Parametric Studies Of Failure Mechanisms In Thermal Barrier Coatings During Thermal Cycling Using FEM

International Journal of Applied Mechanics and Engineering, 2015
Thermal barrier coatings (TBCs) are widely used on different hot components of gas turbine engines such as blades and vanes. Although, several mechanisms for the failure of the TBCs have been suggested, it is largely accepted that the durability of these

Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials

Advanced Optical Materials, Volume 14, Issue 2, 14 January 2026.
Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).
