FIELD: electricity.
SUBSTANCE: substrate with a coating creating a thermal barrier comprises the specified substrate, the specified ceramic coating made of two ceramic layers, at the same time the specified coating has different thicknesses at different sections on the specified substrate. Between the internal ceramic layer and the external ceramic layer there is no metal layer. Besides, the specified coating on the specified substrate has the first area and the second area. The external layer is thicker, in particular, at least twice thicker, in the second area, compared to the ceramic layer on the first area in the specified substrate.
EFFECT: development of a thermal barrier with high resistance to heat and mechanical stresses.
