Estimating the replicability of technology education research
Authors: Buckley Jeffrey , Hyland Tomás , Seery Niall
Published: November 2022

Technology education research is a growing field, with the rate of growth increasing over the last two decades. As the field grows, it is paramount that credibility is maintained in published findings. To date there is no evidence to suggest a lack trust is warranted, however in the midst of the replication crisis there is need to ensure continued rigour. This article presents a z-curve analysis of the replicability of quantitative research in technology education since 1983 using statcheck for automated data extraction. The results indicate that authors often mis-report p-values, typically due to rounding errors, with a small percentage (1.59%) of inconsistently reported p-values leading to decision errors in terms of statistical inference. With respect to replicability, overall it is estimated that 55.7% of reported quantitative results in technology education would replicate, however since 2020 this estimate appears to be increasing. These results do not indicate specific findings which are unlikely to replicate, but do suggest a need to invest effort in identifying studies which would have a high value in being replicated, particularly in the timeframe of work published from 2010 to 2020.
Destructive Interference of Light - Where Does the Energy Go?
Authors: Tadesse Henok
Published: November 2022

We already know the unconventional and inexplicable behavior of light/photons (and other quantum particles such as electrons) in the Which-Way quantum experiment and entanglement phenomena. In this paper we propose another quantum experiment using a Michelson interferometer. We start with an 'elementary' thought experiment. Suppose that a Michelson interferometer is set up so that the two light beams undergo complete constructive interference, with a single bright spot. Then the distance of one of the mirrors is slightly adjusted for a complete destructive interference: the bright spot disappears. The puzzle is: where does the light go? We suspect that, just like nature does not allow us to know which slit a photon has passed through in the double- slit experiment, nature may not allow us to know 'where the light goes' in the case of (complete) destructive interference. Although nature may not allow a direct measurement, we can understand by reasoning 'where the light goes' during complete destructive interference. This paper reveals the mystery. A simple quantum experiment based on the Michelson interferometer is proposed.

Published: November 2022

Applications of deep learning to the radio frequency (RF) domain have largely concentrated on the task of narrowband signal classification after the signals of interest have already been detected and extracted from a wideband capture. To encourage broader research with wideband operations, we introduce the WidebandSig53 (WBSig53) dataset which consists of 550 thousand synthetically-generated samples from 53 different signal classes containing approximately 2 million unique signals. We extend the TorchSig signal processing machine learning toolkit for open-source and customizable generation, augmentation, and processing of the WBSig53 dataset. We conduct experiments using state of the art (SoTA) convolutional neural networks and transformers with the WBSig53 dataset. We investigate the performance of signal detection tasks, i.e. detect the presence, time, and frequency of all signals present in the input data, as well as the performance of signal recognition tasks, where networks detect the presence, time, frequency, and modulation family of all signals present in the input data. Two main approaches to these tasks are evaluated with segmentation networks and object detection networks operating on complex input spectrograms. Finally, we conduct comparative analysis of the various approaches in terms of the networks' mean average precision, mean average recall, and the speed of inference.

Authors: Derrer-Merk Elfriede , Rodrigez María Fernanda Reyes , Soulsby Laura K. , Roper Louise , Bennett Kate Mary
Published: November 2022

Objectives: Relatively little is known about the lived experiences of older adults during the COVID-19 pandemic. We systematically review the international literature to understand the lived experiences of older adult’s experiences during the pandemic.Design and methodology: This study uses a meta-ethnographical approach to investigate the included studies. The analyses were undertaken with constructivist grounded theory. Results: 32 studies met the inclusion criteria and only five papers were of low quality. Most, but not all studies, were from the global north. We identified six themes: risk communication; discrimination; social connectivity; well-being; coping. Overall, the studies’ findings were varied and reflected different times during the pandemic. Studies reported about the impact of mass media messaging and its mostly negative impact on older adults. Many studies highlighted the impact of the COVID-19 pandemic on participants' social connectivity and well-being such as missing the proximity of loved ones and in consequence experienced and increase in anxiety, feeling of depression, or loneliness. Some studies focused on discrimination in particular studies investigating the experiences of LGBT and immigration participants. They found that the pandemic impacted on the participants well-being such as suicidal risk behaviour, loss of friendship, and increase mental health issues. Additionally, many studies reported how participants adapted to the change of lifestyle such as using new ways of communication, and following social distancing advice. Conclusion: The COVID-19 pandemic disrupted and impacted older adults’ well-being worldwide. Despite the cultural and socio-economic differences many commonalities were found. Studies described the impact of mass media reporting, discrimination, social connectivity, impact on well-being, and coping. The authors suggest that these findings need to be acknowledged for future pandemic strategies. Additionally, the process of policy-making needs to include older adults to address their particular needs. PROSPERO record [CRD42022331714]

Authors: Dykxhoorn Jennifer , Osborn David , Walters Kate , Kirkbride James Bowes , Gnani Shamini , Lazzarino Antonio
Published: November 2022

Background: Common mental disorders (CMD) including depression, anxiety, and stress are very common, but it is unclear whether the last two decades of social, economic, and political change have impacted incidence of CMD. This study explored longer-term temporal trends in the incidence of CMD in the UK. Methods: We used data from general practices in the UK (Clinical Practice Research Datalink) to estimate the incidence of news episodes of CMD, including of symptom, diagnosis, or pharmaceutical treatment. Trends were explored by age group, sex, ethnicity, deprivation, and physical comorbidity.Results: We included 29,480,164 individuals followed for 12.5 years on average (SD=6.4 years). The incidence of CMD episodes was 55.9 per 1,000 person-years in 2000 (95% CI 55.8–56.1), increasing to 79.6 per 1,000 person-years in 2019 (95% CI 79.5-79.8). Females had higher incidence rates, as did those living in more deprived areas. There were differing patterns of incidence by ethnic group, with a steeper increase in Asian, Black, and Mixed groups in recent years. We observed striking patterns by age over time, with rates in ages 16-24 increasing from 40.2 per 1,000 in 2000 (95% CI 39.8–40.5), to 107.8 per 1,000 in 2019 (95% CI 107.0–108.6). In contrast, the rates in those aged 55 or older decreased since 2014. Conclusions: Overall, the incidence of recorded CMD in UK general practice increased between 2000 and 2019 with a small decrease in 2020. We found large differences across demographic characteristics, which may have implications for primary, secondary, and tertiary prevention.

Evolution of intraplate magmatism atop a mantle plume: geochemical and chronological analysis of Shawahit Basalt, Harrat Rahat, Saudi Arabia
Authors: Roberts Gareth , Ball Patrick
Published: November 2022

Harrat Rahat is the largest volcanic  eld in Saudi Arabia and has been active from ~10 Ma to the present day. Due to its close proximity to important population centres, Harrat Rahat's recent eruptions, the Medinah lava flows (< 1.7 Ma), have been extensively studied to identify volcanic risk. However, the evolution of Harrat Rahat's most extensive and oldest lava flows, known collectively as the Shawahit Basalt (> 2.5 Ma), is poorly understood. In this study, we collected, dated and geochemically analyzed lava samples from Harrat Rahat, primarily targeting the under-sampled Shawahit unit. We 40Ar/39Ar dated 23 Shawahit samples that erupted between 9.4-2.7 Ma. Over the lifetime of Harrat Rahat, we observe a geochemical transition from predominantly tholeiitic to alkalic eruptions coupled with a counter-intuitive decrease in incompatible element concentrations. We attribute these changes to a decrease in melt productivity and a reduction in contamination by enriched lithospheric melts, respectively. Thermobarometric analysis of Harrat Rahat basalts indicates that these lavas were generated by melting of asthenospheric mantle with a potential temperature of ~1456 +50/-32 oC beneath lithosphere 50-60 km thick. These results indicate that volcanic activity at Harrat Rahat was initiated by the arrival of a mantle plume beneath lithosphere thinned by a combination of Red-Sea rifting and thermal erosion. Furthermore, we believe that this plume, either acting alone or in combination with a number of other plumes, is responsible for the formation of the Arabian swell, as well as much of the Neogene-recent intraplate volcanic activity observed across western Arabia. Our conclusions are consistent with a wide range of geochemical, seismologic, gravimetric, thermochronologic and geomorphologic observations.
Intergroup bias in dishonesty: In-group favouritism, out-group hostility, or both?
Authors: Martuza Jareef , Sjåstad Hallgeir , Thorbjørnsen Helge
Published: November 2022

Clear-cut lying for personal gain is widely considered immoral. But does it matter whom one is lying to? As individual decisions naturally occur in social context, the acceptability of dishonesty may depend on the group identity of the potential victim - posing a serious challenge for intergroup cooperation and societal polarization. To test this possibility, we will use the “mind game” paradigm to provide anonymous participants an economic incentive to lie without any detection risk, and randomly vary the group identity of their potential victim as an in-group member, out-group member, or a neutral no-group control. We will explore two research questions: (1) Are people more likely to cheat out-groups than in-groups for personal gain? (2) If true, is this intergroup bias in dishonesty driven by out-group hostility (lower moral cost of lying), in-group favoritism (higher moral cost of lying), or both? Experiment 1 (N=2100) will examine these questions by creating “minimal groups” in a nationally representative U.S. American sample. Experiment 2 (N=2100) will do the same using political groups, recruiting Democrat and Republican-voting participants. By studying anonymous risk-free decisions in the mind game, eliminating any cooperative or reputational consequences, the experiments will provide novel evidence on whether the internal moral cost of lying is a function of the group identity of the potential victim. We will also measure collective in-group identification and social-dominance orientation as potential moderators of the predicted effects. The findings will enhance our understanding of the group psychology of individual dishonesty.
Validating a Novel State Measure of Hypomanic-like Affect in a Young Adult Student Sample
Authors: Hammond Olivia , Ng Bernadette , Vannucci Caterina , Swancott Lucy , Artunduaga Sophie , Bartlett Uma , Cross Abigail , Burnett Heyes Stephanie
Published: November 2022

Background. Extreme positive mood characterises (hypo)mania and is associated with increased severity of bipolar disorders. However, the lack of recognition and effective measurement of hypomanic extreme positive mood means it is underreported and poorly understood. As existing affect and hypomanic symptom scales do not specifically measure hypomanic-like affective states, this study begins validation of a new state measure – the Hypomanic Mood Scale. Methods. 468 students completed an online survey consisting of validated state and trait measures of affect and mood disorder symptoms, alongside the novel HMS. Analysis focused on establishing the construct validity, content validity and construct reliability of the HMS.Results. The HMS had a two-factor structure, ‘active-elated’ and ‘irritable-unstable’. The ‘active-elated’ factor was internally reliable, despite overall poor internal consistency of the HMS and poor reliability when hypomanic-like irritation items were included. HMS scores were associated with past and enduring tendencies to experience hypomania, when controlling for current anxiety and depression symptoms. HMS items did not distinguish from general positive mood items on an existing affect scale.Limitations. As a primarily female student sample was used, findings cannot be generalised to general or clinical populations.Conclusions. Findings provide a promising start to the development of a novel hypomanic-like mood scale. Further research should focus on refining the scale and improving internal consistency of the hypomanic-like irritation factor. Successful development and validation of this measure will be useful for future development of simple and accessible methods of self-monitoring mood and tracking risk for patients e.g., medical mobile applications.
Developmental consistency in the use of subphonemic information during real-time sentence processing
Authors: Conwell Erin , Horvath Gregor , Kuznia Allyson , Agauas Stephen J.
Published: November 2022

Apparently homophonous sequences contain acoustic information that differentiates their meanings (Gahl, 2008; Quené, 1992). Adults use this information to segment embedded homophones (e.g., ham vs. hamster; Salverda, et al., 2003) in fluent speech. Whether children also do this is unknown, as is whether listeners of any age use such information to disambiguate lexical homophones. In two experiments, 48 English-speaking adults and 48 English-speaking 7- to- 10-year-old children viewed sets of four images and heard sentences containing phonemically identical sequences while their eye movements were continuously tracked. As in previous research, adults showed greater fixation of target meanings when the acoustic properties of an embedded homophone were consistent with the target than when they were consistent with the alternate interpretation. They did not show this difference for lexical homophones. Children’s behavior was similar to that of adults, indicating that the use of subphonemic information in homophone processing is consistent over development.
A Novel Approach for Constructing Personalized Networks from Longitudinal Perceived Causal Relations
Authors: Burger Julian , Andikkhash Vida , Jäger Nelly , Anderbro Therese , Blanken Tessa , Klintwall Lars
Published: November 2022

IntroductionThe network approach to psychopathology aims to solve problems with heterogeneity and comorbidity, as well as advance psychiatric precision medicine. Statistical relations in networks can be estimated from intensive longitudinal data, but causal interpretations of such networks are limited by strong statistical assumptions and the frequency of assessments heavily influences which relations can be discovered.ObjectiveAn alternative is to create networks from patient perceptions, which comes with other limitations such as retrospective bias. As a synthesis, we introduce the Longitudinal Perceived Causal Relations (L-PCR) approach.Methods20 participants screening positive for depression completed up to 28 days of brief assessments of experienced symptoms and perceived symptom-symptom influences. Quality criteria of this new method are introduced via a bootstrapping algorithm, answering questions such as “Which symptoms should be included in networks?”, “How many datapoints need to be collected to achieve stable networks?”, and “Does the network change over time?”.ResultsTo achieve stability, networks had to be created using only a core of frequently experienced symptoms, i.e. symptoms experienced during at least a third of days. About 40% of respondents achieved stable networks and only a few respondents exhibited changes in network structure across time. The method was time efficient (on average 7.4 minutes per day) and well received by participants.ConclusionsFuture directions of L-PCR include individualized core symptoms in a controlled clinical population, as well as additional assessment types such as counterfactual questions. Overall, L-PCR addresses several of the prevailing issues found in statistical networks and therefore provides a clinically-meaningful method for personalized analysis.
Locating what comes to mind in empirically derived representational spaces
Authors: Mills Tracey , Phillips Jonathan Scott
Published: November 2022

Real-world judgements and decisions often require choosing from an open-ended set of options which cannot be exhaustively considered before a choice is made. Recent work has found that the options people do consider tend to have particular features, such as high historical value. Here, we pursue the idea that option generation during decision making may reflect a more general mechanism for calling things to mind, by which relevant features in a context-appropriate representational space guide what comes to mind. In this paper, we evaluate this proposal primarily based on what comes to mind in different familiar categories. We first introduce an empirical approach for deriving the space of features that people use to represent items in a particular category and for locating the category members that come to mind within that space. We show that in both familiar and ad hoc categories, a category member's location along certain dimensions of the derived feature space predicts its likelihood of coming to mind. Next, we show that category members from these feature space locations come to mind by default in a way that is somewhat impervious to conscious control. We then demonstrate that the extent to which a given dimension is a predictor of what comes to mind within a category is related to how relevant that feature is for representing the category in question, using a novel measure of general feature relevance. Finally, we illustrate the usefulness of this framework in the context of a decision making task. We close with the proposal that people call category members to mind according to their location in representational space, specifically based on the predicted usefulness of considering category members with particular features.

Pubertal processes are associated with structural brain development, but studies have produced inconsistent findings that may relate to different measurements of puberty. Measuring both hormones and physical characteristics is important for capturing variation in neurobiological development. The current study explored associations between cortical thickness and latent factors from multi-method pubertal data in 174 early adolescent girls aged 10-13 years in the Transitions in Adolescent Girls (TAG) Study. Our multi-method approach used self-reported physical characteristics and hormone levels (dehydroepiandrosterone (DHEA), testosterone (T), and estradiol (E2) from saliva) to estimate an overall pubertal factor and for each process of adrenarche and gonadarche. There were negative associations between the overall puberty factor representing later stage and thickness in the posterior cortex, including the occipital cortices and extending laterally to the parietal lobe. However, the multi-method latent factor had weaker cortical associations when examining the adnearcheal process alone, suggesting physical characteristics and hormones capture different aspects of neurobiological development during adrenarche. Controlling for age weakened some of these associations. These findings show that associations between pubertal stage and cortical thickness differ depending on the measurement method and the pubertal process, and both should be considered in future confirmatory studies on the developing brain.

Published: November 2022

The efforts and talents of Nigerian creative artists have not turned into proportionate economic benefits. However, Non-Fungible Tokens (NFT) and their marketplaces are causing a revolution in the gaming, literature, art and music industries. Despite these opportunities, NFTs hold, of concern is the effectiveness, awareness and risks it poses to Nigerian visual art stakeholders. Through a triangular method, data was collected, analysed and discussed utilising media economics and the diffusion of innovation theories. A total of 28 stakeholders, predominantly artists, including art collectors and copyright regulators, showed that early adopters in Nigeria consider NFT marketplaces for showcasing and selling digital artworks. Notwithstanding, this trust is not seen when it comes to copyright-ability. The study also showcases various policy, structural and economic issues limiting Nigerian art space besides technology adoption. Nigerian creatives must keep an eye on the evolution of NFTs to aid their sustainable growth. Although pirated creative works have been sold on the streets of Nigeria over the years, NFTs can help Nigerian creatives earn on the streets of the metaverse.

Objetivo: determinar la importancia epidemiológica de la hipertensión arterial como factor de riesgo cardiovascular en diferentes estudios realizados a nivel mundial, en Latinoamérica y Colombia. Metodología: se realizó una búsqueda de la literatura científica en las bases de datos de PudMed/Medline, Scielo, LILACS, así como también en revistas médicas y textos publicados por el Ministerio de Salud y Protección Social de Colombia. Discusión y conclusiones: más de 90% de los pacientes hipertensos padecen la forma primaria de la enfermedad, la cual está asociada con un aumento de la resistencia vascular periférica. Las características socioeconómicas de los países y el nivel educativo individual se relacionan con la prevalencia y el manejo adecuado de esta patología. El aumento en la prevalencia de las enfermedades crónicas, sumado a eventos históricos de importancia, fueron determinantes para el desarrollo de estudios epidemiológicos mundiales como el Framingham Heart Study. En América Latina y en Colombia se han realizado diferentes estudios que permiten establecer datos relacionados con la hipertensión arterial, demostrando cifras alarmantes en cuanto al conocimiento, tratamiento y control de esta condición, por lo cual, surge la necesidad de establecer programas para la detección de pacientes hipertensos con el fin de generar estrategias que disminuyan de manera significativa las enfermedades cardiovasculares.

La neurosífilis es la enfermedad del sistema nervioso central (SNC) causada por Treponema pallidum, perteneciente al grupo de las espiroquetas; se puede presentar en pacientes inmunocompetentes pero existe una asociación mayor con el virus de inmunodeficiencia humana (VIH). Estos casos son más severos y con manifestaciones neurológicas variables. Si bien la forma típica es la más frecuente, existen expresiones atípicas que pueden llegar a presentarse en 30% de los casos según los estudios radiológicos, por lo cual es importante reconocerlas a fin de garantizar un diagnóstico temprano y una intervención oportuna. No solo es un problema de salud pública por su prevalencia sino también por el amplio espectro clínico que le ha valido el nombre de gran simuladora, siendo desconocidas en muchas ocasiones por los médicos de atención primaria. El siguiente trabajo ha sido planteado con base en tres casos clínicos (2 de vasculitis en SNC, una panuveítis) con el objetivo de desmitificar los tiempos de presentación y aclarar las manifestaciones clínicas que comprometen el SNC, tratando de precisar el diagnóstico para la realización de un tratamiento pertinente y oportuno que reduzca las secuelas.

Environmental Health Risk Assessment (EHRA) is a study to understand the condition of sanitation facilities and behaviors that pose a risk to public health. Wanasari Village is one of the tourist destinations that can have a very complex impact, especially on aspects of environmental health. The purpose of this study was to obtain representative data on the sanitation facilities condition and community behavior in Wanasari Village which are at risk for environmental health. This study uses a stratified random sampling technique with the sample in Wanasari Village as a target study area. The households visited in each Banjar were randomly selected and then interviewed according to the available questionnaires and continued to the next sample until 100 respondents were found for 5 Banjars which were then analyzed. The condition of the facilities and the behavior of the community based on the results of the questionnaire stated that the inadequate facilities were facilities for domestic wastewater and problems with stagnant water. Results of the sanitation analysis risk index with high risk are found in Banjar Wanasari Baleran and moderate risk in Banjar Periyukti with the main problems in domestic wastewater and stagnant water. Banjar Abianlalang, Banjar Wanasari Belodan, and Banjar Wanasari Tengah with the main problems in solid waste, domestic wastewater, and stagnant water are included in the category of less risky areas.

Sea Water Reverse Osmosis (SWRO) reject water produced by PT Cirebon Electric Power has not been optimally utilized. In this research, a study of the characteristics of SWRO reject water was carried out to determine important properties such as turbidity, conductivity, pH and salinity. This characteristic is important as a basis for consideration of SWRO reject water applications. In addition, data were taken from a fairly long period of 5 years of SWRO operation (2016-2021) so that the consistency of the data can be known. The results showed that SWRO reject water had low turbidity (0.18±0.08 NTU), high conductivity of ca. 76.000 µS/cm, neutral pH and high salinity (4.6±0.3%). The study of the utilization of SWRO reject water was then carried out, namely as an electrolyte for salt water lamps and as raw material for making salt. The results showed that SWRO reject water can be used as an electrolyte for salt water lamps which produces a voltage potential up to 1.4 Volts (20% higher than seawater electrolyte). As a raw material for salt, the salt produced has excellent characteristics (eg 99% NaCl) and complies with SNI 3556:2016, except for the KIO3 content.

Mercury pollution in gold ore processing wastewater can cause environmental and health problems. A large amount of mercury pollution causes neurological disease, paralysis, loss of sense of taste, irregular speech, and death. One effective method to reduce mercury amount in the environment is adsorption. Adsorption performance is affected by several factors such as surface area of material, deacetylation degree (DD), and adsorption condition, which is indicated by contact time and mercury concentration. Nanochitosan is used in this research. Effect of deacetylation degree (85%; 87%; 95%), contact time (30;60;90;120 minutes), and variation of mercury concentration (5;10;15;20;25;30 ppm) on adsorption performance was investigated in this research. Nanochitosan in this research is characterized by FTIR, SEM-EDX, BET-BJH, and pH PZC. AAS measures adsorption performance in this research. The result shows that nanochitosan, which has the best adsorption performance, is nanochitosan with a deacetylation degree of 95%, at a contact time of 60 minutes, and mercury concentration is 15 ppm.

Palm oil mill effluent (POME) is palm oil processing industrial waste that cannot be discharged directly into water bodies. Therefore, this waste must be treated. One method that can be used to treat it is coagulation. The purpose of this study was to investigate the effect of coagulant doses on the coagulation process for treating the POME through experimental and kinetic analysis. The alum dose was varied to 1, 3, 5, 10, 15 g/L. The volume of treated waste was 1 L. Before adding alum, the pH of POME was adjusted to 7.0 with the addition of technical grade NaOH. The coagulation process was carried out for 180 minutes at room temperature. Every 20 minutes, the pH of the liquid was measured and a fluid sample as much as ±50 mL was taken to be settled for 24 hours. Next, the total suspended solid (TSS) concentration in the supernatant was analyzed. The results showed that the addition of alum could decrease the liquid pH and increase the TSS of the liquid. The coagulation process for 180 minutes resulted in a TSS reduction efficiency of 33.3, 33.3, 37.1, 1.7, -17.8% at alum doses of 1, 3, 5, 10, 15 g/L respectively. The first-order kinetic model provided a better prediction than the second-order kinetic model with R2 values of 0.7876-0.9707 and 0.2746-0.8912, respectively.

What would be the most appropriate parameters, namely, gas temperature and gas pressure, for cold spraying of a given feedstock material? This question is the focus of the present contribution. Initially, it is shown that main coating characteristics can be described as a unique function of a dimensionless parameter, defined as the ratio of particle velocity to critical velocity. Subsequently, these velocities and the respective ratio are worked out and expressed explicitly in terms of key process and material parameters, such as gas temperature and particle size. In this way, final properties of cold-sprayed deposits are linked directly to primary cold-spray parameters. Moreover, it is shown that the window of deposition, as well as the relationship between final properties of the deposit and the spraying conditions, can be incorporated conveniently into simple 2-D diagrams, showing contours of the velocity ratio, or the desired coating property, on the plane of the primary process parameters. Based on these diagrams, the process parameters related to a given coating property can be identified and selected, without a need to refer to intermediate variables such as particle velocity. The paper includes examples of the application of these maps for cold spraying of copper.

Cr3C2-NiCr coatings are commonly used to provide abrasion and erosion wear resistance on the surface of components, in particular for corrosive and atmospheric high-temperature environments. For these classical and new applications the knowledge of the thermophysical properties is highly important. In the present work the dependence of the heat conductivity on temperature of two HVOF-sprayed Cr3C2-25NiCr-coatings prepared by a liquid-fuelled HVOF-process from two different feedstock powders from room temperature up to 700 °C was determined. Thermal diffusivities, density functions, specific heat capacities and coefficient of thermal expansion (CTE) were measured in order to compute the heat conductivity for the coatings. All measurements were performed twice (as-sprayed and after a first thermal cycle) in order to take into account the structural and compositional changes. XRD and FESEM studies were performed in order to characterize the phase compositions and microstructures in the as-sprayed and heat-treated states. Heat conductivities (average of the two coatings) ranging from about 11 W/(mK) at 50°C up to about 20 W/(mK) at 700°C were determined. Differences between the two coatings were clearly detectable. The heat conductivity of the Cr3C2-NiCr coatings is significantly lower than determined previously for a WC-17%Co coating.
