Abstract: PURPOSE: Provided is a thermal barrier coating material for a thermal barrier coating layer, which stabilizes the fine structure of the coating layer at high temperature and prevents the reduction of thermal barrier property, therefore, the lifetime of the coating layer is increased. CONSTITUTION: The thermal barrier coating material is produced by mixing zirconia(ZrO2)-based powder containing 5-15wt% of Y2O3 with 1-10wt% of Al2O3 powder uniformly and then molding the mixture powder and performing a cooling-hydrostatic pressure treatment. And the thermal barrier coating layer is formed by a process comprising the steps of: polishing and washing the surface of a ultra heat-resistant alloy; coating the surface of the alloy with a heat-resistant alloy comprising Ni, 22wt% of Cr, 10wt% of Al, 1wt% of Y by an electronic beam coating method; and coating the coating layer with the thermal barrier coating material by the electronic beam coating method.
