Thermal Barrier Coatings for Gas-Turbine Engine Applications-A Review

Abstract

Thousands of possible types of coatings have been used in the protection and lubrication and thermal insulation of various structural engineering components from corrosion, wear and erosion. Thermal barrier coatings (TBCs) are one of the most difficult structures and must work in the most challenging aircraft and industrial gas turbine motors high-temperature environments. TBCs, which consist of multidimensional metal and ceramics, isolated turbine and hot gas stream turbine engine parts and enhance the sustainability and energy efficiency of these engines. Enhancing TBCs would require better understanding of the dynamic structural changes and the features that emerge under operating conditions resulting in their failure. In this article, the different thermal barrier coatings on  blades increase the life of the engine components.
