MATERIAL OF CERAMIC LAYER OF HEAT PROTECTING COATING Russian patent published in 2015 - IPC C23C14/08 C23C30/00

Abstract RU 2556248 C1

FIELD: machine building.

SUBSTANCE: invention relates to machine building, and can be used in aviation and power turbine engineering to apply the heat protecting coating on the tract surface of work and nozzle blades of the turbine of the gas-turbine engine. The ceramic heat protecting coating for the products out of heat-resistant cast nickel alloys contains in wt %: Gd₂O₃ - 2-9; Y₂O₃ - 7-9, and ZrO₂ - rest.

EFFECT: increased in range of work temperatures 1100-1150°C of heat resistance and coefficient of thermal conductivity of coating to 1 W/m·K.
