Beschreibung
Zusammenfassung:	A method for applying a thermal barrier coating according to at least one embodiment of the present disclosure includes: a step of forming a top coat layer on a bond coat layer formed on a heat-resistant alloy base material of an object. The step of forming the top coat layer includes forming the top coat layer by thermal-spraying a suspension containing ceramic powder by high velocity flame spraying, while maintaining a temperature of the top coat layer at not lower than 300° C. and not higher than 450° C.
