Abstract
A thermal spraying powder includes granulated and sintered particles of an yttrium-aluminum double oxide obtained by granulating and sintering a raw powder containing yttrium and aluminum. The total volume of fine pores having a diameter of 6 μm or less in one gram of the granulated and sintered particles is 0.06 to 0.25 cm. The thermal spraying powder reliably forms a thermal spray coating that is suitable for use where the thermal spray coating is subjected to a thermal shock in a corrosive atmosphere or an oxidative atmosphere and for use where the thermal spray coating is subjected to a thermal shock in a state where the thermal spray coating contacts a member that has reactivity to a base material.
