Long lifespan thermal barrier coatings
Web16 de jun. de 2024 · Lifetime is a basic support for the thermal insulation function of thermal barrier coatings (TBCs). Therefore, extending the life span is essential to develop next-generation TBCs. For this objective, the columnar structure formed by vertical cracks appears to make sense. However, the underlying mechanism is still unclear. This work … WebThermal Barrier Coatings. The role of thermal barrier coatings (TBC) is, as their name suggests, to provide thermal insulation of the blade. A coating of about 1-200 μm can reduce the temperature by up to 200 C. A TBC can be used either: to reduce the need for blade cooling (by about 36%), while maintaining identical creep life of the substrate.
