Abstract
A method for applying a thermal barrier coating according to an embodiment, 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, which contains ceramic powder, with atmospheric pressure plasma spraying, while cooling a portion of a plasma flame by supplying water as a cooling fluid to a periphery of the plasma flame at a supply rate of not less than 25 ml/min and not greater than 100 ml/min.
