AbstractABSTRACT: It is proposed to develop new thermal barrier coatings based on current MiTi Korolon coatings for the turbomachinery of the rocket engines. The proposed coating system will provide thermal and environmental protection and at the same time provides sufficient damping characteristics to prevent fatigue failure. Furthermore, when applied to the entire rotating group, including the shaft, the coating provides low friction and wear resistance to ensure reliable operation of the bearings. Korolon is a high temperature, scratch resistant flexible ceramic coating that has demonstrated excellent adhesion to nickel superalloys and thermal and environmental barrier characteristics that make it attractive to a wide array of applications to turbopump components. Collaborations will be established in Phase II with turbine engine OEMs to expand the application of the proposed coating system. BENEFIT: The coating technology developed in this program will have several civilian and military applications, aside from rocket engines. The proposed TBC can be used in UAVs, gas turbine engines, ramjet engines, cruise missiles, decoys, and small aircraft engines. The proposed technology also has a great potential for use in systems that require corrosion and wear resistant TBC coatings. Examples include: turbopumps, cryogenic liquid pumps/compressors, refrigerant compressors, and many others. The use of more efficient and durable TBC/EBC will lead to increased engine efficiency by maximizing turbine inlet temperature and/or reducing the amount of cooling air required for airfoils.
