PRODUCTION METHOD OF ATOMIZED POWDER FOR FLAME SPRAYING

摘要

PROBLEM TO BE SOLVED: To provide a production method of atomized powder for flame spraying where spray properties are excellent and the properties of obtained spray deposit are excellent. SOLUTION: Powder produced by an atomization method is accumulated to a prescribed thickness, and vibration is applied to the accumulated powder to remove deformed particles and hollow particles coming to the surface layer part of a layer comprising the accumulated powder. It is preferable that the vibration applied to the powder is horizontal rotating vibration, and the revolution number per min is 20-50 rpm and the rotating radius is 5-100 mm. The horizontal rotating vibration can be carried out by a circular vibrator. A container 3 is put in the circular vibrator, and it is preferable that the powder to which the vibration is applied is fed into the container so that the depth of the powder is≥1 cm and≤5 cm.
