In aircraft engines, various coatings are applied to relevant components to prevent deformations caused by factors such as high and low temperatures, wear, and oxidation-sulfidation. The role of coatings is critically important in aircraft engines with long life requirements; excessive stress-induced deformations not only reduce component performance but can also lead to serious engine damage.

Coating performance test systems are used to observe the performance of coated parts against sudden temperature rises and sudden temperature drops before their integration into the engine. In these test systems, precisely controlled thermal shocks are applied to coated surfaces to assess the parts’ resistance to thermal shock.

E2T provides turnkey coating performance test systems that simulate the real operating conditions of coated components in a laboratory environment. With the coating performance test systems developed by E2T, the thermal stresses that coated engine components will be exposed to are recreated in the laboratory so that development and verification processes can be carried out safely.
