Description

technical field

[0001] The invention relates to a device in the technical field of testing, in particular to a device for testing thermal shock resistance of a thermal barrier coating. Background technique

[0002] Thermal barrier coatings (TBCs) are generally coating systems consisting of a ceramic surface coating with low thermal conductivity and a metal intermediate bonding layer. Plasma spraying, electron beam physical vapor deposition and other technologies are used to prepare thermal barrier coatings on hot-end parts such as aero-engines to isolate heated parts from high-temperature gas, which can not only improve the engine's high-temperature corrosion resistance, but also further increase the working temperature. , and can reduce fuel consumption, reduce cooling gas, improve thermal efficiency, and prolong the service life of hot end components. Thermal barrier coating technology is widely used in aerospace, gas power generation, chemical industry, metallurgy, shipb...
