Current research is consistent with Dr. Gell’s career professional interests of commercializing laboratory innovations. Ten years ago, the first ceramic coating was prepared by the new Solution Precursor Plasma Spray (SPPS) process. Considerable UConn research & development, with emphasis on the unique microstructural features generated by the SPPS process, has led to the development of a SPPS YSZ (yttria stabilized zirconia) thermal barrier coating (TBC) with half the thermal conductivity of the industry standard: air plasma spray YSZ TBC. In addition, the unique strain-tolerant microstructure of SPPS TBCs has led to the development of a new TBC, yttrium aluminum garnet (YAG), with more than a 200oC temperature advantage compared to TBCs now in use. We are working with engine manufacturers and coatings fabricators to commercialize these promising new TBCs.
