Abstract:

Complex diffusion-condensation protective coatings characterized by gradient distribution of alloying elements over the thickness due to formation of a diffusion barrier layer on the surface of blades followed by deposition of condensation alloyed layers based on the Ni-Co-Cr-Al-Y system and an external layer based on a NiAl alloyed beta-phase and a ZrO2: Y2O3 ceramics are presented. A complex gradient coating possessing unique protective properties at t = 1100-1200 degrees C for single-crystal blades from alloy ZhS36VI for advanced gas turbine engines with gas temperature of 1550 degrees C at the inlet to the turbine is described.
