Title:
METHOD FOR CONSTRUCTING THERMAL BARRIER COATING, AND HEAT-RESISTANT MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/199725
Kind Code:
A1
Abstract:
This method for constructing a thermal barrier coating according to at least one embodiment of the present disclosure comprises a step for forming a topcoat layer on a bond coat layer formed on a heat-resistant alloy base material of a target object. In the step for forming a topcoat layer, a topcoat layer is formed by the thermal spraying, using a high-velocity flame thermal spray, of a suspension comprising a ceramic powder while holding the temperature of the topcoat layer at from 300-450°C, to form a topcoat layer in which, with reference to the area of the cross section of the topcoat layer, the percentage of the area of regions in which unmelted ceramic powder is agglomerated is not more than 0.15%.
