摘要：

Yttrium aluminum garnet thermal barrier coatings (TBCs) deposited by the solution precursor plasma spray process (SPPS) have been shown to have a 200 degrees C temperature advantage compared to air plasma spray yttria-stabilized zirconia TBCs (Gell et al. in J Therm Spray Technol 27:1-13, 2018). These properties were generated on specimens and included phase stability to 1900 degrees C, improved sinter resistance, reduced thermal conductivity, and enhanced CMAS resistance. Part I of this paper describes the development of the SPPS processing parameters with different microstructures for three solar engine components (fuel nozzle injectors, annular combustor, and turbine ceramic outer air seals). This Part II paper describes the technology transfer to Solar Turbines Incorporated, coating of the three components and the successful rig and engine tests.
