PROCEDURE FOR COATING WITH CERAMIC MATERIAL OF TUNGSTEN BRONZE STRUCTURE AND PART OF TURBINE WITH HEAT-RESISTANT COATING Russian patent published in 2011 - IPC C23C14/08 

FIELD: metallurgy.

SUBSTANCE: part of turbine has substrate with corresponding oxidation resistant metal layer as binding and coating resistant to heat. Heat resistant coating consists of ceramic cover material of tungsten bronze structure. The metal layer resistant to oxidation is under said ceramic cover material. Ceramic cover material of tungsten bronze has formula BaO-RE₂O₃-xTiO₂, where RE is rare earth lanthanide, while x is within the range from 2 to 5. Resistant to oxidation metal layer corresponds to MCrAlX-layer, where M is chosen from elements of the group consisting of Fe, Co, Ni or their mixtures, while X is element chosen from elements of the group consisting of Y, Si, Hf and rare earth elements or their mixtures.

EFFECT: fabrication of turbine part operating at higher working temperatures due to improved thermal isolation of heat resistant coating applied on this part.
