Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; gas-turbine engines. ^ SUBSTANCE: proposed ceramic coating for working blades of turbines of gas-turbines consists of two or more layers separated by metal layers. Layers of materials connecting ceramic layers are chosen so that material with lower thermal expansion coefficient be arranged in zone of action of higher temperature, and material with higher thermal expansion coefficient be arranged in zone of action of lower temperatures. Height of ceramic fibers does not exceed twenty maximum cross dimensions. ^ EFFECT: increased durability of coating and its resistance to loads acting in direction square to axis of columnar fiber. ^ 2 dwg
