FIELD: thermal engineering; designing coatings for holding molten material within gas-turbine engine enclosure. SUBSTANCE: method involves applying binder-containing coating material onto inner surface of external casing of compressor followed by plasma evaporation of heat-insulating ceramic coat overall. Mentioned device has substrate coated with binder-containing material and ceramic material overall, to hold combustion products of gas-turbine engine inside its enclosure. Optimal version has binder-containing coating made of Ni-Co-Cr-Al-Y alloy; overall coat may contain stabilized zirconium. EFFECT: improved quality of coating. 17 cl, 6 dwg
