FIELD: machine building.
SUBSTANCE: method of the ceramic layer deposition, making a thermal barrier coating on the metal substrate (1), that contains the deposition of the said ceramic layer with a column structure. The said deposition is performed through a grid (10) perforated by holes (11) and located parallel to the surface of the substrate (1) such that to form at least two ceramic columns (5), separated from each other by a space (6). After the said operations the next stage of the deposition of the ceramic isotropic bed (7) is performed in each of the spaces (6). The said heat barrier coating is deposited on the turbine blade for the turbine machine.
EFFECT: thermal barrier having low thermal conductivity, well resistance to erosion and good adaptation for thermomechanical stresses.
