Investigation of hot corrosion behavior of thermal barrier coating (TBC) systems with rare earth contents

Arabian Journal of Geosciences, 2018
Thermal barrier coatings (TBCs) are extensively used to protect critical components such as aircraft turbines to provide thermal insulation at elevated temperatures. At high operating temperatures, damage mechanisms such as oxidation and hot corrosion result in spallation of TBC system.
