INVENTOR • Otto Gregory, Markus Downey
A superalloy article of a substrate, bond coat (cobalt, nickel or mixtures thereof) applied onto the substrate, and a ceramic top coat applied over the bond coat. The bond coat is exposed to a 1600-1800 degrees F after its application onto the substrate.
The composites can be used for thermal sprayed instrumentation or as thermal barrier coatings for engine parts of automobile engines, gas turbine engines and turbines for power generation.
FEATURES & BENEFITS
Addresses challenges associated with monitoring the temperature and strain of the various engine components operating at temperatures > 2200 degrees F. Improves fatigue life of the sprayed coatings used to embed strain gages and thermocouples. Reduces any internal oxidation in the bond coat.
