Overview
Thermal-barrier coatings (TBCs) are refractory coatings which provide thermal insulation for turbine blades and vanes, as well as for combustion chamber liners in power generation, aviation gas turbines and rocket combustors. They allow operation at substantially higher surface temperatures than is possible with bare metal, and thus TBCs have been used to extend the life of components. These suffer from severe heat load cyclically during operation. This standard applies to the test method of cyclic heating to evaluate the thermal-barrier performance and cyclic heat resistance of the thermal-barrier coatings provided for high-temperature components, such as burners, rotor and stator blades etcetera, of power-generation gas turbines used in thermal power plants, aircraft engines and rocket engines. The responsible German standardization committee is DIN/DVS Joint Working Committee NA 092-00-14 AA "Thermisches Spritzen und thermisch gespritzte Schichten (DVS AG V 7)" ("Thermal spraying and thermal sprayed coatings (DVS AG V 7)") at NAS.
