“…The atomized precursor is used as a feedstock to transmit the chemical precursor by injecting this aqueous form solution into the plasma jet. It is also helpful for fast physical reactions inside the plasma region [62]. This method consists of organic or inorganic solvents, compounds of metallic-organic and inorganic salts used to complete the process [63].…”

Thermal barrier coating is critical for thermal insulation technology, making the underlying base metal capable of operating at a melting temperature of 1150 °C. By increasing the temperature of incoming gases, engineers can improve the thermal and mechanical performance of gas turbine blades and the piston cylinder arrangement. Recent developments in the field of thermal barrier coatings (TBCs) have made this material suitable for use in a variety of fields, including the aerospace and diesel engine industries. Changes in the turbine blade microstructure brought on by its operating environment determine how long and reliable it will be. In addition, the effectiveness of multi-layer, composite and functionally graded coatings depends heavily on the deposition procedures used to create them. This research aims to clarify the connection between workplace conditions, coating morphology and application methods. This article presents a high-level overview of the many coating processes and design procedures employed for TBCs to enhance the coating’s surface quality. To that end, this review is primarily concerned with the cultivation, processing and characteristics of engineered TBCs that have aided in the creation of specialized coatings for use in industrial settings.

“…Regarding the preparation of anode materials by spray pyrolysis techniques, most of the investigations are devoted to the preparation of Ni-YSZ and Ni-CGO powders [191][192][193][194][195][196][197][198][199][200] with spherical or core-shell morphologies. In general, these anodes exhibit improved electrochemical performance in terms of lower overpotential and ohmic losses, when compared to traditional Nicermets obtained by mixing powders.…”

“…For instance, Shimada et al reported a power density over 3 W cm –2 at 750 °C for a screen-printed SSC-SDC nanocomposite . Several nanocomposite cathodes have also been deposited directly by spray pyrolysis on the electrolyte, simplifying the fabrication process and improving the adherence and integrity to the substrate when compared to ink-based depositions. ,, This strategy has also been used to obtain Ni-YSZ anodes but, to the best of our knowledge, there are no studies on mixed oxide nanocomposites for fuel electrodes.…”

La 0.98 Cr 0.75 Mn 0.25 O 3−δ –Ce 0.9 Gd 0.1 O 1.95 (LCM-CGO) nanocomposite layers with different LCM contents, between 40 and 60 wt %, are prepared in a single step by a spray-pyrolysis deposition method and evaluated as both air and fuel electrodes for solid oxide fuel cells (SOFCs). The formation of fluorite (CGO) and perovskite (LCM) phases in the nanocomposite electrode is confirmed by different structural and microstructural techniques. The intimate mixture of LCM and CGO phases inhibits the grain growth, retaining the nanoscale microstructure even after annealing at 1000 °C with a grain size lower than 50 nm for LCM-CGO compared to 200 nm for pure LCM. The synergetic effect of nanosized LCM and CGO by combining their high electronic and ionic conductivity, respectively, leads to efficient and durable symmetrical electrodes. The best electrochemical properties are found for 50 wt % LCM-CGO, showing polarization resistance values of 0.29 and 0.09 Ω cm 2 at 750 °C in air and H 2 , respectively, compared to 2.05 and 1.9 Ω cm 2 for a screen-printed electrode with the same composition. This outstanding performance is mainly ascribed to the nanoscale electrode microstructure formed directly on the electrolyte at a relatively low temperature. These results reveal that the combination of different immiscible phases with different crystal structures and electrochemical properties could be a promising strategy to design highly efficient and durable air and fuel electrodes for SOFCs.
