GAS TURBINE ENGINE PART COMPRISING A PROTECTIVE CERAMIC COATING, A METHOD OF MAKING AND USING SUCH PART Russian patent published in 2020 - IPC C23C24/08 C23C26/00 F01D5/28 

FIELD: protective coatings of parts operating in high-temperature media.

SUBSTANCE: invention is applicable in thermal barriers for protection of parts of aviation gas turbines made of superalloys. Detail of gas turbine engine with ceramic coating for protection from calcium and magnesium aluminosilicates, wherein the ceramic coating is formed on a substrate and contains Al₂O₃ in molar ratio of 33 to 49 %, Y₃Al₅O₁₂ with molar content of 21 to 53 % and yttrium-stabilized zirconium dioxide with molar content of 13 to 31 %. Method of making said part includes at least one step of forming said ceramic coating on substrate. Application of said part as part of gas turbine engine with ceramic coating, used at temperature over 1000 °C in oxidative medium and in presence of calcium and magnesium aluminosilicates.

EFFECT: coating is provided for protection of parts from aluminosilicates of calcium and magnesium, characterized by increased service life, in particular, in medium and operating conditions of aircraft gas turbine engine.
