Abstract (en)

A thermal spraying powder is characterized in that 90% particle size D90 of the thermal spraying powder is 15 µm or less. The thermal spraying powder is also characterized in that the ratio of the total volume of particles having a particle size of 1 µm or less to the total volume of all particles in the thermal spraying powder is 2% or less. A value obtained by dividing the bulk density of the thermal spraying powder by the theoretical density of material forming the thermal spraying powder is preferably 0.15 or more. The particle size dispersion index of the thermal spraying powder is preferably 0.7 or less. A thermal spray coating that is dense and has a small surface roughness is reliably formed using the thermal spraying powder.
