The manuscript presents a microstructure and mechanical properties of two layers of thermal barrier coating (TBC) deposited on a plate made of cobalt alloy MAR-M509. Based on measurements of microhardness made with Berkovitz’s indenter using Nano Scratch-Tester CSM Instruments, it was stated that elastic (Ee) to total energy (Ec) parameters (M_IT=Ee/Ec), γ phase, matrix of alloy MAR-M509 (M_ITγ), metallic interlayer (45%Ni – 22% Co – 17% Cr – 16% Al – 0,3% Y),(M_ITM) and ceramic layer (M_ITZrO2) there are proportion 0,29:0,22:0,50.
