Properties and Performance of High-Purity Thermal Barrier Coatings

, 2007
It was found that the content of impurity oxides in 7YSZ, such as SiO2 and Al2O3, has a significant effect on coating sintering resistance and phase stability of 7YSZ thermal barrier coatings (TBCs).

Outstanding 1200 °C Oxidation Resistance in a Novel Multi-Principal Element Alloy via Lattice Distortion-Induced Diffusion Suppression. [PDF]

Adv Sci (Weinh)
The unique lamellar structure of the eutectic alloy promotes selective oxidation of Al initially, while lattice distortion‐induced diffusion suppression slows oxide growth during steady state. Combining these strategies, a Multi‐Principal Element Alloy with excellent oxidation resistance at 1200℃ was designed.

Heat Transfer Through Plasma-Sprayed Thermal Barrier Coatings in Gas Turbines: A Review of Recent Work

, 2009
A review is presented of how heat transfer takes place in plasma-sprayed (zirconia-based) thermal barrier coatings (TBCs) during operation of gas turbines. These characteristics of TBCs are naturally of central importance to their function. Current state-

Investigation of delamination mechanisms during a laser drilling on a cobalt-base superalloy [PDF]

, 2013
Temperatures in the high pressure chamber of aircraft engines are continuously increasing to improve the engine efficiency. As a result, constitutive materials such as cobalt and nickel-base superalloys need to be thermally protected.

Comparison of oxidation behavior of YSZ and Gd 2 Zr 2 O 7 thermal barrier coatings (TBCs)

Surface and Coatings Technology, 2017
Abstract Yttria Stabilized Zirconia (YSZ) is widely used as a traditional ceramic top coat material in gas turbine engine components. Nowadays, rare earth zirconates, as alternative materials to YSZ, are enhanced for use as top coat layer of TBC owing to their better thermal isolation properties.
