Abstract: A thermal spray powder is provided that contains, as constituent elements, a first element selected from W and Mo; a second element selected from Co, Ni, and Fe; a third element selected from C and B; and a fourth element selected from Al and Mg. The amount of the second element in the thermal spray powder is 20% by mole or greater. The mole ratio of the fourth element to the second element in the thermal spray powder is 0.05 or greater and 0.5 or less. The thermal spray powder has a crystal phase containing Co, Ni, or Fe; W; and C or a crystal phase containing Co, Ni, or Fe; W or Mo; and B. In an X-ray diffraction spectrum of the thermal spray powder, the peak intensity attributed to Co, Ni, or Fe is at most 0.1 times the largest peak intensity in the same X-ray diffraction spectrum.

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.
