Innovative materials design in thermal barrier coatings could boost energy efficiency

Researchers at the University of Virginia and Harvard University have made an exciting discovery in thermal barrier coatings (TBCs) that could significantly enhance the performance and efficiency of gas turbines, key components in power plants and jet engines.

Their study examines how substituting iron into yttria-stabilized zirconia (YSZ) impacts the material's ability to absorb radiative heat in the nearinfrared region of the electromagnetic spectrum, potentially leading to innovations that improve the efficiencies of energy systems we rely on every day, notes a press communique from the University of Virginia.

Gas turbines, which are essential for generating electricity and powering aircraft, operate under extreme temperatures. TBCS protect metal components from this heat, ensuring turbines can function safely and efficiently. Improving the efficiency of turbines is crucial because these systems consume vast amounts of fuel. Higher efficiency means burning less fuel to generate the same amount of energy, resulting in reduced costs for consumers and lower greenhouse gas emissions both of which are critical as the world transitions to more sustainable energy practices.
