UK Psychology PhD Researchers' Knowledge, Perceptions, and Experiences of Open Science
Authors: Pownall Madeleine , Terry Jenny , Collins Elizabeth , Sladekova Martina , Jones Abigail Rhian Ruth
Published: November 2022

To advance the goals and values of open science, it is vital that the next generation of researchers, i.e., PhD researchers, are supported in adopting open science practices. However, to date, there is no comprehensive understanding of psychology PhD researchers’ knowledge, perceptions, and experiences with open science in a UK context. The present study used a pre-registered mixed methods design to fill this gap in the literature, by surveying psychology PhD students in the UK (n = 196) on their experiences with open science, perceptions of open science, and knowledge of open science tools and practices. Our findings demonstrate that while attitudes towards questionable research practices were consistently high, knowledge and perceptions of open science tools and practices varied considerably across PhD researchers. In particular, supervisory support and guidance with open science practices was mixed across participants. Perceived benefits of engaging with open science included benefits to employability, signalling researcher credibility, sharing learning and resources, building collaboration and relationships, and wider dissemination of PhD researchers’ work. Perceived barriers included lack of time, financial reasons, fear of scooping, fear of judgement or criticism, and incompatibility with research paradigms (e.g., qualitative research). Implications for policy, including British Psychological Society training and support, are discussed.
Assigning Gender Role in Chitra Banerjee Divakaruni's Sister of My Heart
Authors: Bhusal Damodar
Published: November 2022

Chitra Banerjee Divakaruni through her novel Sister of My Heart unveils the position of women and their roles assigned in Indian patriarchal society and their effort to overthrow the biased attitude of male. As its theoretical tool it utilizes western version of liberal feminism and gender theory as stated by David Glover and Cora Kaplan. In doing so it aims at examining the reality of patriarchal ideology which considers women as second class citizen and maternal vessels. It reveals the pathetic condition of the protagonist, Anju and Sudha. They have not got the role of independent agents in the society but treated as play things. They are taught to be submissive from the very beginning of their life. The demarcation line has been drawn in the name of Bidhata Purush who also does not come to write their fortune. As a result, directly or indirectly they are engaged in their subservient lives. It is patriarchal ideology which makes them feminine and masculine, which assigns different roles, rights and responsibilities in order to make subservient. This paper concludes that the writer's, Chitra Banerjee Divakaruni’s work exposes the male domination upon women in the Indian society.

The usage of the female body in Abhay Shrestha's short story "Sumruma Draupadi," whichis based on the popular conception of the female body, is presented in the current researchusing a feminist critical methodology. It is mostly based on Michel Foucault's theory andthe notion of the feminine body put out by Lucy Irigieri and Julia Kristeva. The data for thenarrative analysis of the beliefs about the female body has been gathered using the textualanalysis approach, which is based on the library study method. On the basis of religion andsocietal ideals, the patriarchal social philosophy has oppressed women in the narrative"Sumruma Draupadi," making them subordinate and robbing them of their rights. Males'srights over women's bodies in this narrative, as well as women's need to be objectified formen to feel whole, have all been studied in this study. Men also have rights over women'sbodies in a society where men predominate. According to the study's findings, women'sbodies are exploited and oppressed in the tale that is being told, and their awareness hasbeen aroused to fight against this and seek for self-existence.}

Novel Approaches for Thermal Spray Deposition of Fully Dense Ceramic and Metal Coatings with Well Bonded Lamellae
Authors: Li C. , Yao S. , Tian J. , Li C. , Yang G. , Luo X. , Wei Y.
Published: November 2022

It has been well accepted that thermal sprayings present a typical lamellar structure with limited lamellar interface bonding. It has been a great challenge to deposit a fully dense coating with fully bonded lamellae. In this report, three different novel approaches are introduced to deposit fully dense ceramic coatings and metal alloy coatings. With the deposition of a specific ceramic coating, it was found that there exists an intrinsic bonding temperature corresponding to the glass transient temperature of spray material. A chemical bonding is formed at the interface upon splatting of a molten ceramic droplet, as far as the maximum interface temperature between the spreading splat and the solid splat reaches over the intrinsic bonding temperature. Moreover, it will be presented that a simple critical bonding temperature in a linear relation with the melting point of coating materials can be utilized to deposit fully dense ceramic coatings by controlling the deposition temperature. Furthermore, with metal alloy coatings, a self-bonding mechanism is proposed utilizing the ultrahigh temperature molten droplet for dense coating with fully bonded lamellae. Using specially designed core-shell structured powders, the investigators demonstrated that a bulk-like metal coating is deposited by creating ultra-high temperature molten droplet. It will be found that such coatings present excellent properties and performance comparable to bulk materials. Moreover, it will be shown that, for ductile metal alloys, the solution-impermeable dense metal coatings can be deposited by using the novel in-situ shot-peening assisted cold spraying.
The Arc Movement as a Source of Process Instability for Single-Cathode-Anode Systems – A New Method for Direct Investigation
Authors: Thomas G. , Mihm S. , Limburg M. , Gruner H.
Published: November 2022

The almost uncontrollable arc movement in a single-cathode-anode system limits the efficiency and process stability of this global used DC plasma spraying technique. A successful approach to stabilize the arc anode attachment and thus to increase process efficiency was the replacement of the convergent-cylindrical nozzle geometry by a convergent-divergent nozzle geometry with Laval contour. However, the advantages of this nozzle design were connected to an increased anode erosion caused by an excessive heat input from the anode attachment of the arc. Prerequisite for an optimization of the arc movement is its technical measurement and the dedicated correlation out of it with the plasma jet and the trajectory of injected powder particles. For this purpose Technical University of Berlin developed a new optical analysis method based on high-speed video recording to examine the arc movement, its position and intensity. The software based data together with the simultaneous measured voltage of the corresponding DC-arc clearly show for example the dependence of the arc movement from the position of the cathode tip in relation to center axis of the anode, impressively demonstrated for a new three-zone anode (convergent, conical and divergent). Thus a new tool is given to the developer of new anode geometries for increasing process efficiency and the lifetime of the single-cathode-anode system.
Investigation of the Usefulness of Particle Jet Monitoring in a Production Environment
Authors: Leblanc L. , Hinckley R. , Spinicci C.
Published: November 2022

In the thermal spray process, particle state at impact is among the key factors influencing the quality, characteristics and properties of the deposit formed. Measuring and eventually controlling in-flight particle jet characteristics can help ensure the repeatability of desired coating properties. Moreover, monitoring particle jet can lead to cost savings by allowing replacement of consumable parts on a need-basis rather than on a preventive-basis. However, successful use of in-flight particle sensors in a production environment requires developing an implementation strategy that minimizes impact on coating cycle time, limits operator intervention and reduces analysis time, while still generating useful data. The usefulness of in-flight particle sensor in a high yield production environment is investigated. A preliminary study was first conducted to define a strategy to implement the data acquisition process using an ensemble in-flight particle monitoring system that allows real-time measurements of average particle temperature and velocity and overall particle jet profile. Data was collected to capture representative torch and particle jet behaviors over the life of several consumable hardware sets. Evolution of the particle jet parameters over time is compared to that of some of the process parameters, as well as to the deposition efficiency and one selected characteristic of the coating deposited. Some trends are identified, and potential benefits and drawbacks of using in-flight particle monitoring in a high yield production environment are highlighted.
Metallization of Various Polymers by Cold Spray
Authors: Che H. , Vo P. , Yue S.
Published: November 2022

Previous results at McGill University have shown that metallic coatings can be successfully cold sprayed onto polymeric substrates. This paper studies the cold sprayability of various metal powders on different polymeric substrates. Five different substrates were used, including carbon fibre reinforced polymer (CFRP), acrylonitrile butadiene styrene (ABS), polyether ether ketone (PEEK), polyethylenimine (PEI); mild steel was also used as a bench mark substrate. The CFRP used in this work has a thermosetting matrix, and the ABS, PEEK, and PEI are all thermoplastic polymers, with different glass transition temperatures as well as a number of distinct mechanical properties. Three metal powders, tin, copper and iron, were cold sprayed with both a low-pressure system and a high-pressure system at various conditions. In general, cold spray on the thermoplastic polymers rendered more positive results than the thermosetting polymers, due to the local thermal softening mechanism in the thermoplastics. Thick copper coatings were successfully deposited on PEEK and PEI.
A Case Study of Repair Work on Ship Engine Valve Stems
Authors: Nielsen P. T. , Bangsgaard D. B. , Soerensen K. G. , Pallesen P.
Published: November 2022

The degradation mechanisms of machine parts are well-known facts, usually resulting in replacement of components. However, in some cases, for instance, parts for large ship engines, repair will often seem more attractive. Time-wise, the vessel’s down-time will be reduced and the investment will be lower. This paper describes repair work performed on valve stems from a 52-year-old ship engine. Due to this long time in operation, the stems were damaged by wear and were no longer functional. The requirements for the stems were scarcely documented stating only a few specific requirements; therefore a short study of the possibilities concerning rebuild material and application method was initiated. This paper illuminates the manufacturing process used; twin wire arc spraying with Monel as the rebuild material. Monel is chosen to meet the requirements for hardness and the subsequent high precision machining. In addition, the mechanical and metallurgical properties of the rebuild coating are examined in regard to adhesion, microstructure and hardness to interpret and support the functionality.
Thermally Sprayed Porous Copper Coatings for Capillary Transport of Liquids
Authors: Feng C. , Yugeswaran S. , Chandra S.
Published: November 2022

Porous copper coatings, which act as wicks for liquid transport, were fabricated using a flame spraying process. Copper and aluminum powders were fed independently into the spray torch and deposited on copper substrates to form a composite coating. The aluminum was subsequently removed using chemical leaching leaving a porous copper coating behind. Varying the feed rate of aluminum powder allowed the coating porosity to be controlled. Channels to enhance liquid flow were made in some of the porous copper coatings by placing pieces of aluminum wire mesh on the copper substrate before spraying. During spraying the sprayed powders passed through the mesh opening and created pyramid shaped arrays on the substrates. The groove width was controlled by using different wire mesh sizes. Coatings were made with porosity varying from 2 to 44 %, and groove width ranging from 0.16 to 0.53 mm. The capillary performance of the coatings was evaluated experimentally by measuring the rate of rise of ethanol in the coatings. The rate of rise increased with coating porosity, and decreased with groove width.

Several surface preparation techniques are being used like grit blasting, HP water jet roughening as well as mechanical roughening for the preparation of Aluminum cylinder bore surfaces before a thermal spraying can be applied. However, in case of spray-repaired CI cast iron engine blocks the conventional mechanical roughening processes - using cutting inserts with small dovetail-undercut geometry - are not applicable due to the high hardness and high material toughness. Therefore such CI engine blocks are bored oversize in order to remove the bore wear damage and subsequently this rough-machined surface is coated by a NiAl-bond coating material in order to provide sufficient bond strength for the functional top coating material. In this paper it will be demonstrated that the 2-step spray-repair process can be replaced by a single-step process by using a new diamond-roll-roughening method. This process leads to significant higher bond strength values than the conventional process, including the bond coating material. PAT Adhesion test results as well as microstructural cross sections of coated cylinder bores will be presented. The principle of the roll-roughening process is outlined. In addition it will be shown that different mechanical roughening methods can be combined to obtain high bond strength values for spray-repaired aluminum blocks which require a higher coating thickness to compensate for the depth of the original mechanical bore activation.

HVOF processes represent the state of art for the spray deposition of wear and corrosion resistant coatings since their supersonic gas velocities in combination with moderate flame temperatures allow the deposition of optimal coatings with very high bond strengths, fine surface finishes and low oxide levels. However, new generation coating materials (fine powders), stringent quality requirements and the high productivity demanded by the industry, push the HVOF technologies to their limits. Recently, a novel air-oxygen controlled high velocity combustion process has been development by Tecnalia. The system operates within the supersonic regime using a broad range of fuel/oxidant ratios thanks to the use of air-oxygen mixtures and a carefully optimized gun design. Extremely low flame temperatures can be achieved while keeping a supersonic flow of combustion products, thus allowing the solid state deposition of almost all industrially relevant metal alloys with superior deposit qualities. In this work, a systematic investigation of the influence of the powder particle size and gun configuration on resulting coating microstructural features has been performed. For comparison, two fine structured commercially available WC10Co4Cr powders with different particle size distributions have been investigated. The coating structure has been characterized with by high resolution SEM cross-section imaging and X-ray diffraction analysis. Resulting coatings are characterized by highly dense structures, a high retention of the primary carbides, average microhardness of up 1885 HV0.3 and fracture toughness varying between 3 and 7 MPa.m-1/2 depending on the powder particle size distribution and the process conditions used.

Published: November 2022

The authors performed a time-dependent, three-dimensional numerical simulation of a non-transferred DC plasma spray with externally applied magnetic fields. Compressible Navier-Stokes equations with MHD source terms and Maxwell's equations were used as the governing equations for plasma flows. In the simulation, two operating conditions, electric currents and strength of externally applied magnetic fields, were parametrically varied in a range of 300 A to 500 A and 0.2 T to 0.8 T, respectively. Numerical results show that the application of strong magnetic fields such as 0.4 T and 0.8 T is recommended for an anode arc rotation leading to elongating an anode lifetime. A voltage variation due to the anode arc rotation shows periodic behavior with a small amplitude, which is expected to be good for plasma spraying processes. Lagrangian approach was used to track injected particles in the plasma jet and the particle temperature and position distributions on a cross section normal to the central axis of spray were studied. Swirl flows induced by the arc rotation hinder the particles from reaching the hot plasma jet. Our numerical results demonstrated that injecting particles in the opposite direction to the swirl flow is an effective way to heat the particles.

Published: November 2022

At present, main bearings in wind turbines are equipped with rolling bearings without exception. Sliding bearings instead can offer a number of advantages, including easier maintenance and extended lifetime. While conventional manufacturing processes for large sliding bearings face their limits regarding processable materials, thermal spraying can provide an effective alternative to meet the requirements by applying coating systems on the bearing surfaces. Within this study a wide range of different feedstock materials based on standard bearing materials and common wear and friction reducing coating systems are investigated. The coatings are tested on tribometers based on the load distribution within the main bearing at critical operating conditions of the wind turbine gained from a validated simulation model. A tribological methodology is developed to investigate the application related properties of the thermally sprayed coatings. The effects of load and geometry of the counter body on the friction and wear behavior of the coatings are investigated using a pin-on-disc and a modified high-load ring-on-disc tribometer. The presented results provide a major contribution to the purpose of identifying an appropriate coating system to meet the requirements of slow-moving and highly loaded sliding bearings.
An Assessment of Thermal Spray Technologies for Deposition of Environmental Barrier Coatings (EBC)
Authors: Bakan E. , Mauer G. , Vaßen R.
Published: November 2022

Environmental barrier coatings (EBC) are currently being investigated to protect ceramic matrix composite (CMC) turbine engine components in water-vapor rich combustion environments. Dense, crack-free, uniform and well-adhered coatings are demanded for this purpose. This paper represents an assessment of different thermal spray techniques for deposition of Yb2Si2O7 and silicon (Si) EBC layers. Plasma spraying of refractory silicates is known to be complicated by undesired glass transition due to rapid solidification as well as evaporation of Si-bearing species during spraying. Plasma spraying of low-density Si also requires careful optimizations as it tends to oxidize during spraying, particularly at atmospheric conditions. Bearing these problems in mind, the Yb2Si2O7 coatings were deposited by atmospheric plasma spraying (APS), high-velocity oxygen-fuel spraying (HVOF), and plasma-spray physical vapor deposition (PS-PVD) techniques. As-sprayed microstructure, amorphous content and phase composition of the coatings were analyzed. Based on the findings, the advantages and disadvantages of each method over other techniques are discussed with respect to process parameters and material properties.

Published: November 2022

A high electromagnetic field (0.3 T-Teslas) was applied during the solidification of Ni-based alloyed splats. Ni, NiCr, NiCrAl, NiCrBSiFe powders were deposited over steel polished substrates using a flame spray and a plasma spray torch. A strong electromagnet was used to produce sufficient magnetic field to induce effects over the splats during solidification. A remarkable change in splat morphology and chemical segregation was identified specially in NiCrBSiFe and the other alloys. Optical microscopy, surface profilometry, and SEM images revealed changes in the regular cracking trends, splashing, and thickness of the splats. This experimental study discusses the possible explanations for this phenomena. The adherence of the coating is the main property to be analyzed with the goal of improving the mechanical interlocking, and therefore, adhesion by engineering the applied electromagnetic field.
Effect of Substrate Roughness and Thickness on the Gas-Substrate Convective Heat Transfer During Cold Spraying
Authors: Mahdavi A. , McDonald A.
Published: November 2022

In this study, the effect of the substrate roughness and thickness on the heat transfer coefficient of the impinging air jet upon a flat substrate was investigated. A low-pressure cold spraying unit was used to generate a compressed air jet that impinged on a flat substrate. A detailed mathematical model was developed and coupled with experimental data to determine the heat transfer coefficient and surface temperature of the substrate. It was found that increasing the roughness of the substrate enhanced the heat exchange between the impinging air jet and the substrate. As a result, higher surface temperatures on the rough substrate were measured. It was further found that the Nusselt number that was predicted by the model was independent of the thickness of the substrate. The results of the current study were aimed to cover the influential substrate parameters on surface temperature of the substrate that eventually can affect the final quality of the cold-sprayed coatings.

Boiler tube failure is the number one source of forced outages in all coal-fired and biomass-fired power generation plants. It is estimated that plants lose approximately 6% of their power generation annually, due to boiler tube leaks. The major causes for premature tube failure are excessive fireside boiler tube erosion and corrosion caused by impact, abrasive wear, oxidation and molten corrosion of low eutectic alloys.
