“…The majority of recent research articles citing Loghman-Estarki M. R.'s work have focused on TBC structure engineering, such as the development of multilayer TBC coatings, 184,185 and nanostructure TBC coatings. 21,186 Interestingly, due to the promising thermo-physical properties of high-entropy ceramics (HECs), the citing article by Xue Y. et al 187 developed a thermal barrier material based on HECs that has the composition of (La 0.2 -Nd 0.2 Sm 0.2 Eu 0.2 Gd 0.2 ) 2 Ce 2 O 7 or also called HECO. Thus, the anticipated research trend may dominantly focus on TBC structure engineering, such as multilayer structure, nanoscale structure, and the development of HEC based TBC.…”

“…Some reviews from the materials design to the failure mechanisms have been done to achieve a more satisfactory performance of TBCs against destructive type I hot corrosion. [16][17][18][19][20][21][22] Components coated with TBCs must be able to withstand intense heat, uctuating temperatures, and mechanical strains. For example, industrial gas turbine engines are expected to last up to 30 000 hours of operation.…”

“…Currently, the most effective method for enhancing the service temperature of the engine is the heat insulation protection technology provided by thermal barrier coatings (TBCs). TBCs consist of a heat-insulating ceramic layer, an oxidation-resistant and bond-enhancing intermediate layer, and a substrate made of nickel-based superalloy [4].…”

The uncertain service life of thermal barrier coatings (TBCs) imposes constraints on their secure application. In addressing this uncertainty, this study employs the Monte Carlo simulation method for reliability evaluation, quantifying the risk of TBC peeling. For reliability evaluation, the failure mode needs to be studied to determine failure criteria. The failure mode of high-speed rotating TBCs under gas thermal shock was studied by combining fluid dynamics simulations and experiments. Based on the main failure mode, the corresponding failure criterion was established using the energy release rate, and its limit state equation was derived. After considering the dispersion of parameters, the reliability of TBCs was quantitatively evaluated using failure probability and sensitivity analysis methods. The results show that the main mode is the fracture of the ceramic layer itself, exhibiting a distinctive top-down “step-like” thinning and peeling morphology. The centrifugal force emerges as the main driving force for this failure mode. The failure probability value on the top side of the blade is higher, signifying that coating failure is more likely at this location, aligning with the experimental findings. The key parameters influencing the reliability of TBCs are rotation speed, temperature, and the thermal expansion coefficient. This study offers a valuable strategy for the secure and reliable application of TBCs on aeroengine turbine blades.

“…Zirconia (ZrO 2 ), with its extensive applications including but not limited to thermal barrier coatings, catalysts or carriers, fuel cells, functional ceramics, and oxygen ion conductors, is notable for its unique polymorphism [ 1 , 2 , 3 , 4 , 5 ]. The key feature of zirconia’s polymorphism involves the transition among three crystalline structures: monoclinic (m), tetragonal (t), and cubic (c).…”

Zirconia (ZrO2) nanoparticles were synthesized using a solvothermal method under varying synthesis conditions, namely acidic, neutral, and alkaline. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were leveraged to investigate the phase evolution and topographical features in detail. The resulting crystal phase structures and grain sizes exhibited substantial variation based on these conditions. Notably, the acidic condition fostered a monoclinic phase in ZrO2, while the alkaline condition yielded a combination of tetragonal and monoclinic phases. In contrast, ZrO2 obtained under neutral conditions demonstrated a refinement in grain sizes, constrained within a 1 nm scale upon an 800 °C thermal treatment. This was accompanied by an important transformation from a monoclinic phase to tetragonal phase in the ZrO2. Furthermore, a rigorous examination of XPS data and a UV-visible spectrometer (UV-vis) analysis revealed the significant role of oxygen vacancies in phase stabilization. The notable emergence of new energy bands in ZrO2, in stark contrast to the intrinsic bands observed in a pure monoclinic sample, are attributed to these oxygen vacancies. This research offers valuable insights into the novel energy bands, phase stability, and optical absorption properties influenced by oxygen vacancies in ZrO2. Moreover, it proposes an innovative energy level model for zirconia, underpinning its applicability in diverse technological areas.
