Results of investigations on obtaining the thermal barrier coatings (TBC) and their properties have been presented in the article. Coatings were formed by a thermal spraying method using a A3000 system controlled by computer and with a robot. For spraying the following materials: ZrO2xY2O3 and MeCrAlY as an interlayer were used. The coating structure examinations were made. Powder morphology was determined by the scanning microscope method. Tests by the thermal shock method were conducted in the air atmosphere by heating the specimens to 1200 degrees centigrade for 15 min. and cooling to 250 degrees centigrade for 5 min. Hot corrosion resistance tests were conducted at 900 degrees centigrade in the Na2SO4 medium. Tests showed low resistance of TBC coatings to that type of corrosion. The TBC coatings were formed on the combustion chamber elements.
