摘要： A thermal spray powder of the present invention includes particles composed of molybdenum disulfide, and a coating layer provided on the surface of each of the particles. The coating layer is composed of a metal that is softened or melted at a temperature lower than the heat decomposition temperature of the molybdenum disulfide. The coating layer is preferably composed of copper. The thermal spray powder suppresses heat decomposition of the molybdenum disulfide contained in the thermal spray powder during thermal spraying.

摘要： 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.

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.
