US Patent 10240460 Insulating coating to permit higher operating temperatures

A gas turbine engine component includes an insulating coating that is adhered to a surface of the component that permits the component to operate at higher temperatures with reduced thermal stress. The coating can be selectively applied to one or more portions of a part feature where, in some embodiments, the part feature may include a portion that does not include the coating. The part feature can include recognized features of a component such as an interior surface of a hollow component, a back side of a blade track, a cooling hole passage, etc.
