Background
Gas atomization powder production is a powder production process in which a rapidly moving fluid (atomizing medium) impacts or otherwise breaks up a metal or alloy liquid into fine droplets, which are subsequently condensed into a solid powder. Atomization is the best method for producing fully alloyed powders, the product of which is known as pre-alloyed powder. Each particle of this powder not only has exactly the same uniform chemical composition as a given molten alloy, but also refines the crystalline structure due to rapid solidification; eliminating macro-segregation of the second phase.
The atomization powder-making method is divided into two major categories, the "two-stream method" (crushing the alloy stream with an atomizing medium stream) and the "one-stream method" (crushing the alloy stream in other ways). 846 the former atomizing medium is divided into gas (helium, , nitrogen, air) and liquid (water, oil); the latter is e.g. centrifugal atomization and dissolved air vacuum atomization.
