“…Nonetheless, plasmas containing a dispersed liquid phase in the form of aerosols or droplets also have a long history in thermal plasmas: e.g. analytical techniques using inductively coupled plasma, production of advanced materials in the form of coatings [31,32] or nano-particles [33]. In the emerging coating technology of plasma spraying of liquid feedstock, the material is injected in the form of droplets of suspensions of nano-or micro-sized particles or droplets of chemical solutions.…”

“…In the emerging coating technology of plasma spraying of liquid feedstock, the material is injected in the form of droplets of suspensions of nano-or micro-sized particles or droplets of chemical solutions. In the latter case, coating material synthesis and deposition occurs in a single process [32]. Similar approaches are used in low temperature plasmas [34].…”

“…Solution precursor plasma spray (SPPS), as shown in Figure 8, involves feeding an aqueous or non-aqueous solution into the plasma to form the coating, and the solution may contain cation(s) for forming the oxide of interest, while in a conventional plasma spray process, a flow of the powder of the coating material is often provided [32]. A similar method to SPPS is so called SPS (suspension plasma spray) in which a liquid with particle suspension is fed into a heated jet.…”

Abstract. The aim of this paper is to present a critical analysis of existing methodologies, approaches and strategies used to develop materials systems and coatings for uses in extreme environments. The extreme or harsh conditions encompass a large variety of in-service forms such as: extreme temperatures, abrasion, corrosion, impact and radiation that can exist in various applications such as those associated with aerospace and aeronautical engineering, land and marine transport, manufacturing machinery, and even microelectronics products. This article describes how working environment and required service performance of a particular part or structure could affect the choice of materials and surfaces to which it is composed. In addition, the paper explains the relevance that abusive working environments have for industry, especially relating to their costs, being followed by an overview of surface deposition approaches that are currently popularly used to improve performance of mechanical devices that need to combat adverse conditions. Finally, a material system and three kinds of protective coatings that could be used in applications in extreme conditions are described. The critical review is an outcome of the strategic review from the EU H2020 SUPERMAT project which deals with materials and manufacture for the products/structural parts used in extreme conditions. Keywords: extreme environment / material system / surface treatment / coating / economic impacts / case study Extreme environment and material-related issuesA harsh environment could be any environment that impedes the operation of a device/system. Many types of the conditions could be considered to be harsh, such as: extreme pressure/temperature, shock, vibration, chemical reactivity, radiation, corrosion and humidity, ranging from the applications in, such as alloy production, component manufacture, transport and biomedical implants [1] while the energy sector faces additional harsh environment such as that in various power plants [2], some of such examples being listed below: -Transport: Automobiles and airplanes that are operated in extreme conditions, being exampled by engines components and high-friction paired parts; -Energy: The devices/pipelines/components used for energy conversions, transports and storages, which faces high-temperature, various kinds of mediums and nuclear/chemical reactions, and suffer from corrosion and fatigue failures; -Manufacturing: Tools (e.g. cutting tools, dies and moulds, welding tools, high-temperature nozzles, etc.) used in manufacturing processes;

“…It has further been realized that, apart from the particles formed in-flight, any unpyrolyzed precursor impacting the preheated substrate is another crucial factor influencing the microstructure of the coating formed. The gradually improved understanding of the SPPS process in general has been well summarized in some excellent reviews that have periodically appeared in literature (Ref [49][50][51][52].…”

Liquid Feedstock Plasma Spraying: An Emerging Process for Advanced Thermal Barrier Coatings

et al. 2017

View full text Add to dashboard Cite

Liquid feedstock plasma spraying (LFPS) involves deposition of ultrafine droplets of suspensions or solution precursors (typically ranging from nano-to submicron size) and permits production of coatings with unique microstructures that are promising for advanced thermal barrier coating (TBC) applications. This paper reviews the recent progress arising from efforts devoted to development of high-performance TBCs using the LFPS approach. Advancements in both suspension plasma spraying and solution precursor plasma spraying, which constitute the two main variants of LFPS, are presented. Results illustrating the different types of the microstructures that can be realized in LFPS through appropriate process parameter control, model-assisted assessment of influence of coating defects on thermo-mechanical properties and the complex interplay between pore coarsening, sintering and crystallite growth in governing thermal conductivity are summarized. The enhancement in functional performances/lifetime possible in LFPS TBCs with multilayered architectures and by incorporating new pyrochlore chemistries such as gadolinium zirconate, besides the conventional single 8 wt.% yttria-stabilized zirconia insulating ceramic layer, is specifically highlighted.
