Thermal barrier coating materials

PSZ is one of the most popular refractory materials and used as a thermal barrier coating material in combustion chamber and/or turbine vanes of jet engines. INIOO is also used widely as a material of turbine blades and vanes. For this reason, FGM of PSZ/INIOO was selected.

Second, in addition to the base material changes, many of today s combustors also have Thermal Barrier Coatings (TBCs), which have an insulation layer of the total thickness used is 0.015-0.025 inch (0.4-0.6 mm) and are based on Zr02-Y203 and can reduce metal temperatures by 90-270 °F (50-150 °C). 

Not mentioned in this review but certainly important to multiscale modeling related to solid mechanics are topics, such as self-assemblies, thin films, thermal barrier coatings, patterning, phase transformations, nanomaterials design, and semiconductors, all of which have an economic motivation for study. Studies related to these types of materials and structures require multiphysics formulations to understand the appropriate thermodynamics, kinetics, and kinematics. 

Understanding the behavior of the interfaces and bulk materials involved in thermal barrier coating failure due to the extreme environment created in aircraft engines is still in its infancy. This is primarily because the system involves complex interfacial chemistry and the materials issues span large length and time scales. In this review, we have focused on the atomic level characterization. Once that is specified, it will be imperative to draw links between the atomic and the microstructural scales in order to understand the materials failure mechanisms completely. 

Zirconia (Zr02) is an extremely versatile ceramic that has found use in oxygen pumps and sensors, fuel cells, thermal barrier coatings, and other high-temperature applications, all of which make use of the electrical, thermal, and mechanical properties of this material. Proof of the interest and usefulness of zirconia can be seen from the voluminous literature found on this material. This chapter is intended to provide a concise summary of the physical and chemical properties of all phases of zirconia that underlie the appropriate engineering applications.
