摘要： 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 cm3. 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.

摘要： A thermal spraying method and thermal spraying system of the present invention jets thermal spraying powder supplied from a feeder through a connecting conduit by softening or melting the thermal spraying powder using a thermal spraying machine. By setting the internal atmosphere in the connecting conduit to a negative pressure relative to the atmosphere near the intake end of the connecting conduit, the thermal spraying powder stored in the feeder is suctioned into the intake end of the connecting conduit. The thermal spraying powder suctioned into the intake end of the connecting conduit is carried to the discharge end of the connecting conduit, introduced inside a cylindrical air flow jetted from the nozzle provided in the thermal spraying machine or introduced into a combustion chamber provided in the thermal spraying machine or into the jet nozzle, softened or melted and jetted out.
