Opis:: This study presents results of stress rupture test of MAR-M-509 cobalt alloy samples, as-cast and after surface refining with a concentrated stream of heat. Tests were conducted on samples of MAR-M-509 alloy castings, obtained using the lost-wax method. Casting structure refining was performed with the GTAW method in argon atmosphere, using the current I = 200 A and electrical arc scanning velocity vs = 100, 150, 200 and 250 mm/min. The effect of rapid resolidification of the MAR-M-509 alloy on the microstructure was examined and significant improvement in stress rupture test was observed.

Opis:: The paper summarises results of measurements of remelting area geometry, thermal efficiency and melting efficiency characterising the surface remelting process applied to castings of MAR-M-509 cobalt alloy. The remelting process was carried out with the use of GTAW (Gas Tungsten Arc Welding) method in protective atmosphere of helium, at the electric current intensity in the range from 100 A to 300 A, and the electric arc scanning velocity v_s in the range from 200 mm/min to 800 mm/min. The effect of current intensity and electric arc scanning velocity on geometrical parameters of remeltings, thermal efficiency, and melting efficiency characterising the remelting process has been determined.

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.

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.
