This technology is a multilayer thermal barrier coating that can decrease the radiative load on underlying metal substrates by almost two orders of magnitude, reducing cooling and increasing efficiency of coated gas turbines.
Current state-of-the-art thermal barrier coatings that provide thermal resistance and enhance the durability of metal parts in gas turbines do not effectively shield from the thermal radiation emitted by combustion gases. This limits the maximum turbine inlet temperature and, thus, the efficiency of gas turbines.
This technology is a multilayer thermal barrier coating that can enhance the efficiency of gas turbines by shielding thermal radiation emitted by the combustion gases within. The coating is comprised of multiple layers of thin films that shield the metal them from both visible and infrared thermal radiation wavelengths. The coating reflects most of the thermal radiation from combustion gases at temperatures around 2000 K to decrease the radiative load on underlying metal substrates by almost two orders of magnitude. This leads to reduced cooling and greater efficiency of coated gas turbines.
