Abstract The mechanical properties, hardness H and modulus E, of thermal barrier coatings (TBCs) have been determined as a function of the thickness of bond coats (0.08, 0.14, and 0.28 mm) prepared using a high-velocity oxygen fuel (HVOF) thermal spray process. The top coatings were fabricated by an air plasma spray (APS) process. Behavior in a given

Microstructural effect on the radiative properties of YSZ thermal barrier coatings (TBCs)
International Journal of Heat and Mass Transfer, 2014Abstract Thermal barrier coatings (TBCs) are not the pure bulk materials, and they contain many different micro/nano structures caused by the plasma spraying process. The microstructures in the coatings play a very important role on mechanical and thermal properties, therefore, the coating properties differ hugely from those of the corresponding bulk

Composite ceramics thermal barrier coatings of yttria stabilized zirconia for aero-engines
Journal of Materials Science and Technology, 2019Composite ceramics thermal barrier coatings (TBCs) are widely used in the aero-engines field due to their excellent thermal insulation, which improves the service life and durability of the inherent hot components. The most typical, successful and widely

International Thermal Spray Conference, 2010 Abstract The very low pressure plasma Spray (VLPPS) process has been developed with the aim of depositing uniform and thin coatings with large area coverage by plasma spraying. At typical pressures of 100-200 Pa, the characteristics of the plasma jet change compared to conventional low pressure plasma spraying processes (LPPS) operating ...

Thermal barrier coatings (TBCs) commonly expose to oxidation, hot corrosion, and CaO-MgO-Al2O3-SiO2 (CMAS) attacks during the service condition. All of these attacks cause the spallation or delamination of TBCs from the bond coat.

Microwave Inspection of Thermal Barrier Coating (TBC) Systems
ASNT 30th Research Symposium Conference Proceedings, 2022Nondestructive testing (NDT) of thermal barrier coating (TBC) systems is a critical issue in their manufacturing environments. In particular, inspection techniques by which thickness of TBC topcoat can be accurately determined are currently being sought.

High Entropy Alloy (HEA) Bond Coats for Thermal Barrier Coatings (TBCs)—A Review
International Thermal Spray Conference, 2023Abstract Due to the aggressive operation conditions of turbine hot sections, protective coatings are required to provide oxidation and hot corrosion resistance for superalloy components. Thermal barrier coatings (TBCs) are comprised of a ceramic top coat and a metallic bond coat (BC) and are typically used as thermal protection systems ...
