Materials Genome Enabled Development of 3100ºF-Capable Multilayer, Multicomponent Thermal and Environmental Barrier Coatings for CMCs

In this STTR program, QuesTek Innovations LLC, a leader in the field of computational materials design, will partner with the University of Minnesota to expand its computational Materials by Design® technology by developing a “design toolkit” that enables the subsequent design and development of novel, multilayer, multicomponent, high-performance T/EBC for CMC turbine components. In order to develop a T/EBC system capable of meeting all of the design requirements, this toolkit will then be applied to address critical technical challenges including developing a higher-temperature oxidation-resistant bondcoat while addressing thermo-chemical/mechanical compatibility between coating layers. QuesTek will lead the overall STTR program with the long-term objective to design and develop unique compositions to enable the application of T/EBCs for higher temperature gas turbines. Prof. David Poerschke from University of Minnesota (UMN) will be the university partner conducting experiments to support the design of high performance T/EBCs based on his expertise in the area of high-temperature oxidation and the environmental protection challenges involved in implementing SiC-CMC technology in gas turbine systems.
