Opis:: 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.

Opis:: The manuscript presents microstructure, geometrical product specification and results of scratch tests performed on the interlayer of thermal barrier coating (TBC) with Rockwell’s intender. The TBC was provided by depositing two layers; metallic interlayer and external ceramic layer onto a plate coating made of cobalt alloy MAR-M509 in plasma spraying process. The surface of the casting was sandblasted with Al²O³ powder in an air stream before the TBC was introduced. Scratches were made along the cross-section from a mould material (MAR-M509) through metallic interlayer and external ceramic layer in the TBC. Friction force, friction factor and acoustic emission were recorded during the test. It has been proved that metallic interlayer in the TBC of ca. 200 μm thickness forms tough coating without pores with good cohesion values and very good adhesion values to the mould.

Opis:: In the paper, results of stress-rupture test applied to MAR-M-509 cobalt alloy specimens, in as-cast condition and with microstructure shaped under rapid solidification conditions are presented. The material for the study were castings of MAR-M509 alloy obtained by means of the investment casting method. The rapid solidification conditions were obtained by means of remelting process carried out with the use of GTAW method. The effect of rapid solidification following the remelting process is a refinement of microstructure in castings of MAR-M509 alloy and significant extension of the time to rupture in stress-rupture test.
