Thermal barrier coating could boost efficiency of gas turbines

"A spin-out company from Imperial College London has developed a thermal barrier coating for gas turbine parts that can optically feed back its temperature and ageing status even while the engine is running at full speed.
The main application for the technology is in power-generating gas turbines, where the coating could help to achieve significant efficiency savings.
Ceramic thermal barrier coatings, including yttria-stabilised zirconia, are used for the so-called ‘hot section components’ of gas turbines, such as the blades." Thermal barrier coating could boost efficiency of gas turbines | News | The Engineer
