[0002] Atomization powder preparation method is with the fluid (atomization medium) impact or with other ways to break metal or alloy liquid into small droplets, then condense into solid powder powder preparation method. Atomization method is the best method to produce completely alloyed powder, its product is called pre-alloyed powder, and each particle of this powder not only has the same uniform chemical composition as the given molten alloy, but also refines the crystalline structure due to rapid solidification; Eliminate the macrosegregation of second phase, the most widely used is gas atomization and water atomization method. When atomizing powder, first melt the metal raw material into alloy liquid (generally overheat 100~150°C) with electric furnace or induction furnace, then inject it into the tundish above the atomizing nozzle.
