Future improvements will occur as intermetallic compounds, ceramics, composite materials, and refractory metal alloys are eventually incorporated in advanced engines, although significant technical barriers must still be overcome before these new families of materials are incorporated in critical engine components. Because seemingly modest increases in upper temperature limits translate into huge benefits for engine performance, the large development costs associated with the introduction of new turbine blade alloys have historically been readily justified for even modest increases in temperature capability.)

. This latter benefit will allow TBCs to effectively fill the gap in materials capability for advanced engines between the current family of nickel-base superalloys (which are generally regarded as being at or close to their ultimate service temperature)
