Thermal barrier coating material with RF absorption capabilities at elevated temperatures

摘要

Embodiments disclosed herein include compositions that serve, among other things, the dual function of a thermal barrier and an RF absorber. The compositions can be applied as a single layer to an aircraft engine component, thus reducing the weight of the aircraft and eliminating an extra coating step in the manufacturing process. The coating materials are designed to protect the metal underneath from the high temperatures generated during engine operation, and also to absorb or scatter radiation which may incumbent on the metal during operation. In some implementations, the compositions comprise a two phase mixture of perovskite and magnetoplumbite.
