If you've flown in a turbine-powered aircraft recently, you almost certainly flew in a plane that used thermal barrier coatings (TBCs) in the engines. What's more, if the plane you rode in used current generation turbine engines, the TBCs were included as a part of the initial engine design. This represents a significant change from relatively recent thinking, when TBCs were considered a "Band-Aid" solution to thermal management problems in turbines. The vast change in attitude is the result of one overriding factor: TBCs work.
