Rare Earth oxide coatings allow turbine engines to operate at record 3,300°F | The researchers created and tested new combinations of rare Earth elements, such as yttrium, erbium, and ytterbium.
The researchers have developed innovative rare Earth oxide coatings that enable turbine engines to operate at higher temperatures.
A University of Virginia-led research team has developed new protective coatings that allow turbine engines to run at higher temperatures before components begin to fail. “The potential benefits drive interest in coatings that act as a barrier against the reactive gases produced by combustion at these high temperatures that can damage turbine blades.” “By combining multiple rare earth oxides, tailoring properties to better protect the underlying substrate can be achieved with just a single layer,” said Kristyn Ardrey, a Ph.D. alumna of Opila’s lab and first author of the paper.
