Episode 48: Thermal Barrier Coatings

Did you know turbine blades operate in environments above their melting temperature? The secret is a barrier, no thicker than your fingernail, that insulates, protects, and prevents the nickel superalloy blade from melting. In this episode we discuss the materials science that makes low thermal conductivity, high compliance thermal barrier coatings possible. Towards the end we peer into what the future might hold as we push operating temperatures higher.
