noise of the thermal spraying process. In this work, a high-frequency impulse measurement technique was applied to separate different acoustic sources by visualizing the characteristic signal of crack formation via quasi-real-time Fourier analysis. The investigations were carried out on a twin wire arc spraying process, utilizing FeCrBSi as a coating material. The impact of the process parameters on the acoustic emission spectrum was studied. Acoustic emission analysis enables to obtain global and integral information on the formed cracks. The coating morphology as well as coating defects were inspected using light microscopy on metallographic cross-sections. Additionally, the resulting crack patterns were imaged in 3D by means of X-ray micro-tomography.

Authors: Liu T. , Ansar A. 
Published: November 2022

Abstract
Dual layer electrode coating for alkaline water electrolysis was prepared by plasma spraying. For improving performance this work aims at reducing the oxide in electrode coating. Regarding the necessity of obtaining high specific area, atmospheric plasma spray was employed under protection of argon which was used as shrouding gas. Composite cathode was established on Ni-coated perforated steel sheet with crushed and gas atomized Nickel-based alloy powders. The dual-layer structure was a composite of 5 layers of NiAl at the bottom and 10 layers of NiAlMo as the top layer. Microstructure and morphology were studied by scanning electron microscope (SEM). Element content was estimated by energy dispersive spectrometer (EDS). Enthalpy probe was introduced for measuring plasma temperature and velocity as well as gas composition. Numerical calculation was carried out with same condition for better understanding the shrouding effect. The results showed moderate protection by using of arranged gas shrouding. Overall, in the dual layer region, oxygen content was decreased by 0.3%, from 3.46% to 3.15%. With gas shrouding coating exhibited similar element contents as coating sprayed by VPS. However, no obvious difference was observed in microstructure and morphology with or without gas shrouding.

Published: November 2022

Abstract
Phase composition and microstructure of hydroxyapatite (HA) significantly affects the biological and mechanical properties of final hydroxyapatite (HA) coating. In the present study, HA coatings were deposited on Ti-6Al-4V by micro-plasma spraying (MPS) using different spray parameters. The influence of spray parameters on the composition and microstructure of the coatings were investigated. To understand the formation mechanism of HA coatings, the in-flight particles and splats were examined as well. The morphologies of coatings surface, cross-sections, initial powder, in-flight particles and splats were characterized by scanning electron microscopy (SEM). Xray diffraction (XRD) was employed to analyze the phase composition. Three typical HA coatings were fabricated. The results indicated that the coating composition and microstructure were tightly related to the melting state of inflight particles. And this was influenced by the spraying parameters. The formation mechanisms of these coatings were discussed.
Effects of Carbon Contents and Gas Type on Hardness and Wear Resistance of Ferrous Coating Fabricated by Twin Wire Arc Spray Process

Published: November 2022

Abstract
In automotive industry, thermal spray process is used to reduce engine weight by replacing cast iron liners inserted in cylinder bores. Especially, twin wire arc spray is one of widely used thermal spray processes with inexpensive cost and high deposition rate. In this study, two kinds of wire materials, low carbon steel (0.07 wt.%C) and high carbon steel (0.80 wt.%C) were deposited by twin wire arc spray process using two kinds of process gas (i.e., compressed air and nitrogen) in order to elucidate effects of carbon contents of ferrous coating and process gas type on the hardness and wear resistance of coating. In case of hardness, low carbon steel coatings had higher hardness when air was used as process gas whereas high carbon steel coatings had higher hardness when nitrogen was used, which was caused by the counter effects of carbon loss and oxide formation. The results of sliding wear test in lubricated condition indicated that coatings with higher hardness have better wear resistance and oxides improve wear resistance by playing a role as solid lubricant. The main wear mechanism was splat delamination induced by inter-splat crack, and traces of other wear behaviours such as splat tip fracture and abrasive wear were also observed.
Effect of Different Shroud Principles on the Performance of a NiTi Coating Produced by Means of Twin-Wire Arc Spraying (TWAS) Process

Abstract
The super-elasticity behavior of a NiTi-shape memory alloy (SMA) is very promising regarding cavitation resistance. The need of high vacuum conditions by thermal spraying processes, to avoid oxidation, has always been and still is the main obstacle for the widespread of NiTi as a coating material. This work deals with studying the effect of the different shroud concepts on the obtained oxide content and the phases of the obtained twin wire arc sprayed (TWAS) coatings. The concepts include the use of argon as a shield in gas shroud (GS) as well as the use of an extended air cap attachment as a massive shroud (MS). The use of MS-concept led to a significant decrease in oxide content and therefore was selected to spray pre-alloyed NiTi-SMA wires. The standoff distance between the MS-outlet and the substrate surface shows also an effect on the obtained phases and thus on the behavior of the obtained coatings. At lower standoff distance a pseudo-elastic behavior was obtained and therefore a higher cavitation and wear resistance. The use of argon as atomization and shield gas with a massive shroud could be a cost-effective alternative for vacuum process in case of spraying NiTi-SMA pre-alloyed feedstock materials.
