Abstract
This invention discloses new and improved multi-layer coatings for gas turbine engine parts that are exposed to elevated temperatures, such as blades and vanes in the high pressure compressor and turbine of multi-stage aircraft engines, by applying a diamond film over columnar thermal barrier coatings such as yttria-stabilized zirconia, improving the erosion resistance of the thermal barrier coating.
