Abstract

Thermal Barrier Coatings (TBCs) are crucial in high-temperature applications to improve the performance and durability of components. These coatings protect against heat transfer and damage due to high temperatures, but they can experience fatigue failure from cyclic thermal and mechanical loads. Therefore, testing TBCs for their fatigue life is critical to ensure their reliability and longevity. To test the fatigue life of TBCs, components are subjected to thermal cycling that simulates real-world conditions. The number of cycles required to cause failure is measured to determine the TBC's fatigue life. Fatigue testing results provide valuable information on TBC's durability, reliability and performance. It helps in identifying design and process parameters to enhance performance and reduce risk of failure. Thus, testing TBCs is an essential step to evaluate coatings for high-temperature applications, ensuring their reliability and durability and improving the longevity of protected components.

Introduction

A gas turbine's efficiency is dependent on the Temperature at the Entry to the Turbine (TET). The concept of TET motivates designers to find ways to increase this temperature (Sreenivas et al., 2015). The effects of the bond coat species on the
